A Jacketed glass reactor used in the chemical & pharmaceutical industries is an equipment designed to regulate the temperature of its content by using a “jacket” either for cooling or heating around the vessel in which a heating or cooling fluid circulates. Agitation can also be used to increase the homogeneity of the fluid properties such as concentration or temperature in jacketed glass vessels.   How does it work? Via a double lined glass reactor interlayer, material or liquid is injected into glass reaction vessels with thermally dissolved or cooling process. Link the external Cooling or Heating equipment with the Double Lined glass reactor. Make sure to stir the material or liquid that is heated by an Agitator at constant level. It can churn and react in the sealed reactor, under the natural or negative pressure. After reaction, the material can be drained from the outlet valve given at the bottom of the reactor, the operation of which is very simple. The reactor is the perfect tool to conduct experiments for biochemical, modern chemistry, advanced synthetics studies, and pharmacy.   Pertinent Features It is built with Borosilicate glass 3.3 and has excellent physical as well as chemical properties.

The jacket is capable of enabling the uniform heat exchange between the fluid that circulates in it and the vessel’s walls. http://www.ablazeexport.in/blog/gas-absorber-systems-operation-and-application_9215.htm Mon, 31 Aug 2020 10:38:13 +0530 What is a Gas Absorber? Gas absorbers are used to eliminate pollutants from gas flows, such as methane from an exhaust discharge. A Gas absorption unit uses a column which often contains material for random or organized packing. Packed bed absorbers use fluxes of gas and liquid that flow counter current one to another. The contaminant gas is absorbed into the fluid stream, resulting in the exit gas being reduced as contaminant. The process of absorption is heavily dependent on the operating parameters which have to be studied to optimize the process. Let’s take an example of investigating the carbon dioxide absorption into water, and examine how the operating parameters affect system separation and efficiency.   Operation / Working A Gas absorption unit uses a liquid solvent touch to absorb the material from a gas mixture. Energy is moved from the gas mixture to the solution, with equilibrium of the two phases. Instead, there is the isolation of the liquid gas phase. The overall material balance for the absorber is where the vapor and liquid flow rates respectively, thereby integrating the mole fraction in the vapor and liquid phase into the component material balance for the absorbed component.   The average coefficient of mass transfer is the rate at which the concentration of one material transfers from one substance to another. Here in this example, let’s consider KG as the total mass transfer coefficient, and PAG is the partial gas pressure that needs to be absorbed.   Mass transfer depends on the coefficients of mass transfer at each step, and the amount of interphase area available in the absorber. Henry's Law and Raoult's Law are applied to determine the concentration of the liquid phase partial pressures in equilibrium.    A packed column Gas absorber will be used in the following experiment to absorb carbon dioxide from a flux of gas into water. From the bottom and top respectively the gas and water streams enter the column allowing counter flow. The composition of carbon dioxide at the inlet is controlled using the carbon dioxide and air valves. Then, the carbon dioxide concentration in the outlet is measured.   The device used in the above example is a column for the absorption of packed counterflow air. At a bed depth of 34 centimetres, the column is filled with 13 milliliter berl saddles. The valves at the column's entrance and exit allow gas to escape, while an infrared spectrometer is used to measure partial CO2 pressures during the gas process.    Turn on the master switch to start the experiment then close the valve used to regulate the amount of water in the tank. Open the airflow valve full, and open the column pressure control valve. Set the airflow rate considering your desired level. Use at least 30 liters per minute, then raise the level as desired. Set column pressure to approximately 0.5 bar using a pressure control valve. Set the carbon dioxide flow rate to about 4 liters per minute, then set the water flow rate to about 4 liters per minute, too. Throughout the experiment change the water flow to maintain a steady water level within the tank using the in-line pressure gauges to sample and measure the carbon dioxide concentration at the base, middle and head of the column as needed.   Repeat the experiment by performing eight runs. Use two different gas flow rates, liquid flow rates, and carbon dioxide concentrations, thereby enabling the determination of the most important variables in the system. You must make sure that system is allowed to achieve its steady state whenever a flow rate is changed.   Repeat the experiment 8 times, using two distinct gas flow levels, carbon dioxide concentrations, and liquid flow rates to assess the system's most critical variables. Make sure that the system maintains a steady state if a flow rate is modified.   Let's have a look at the results of the experiment conducted. First, measure partial pressures and partial pressure balance for each phase, then use the partial pressures to determine the coefficients of mass transfer. The estimated values are represented here as triangles, while the expected values, shown as the solid line, derive from the operating and equilibrium lines measured. Confidence intervals were plotted with dotted lines for the model values and the mean coefficient of mass transfer.   There was no difference between the expected and actual values, suggesting that at the interface between the liquid and gas phases, the column is at a steady state of equilibrium. Now let's see what happens, when we compare the coefficients of the mass transfer under the same operating conditions. If the rate of gas was high or small, the model and experiment act the same, demonstrating that the rate of gas flow had little to no effect on the coefficient of mass transfer in the ranges tested.   Applications Then, let's take a look at some industrial applications where the Gas absorber is used. Packaged bed absorbers are the most common piece of equipment used for controlling air pollution. Gas absorbers are also called scrubbers in such situations. Scrubbers are used to extract corrosive gases from toxic gasses and vents from oil refineries, chemical plants, and paper and pulp factories, such as nitric acid, sulfuric acid, and hydrochloric acid. The discharge process of the dissolved gas from the solvent is called stripping. Strippers are also used along with absorbers to extract the dissolved gas and recycle the liquid solvent. This is especially relevant when components of nitrogen and phosphorus are in the wastewater. This waste water used to be drained directly into oceans, but this resulted in excessive algae production, called eutrophication, which in turn was affecting the natural habitats severely.   Final thoughts Ablaze Export Pvt. Ltd. focuses on the Gas absorption Unit analysis, in a simple way where only a single element in the gas solution is absorbed. All the other elements of the gas are considered as non-soluble in the liquid, and there isn’t any transfer of elements from the liquid phase to the gas phase as the liquid present inside becomes non-volatile. We design Gas absorbers that can be used for plenty of industrial purposes such as to extract corrosive gases from the toxic gases as well as vents from the oil refineries, and chemical plants. It is also used in the pulp & paper factories, to remove toxic gases such as hydrochloric acid, nitric acid, and sulfuric acid. http://www.ablazeexport.in/blog/everything-you-need-to-know-about-shell-and-tube-heat-exchanger_9216.htm Mon, 31 Aug 2020 10:40:35 +0530 Heat exchangers are machines that transfer energy from one working fluid to the next in the form of heat, whether it is solids, or liquids, or gases. Such devices are important for cooling, power generation, HVAC, and much more, and come in several shapes and sizes that can either insert or remove heat. It is often difficult to understand what makes one heat exchanger special from another, so this article will help readers gain introductory information on one of the most common heat exchangers, widely accepted as the shell and tube heat exchanger.   What is Shell & Tube Heat Exchanger All heat exchangers are based on the same concept, namely that a hot fluid flowing over or around a colder fluid must transfer its heat (and thus its energy) in the direction of cold flow. Think of when you first grabbed your steering wheel on a cold day: the temperature difference between your hand and the wheel is big at first, and you can feel how cold it is; but, if you keep grabbing the wheel, the cold wheel can absorb some of the heat in your palm, and the wheel can "warm up."   In a simple way, the Shell and tube type heat exchangers are a system that places two working fluids in thermal contact using tubes housed within the outer cylindrical shell. Typically these two integral pathways are made of thermally conductive metals such as aluminum alloys, steel, etc which allow the easy heat transfer. The tubes hold a fluid from their inlet to their outlet (the "tube-side" flow), while the shell flows a different fluid (the "shell-side" flow) through these tubes. The number of tubes, known as the tube bundle, will determine how much surface area is exposed to the shell-side flow, and therefore how much heat is transferred.   These devices are categorized among the devices giving the most effective means of heat exchange, as they are simple to create, maintain, are compact and provide excellent heat transfer. These are commonly used in industry, and are useful for a variety of purposes such as turbine coolers, condensers, preheating feed water, evaporators, and more.   How does it work? Figure 1 above, demonstrates the standard shell and tube type heat exchanger setup, with easily readable labels. As explained previously, the fundamental purpose of heat exchangers for shells and tubes is to move a hot fluid through a cold fluid without mixing it, so that only their heat is transferred. The diagram above shows two inlets and two outlets, where each fluid begins at its respective inlet and exits the device at its outlets.   The movement of the tube-side passes through the bundle of the tube (secured by metal plates known as tubesheets or tubeplates) and exits the outlet. Likewise the shell-side flow begins at the inlet of the shell, flows through the tubes and exits at the outlet of the shell. The headers on either side of the tube bundle create tube-side flow reservoirs and may be divided into sections according to specific types of heat exchangers.   Each tube contains an insert known as a turbulator that induces turbulent flow through the tubes and prevents deposition of the sediment, or "fouling," as well as raising the heat transfer ability of the exchanger. Designers also cause shell turbulence with barriers known as baffles, maximizing the amount of thermal mixing that occurs between the fluid on the shell side and the coolant pipes. The shell-side fluid must work its way through these baffles, allowing the liquid to travel through the tube bundle repeatedly, thus transferring energy and leaving the heat exchanger at lower temperature. Some shell and tube exchangers use different heat transfer types, and others use nothing at all.   The heat exchangers for shell and tube may be single-phase, or two-phase. A single-phase exchanger keeps the phase of the fluid constant throughout the process ( e.g. entering liquid water, leaving liquid water) while a two-phase exchanger causes a change of phase during the heat transfer process (e.g. entering steam and leaving liquid water). They may also be single pass or multi pass, which simply defines how many times the flows on the side of the tube-side or shell-side pass through the system.   Pertinent Features They have colossal Heat Transfer Surfaces. They have high Heat Transfer Coefficients. The sides of Shell, as well as Tubes, can be made diffusion and corrosion-resistant.

They 're found in nearly every organic lab. By heating, the rotating flask rotates and forms a thin film under negative pressure; it evaporates, and then the vapor is concentrated, liquefied, and removed for recall.   A typical thin-film evaporator is fitted with a water bath that can be heated in either a metal tub or a crystallizer. That holds the solvent freezing during the process of evaporation. In a vacuum, the solvent is removed, trapped by a condenser, and stored for quick reuse or disposal.   For a rotary evaporator, we will include the whole solution along with the rotating chiller and vacuum pump.   The Process of Rotary Film Evaporator The rotating flask constantly covers a wide area of the surface with a thin film that is perfect for fast heat transfer. Luckily, the thin film often allows an even distribution of heat without local heating. Therefore the facility to operate the device under full vacuum enables evaporation at the lowest possible temperature. That is, both the boiling point and the time spent in the house are substantially reduced. These features combined, make rotary film evaporator ideally suited for heat-sensitive material evaporation. It is equally effective in crystallization processes for the evaporation of suspension, drying of powder/granules, etc.   Rotary evaporator/vacuum evaporator sees wide use of industrial activity from small-scale laboratory set-ups. Ablaze Rotary Film Evaporator is favoured by research as well as production facilities and is used by the laboratory & chemical, biotechnology as well as the pharmaceutical industries.   Construction of Rotary Film Evaporators Ablaze Rotary Film Evaporators are fully self-contained units that consist mainly of the following:   An electrically heated SS heating bath with height-raising and height lowering equipment. Rotating flask of borosilicate glass resistant to corrosion which is linked by coupling to move. The drive is a hollow glass shaft that also serves as an off-take conduit for vapour. The driveshaft is sealed into a Teflon coated condenser/receiver. Power is transmitted to the shaft by an engine-driven gear with varying speeds given.   Pertinent Features It has a universal heating bath capacity up to 200°c.

It can be used in reflux process reactions. It can be used in component drying. It can be used in fine chemical synthesis. It can be used in crystallization. Rotary Film Evaporators are used in the Scientific Research, Medical Industry, and Chemical & Biological Product Processing industry as a part of the industrial applications.    Laboratories require a rotary evaporator to teach experiment processes in colleges and universities. It is an effective distillation unit for various laboratory experimental applications such as extract separation of solvents, reaction mass or solution concentration, regular solvent distillation, crystallization, etc.   Often seen in the Cooking Industry for Molecular Cooking is the new use of Rotary Evaporator, using the concept of molecular gastronomy to apply physical and chemical concepts in cooking. Rotary Evaporator is also used for a non-heating process to evaporate the air. It retains a sticky aromatic odor that can be quickly lost by heating.   Advantages of Rotary Film Evaporators The rotary evaporator has a lifting and dropping engine built-in. If there is a power loss or control loss, this system will automatically lift the rotary bottle to a certain position above the water bath. The liquid sample forms a liquid film on the inner surface of the evaporation container, which has a large heating field, due to the centripetal force and friction between the liquid sample and the evaporating tube. The speed of evaporation can get bigger in this way. During rotation, the sample's effect effectively suppresses the sample boiling.   Final Thoughts Ablaze Export Pvt.

A process used to purify solvents, additives, natural ingredients, gasoline, biodiesel, crude oil and other materials is Fractional Distillation. The fractional distillation unit separates different components by their boiling points. The more efficient the column is for distillation, the better the separation. Fractionation may be performed either in a conventional column for packed distillation or in a column for rotating band distillation. Heating bath heat and vaporizing the vessel content. Vapors join the column packed and are fractionated. Low boiling liquid vapors join the condenser, are concentrated and deposited into the twin receivers. By breaching the vacuum, the distillate from the final receiver may be extracted. The package is complete with a spherical reservoir, drain valve, a pocket thermometer, a heating pad, a product cooler, packing column, liquid inlet, coil condenser, and the twin receivers.   The Fractional Distillation Process The basic steps to the Fractional Distillation Process are as follows:   Connect heat to a liquid mixture of two or more principal ingredients, such as a mixture of water and ethanol.  Components with the lower boiling points will begin to vaporize and rise through the column as the liquid heats. Ethanol would first boil off in the water / ethanol example (BP 78 ° C, compared to water (BP 100 ° C). The growing vapor will therefore also contain some of the other substances' molecules. The higher it grows in the tube, the purer the vapor becomes, as heavier molecules condense and becomes liquid again. When vapor rises in the column of distillation, heavier molecules condense back into liquid and "pour" back downwards. Vapor will rise at any given point in a fractionating column, liquid will fall, and molecules will mix. Naturally, columns have such "stages;" a stage is a column region with a certain amount of molecules of each form of material ( i.e., a general percentage of water and ethanol). Columns are constructed by determining the minimum number of necessary stages to be tall enough to achieve a certain percentage separation. Vapor reaching the top of the column (distillate) is gathered through an industrial condenser (a large chiller), which refrigerates the vapor back into a liquid and pipes it into the tank or storage.  The remaining substances in the column continue the distillation cycle, until the desired purity is reached. Some columns are a (most common) continuous cycle, where new base solutions are continuously added. Others are batch systems, where when a desired separation is reached the base is removed. For certain processes the solution is recirculated many times to ensure proper separation of substances. The basic process of distillation is what's mentioned above. Sometimes in industry a distillation column is called a fractional distillation column. Columns which separate only two substances can be called columns which fractionate. Typically a fractional distillation unit at several points inside the column produces many different products. Mixtures may be pulled at various stages as liquids grow, and get condensed.   An easy example to think about is crude oil distillation, as the How Stuff Works explains. When the crude oil rises in a column, the column pushes out heavy oils lower. Diesel and gasoline climb higher, and are further pushed up the pole. Each of these substances originates from the same "source solution" but includes different percentages of the components contained in the material.   Pertinent Features The reactor is available up to 500-liter capacity.

All the wetted parts are built from the Borosilicate Glass, and PTFE which are considered as universal corrosion resistant materials. It has low CAPEX, and is easy to maintain. It has a Zero Hold-up in reflux divider.   Advantages of Fractional Distillation Easy implementation: One of the greatest advantages of fractional distillation is its easy to use. So long as you are setting up a fully functioning and well-designed program, you should leave it to do the job as it is. You just need to periodically test the device to ensure it works correctly, figure out if it needs upgrades, and fix whatever needs to be fixed. Using microprocessors, modern fractional distillation setups are automated which make the process even easier.   High efficiency: Innumerable experiments and actual processes have proven to be effective in fractional distillation. In reality, it's commonly used to produce the goods that modern society needs in many industrial settings. Fractional distillation being highly efficient, particularly for systems using stacked distillation columns which is known to produce more output at lower cost.   Production of Fuel: Fractional distillation unit is used to refine crude oil and manufacture diesel, kerosene, gasoline, naphtha and bitumen (used for roofs and roads). Keeping this in mind, it is convenient to infer that fractional distillation has done plenty to advance and modernize human life.   Ability of handling any waste streams: Since Fractional Distillation Equipment are customized to the customer's specific specifications, the precise ratios, compounds and concentrations are taken into account to ensure the best possible quality of the finished product. This is capable of recycling the alcohols, solvents, oil & gas, as well as other chemicals and compound combinations.   Flexibility and Compatibility of working with any industry size: It is important to know how much waste you generate which would entail recycling while considering a custom-made piece of equipment. Many Fractional Distillation units can work either in a batch (waste is added as produced) or via a continuous (automated) feed method. These can also be built to handle the feed sizes from as low as 1 gallon per hour to as huge as 500 gallons per hour.   Final thoughts We are Ablaze Export Pvt.
