Thus this absorption is a pollution abatement as well as a recovery process. The absorption can be done by two different methods : 1) Adiabatic Absorption :  This method is suitable when inerts like air, Cl2, phenolic compounds etc are substantial.  2) Isothermal Absorption  :  This method is suitable when inerts like air, Cl2, phenolic compounds, etc are negligible. Nitric Acid Plant http://www.bvres.com/nitric-acid-plant.htm http://www.bvres.com/nitric-acid-plant.htm Thu, 28 Jul 2022 00:00:00 +0530 Concentrated Nitric Acid CNA Plant http://www.bvres.com/concentrated-nitric-acid-cna-plant.htm http://www.bvres.com/concentrated-nitric-acid-cna-plant.htm Nitric Acid Plant Fri, 05 Aug 2022 00:00:00 +0530 Nitric Acid Concentration Concentrated Nitric Acid CNA ( i.e. high-strength nitric acid at 98 -99% w/w.) is an important chemical for Chemical & Pharmaceutical industries in general (like polymers & plastics, dyestuff, bulk drugs, explosives, Fertilizers and other important organic nitro-compounds). This acid is frequently used as "nitrating acid". Industrially manufactured Nitric acid is obtained as a weak acid solution, at a concentration of about 65% -67% w/w (max.), which is of no use whatsoever for the various processes stated above, Owing to the physical behaviour of the nrtric acid / water system, it is not possible to remove excess water from this weak acid by a fractional distillation process because this solution forms an azeotrope, a constant acid / water boiling composition at about 68% w/w. acid. To concentrate this acid further an extractive distillation process by adding concentrated sulphuric acid needs to be employed. While the water goes this sulphuric acid gets diluted, which can be again re-concentrated and reused for the concentration of dilute nitric acid again. Reconcentration of weak Sulphuric Acid The dilute sulphuric acid stream coming off the bottom of the Extractive Distillation Column is reconcentrated back to the same service by using BVR's sulphuric acid re-concentration plant, which can be coupled directly with the nitric acid concentration system so that no cooling of the weak sulphuric acid is necessary, thus saving a large amount of heating energy for the economical benefit of the user. NOx Absorption The NOx gases escaping from the Nitric acid Concentration System, along with bleaching air, are absored in BVR's special NOx absorption plant and is recycled back into the main system as an aqueous solution of nitric acid, at concentration comparable to those of the nrtric acid feed to the same System : the residual gases vented to the atmosphere have NOx. content below the acceptable values as per environmental norms. Pre-concentration of weak Nitric Acid solution Whenever a solution of Nitric Acid is too weak for direct Extractive Distillation (typically below 45% -50% w/w.), it can be pre-concentrated to its azeotropic grade by our vacuum Fractional Distillation plant. NOx Absorption Plant http://www.bvres.com/nox-absorption-plant.htm http://www.bvres.com/nox-absorption-plant.htm Nitric Acid Plant Fri, 05 Aug 2022 00:00:00 +0530 NOx is the generic name given to Nitrogen Oxides. NOx is generated from many processes including nitration process, for both organic and several inorganic compounds (including a few important metals). This is generated due to the partial degradation of Nitric Acid used in the nitration process, as well as to the final treatment of the "spent" acid. These gases are also formed in the nitration of aromatic compounds (toluene, naphtalenes and many of their derivatives), including the production of practically all types of explosives, in the attack of some relevant metals (like copper, bismuth, etc.), in gold & silver refineries and also in the "Nitric Acid Concentration (NAC)" Plants. BVRs NOx Absorption Plants, uses water or caustic solution as per the need. Proper oxidation of NO is completed for the optimum absorption efficiency with minimal energy consumption. When absorbed with water Nitric acid produced can be re-used for re-use in the main process. Both absorption under atmospheric pressure and higher pressures are possible. At lower pressures the acid concentration is low and so is the absorption efficiency with a higher level of emissions. With Pressurised absorption the acid concentration could reach upto 50%w/w and the emission would be considerable lower too.

We have carved a niche as one of the overruling Rotary Evaporator Manufacturers based in India. In addition to this, we are also counted among the major Rotary Vaccum Film Evaporators Suppliers. The Rotary Film Evaporator is essentially a Thin Film Evaporator incorporating a rotating evaporation flask. The rotary evaporator will evaporate solvent at a much faster rate than systems using stationary evaporation flasks, due to higher convectional heat transfer coefficient. The rotation transfers a thin film of the liquid to the whole of the inner surface of the flask, markedly increasing evaporation rate due to higher heat transfer between the flask, bath and the thin film. The rotating flask and vapour duct have a sealing system, which allows operation under vacuum, further accelerating the evaporation process because of the reduction in boiling point of the solvent and efficient removal of the vapour. Besides the reduction in boiling point, there is a considerable decrease in the residence time of the fluid, which also permits heat sensitive materials to be successfully concentrated without degradation. The evaporators can be evacuated down to less than 1 mbar if the vacuum seals are maintained in good condition. A continuous feed facility considerably increases the capacity of the units and distillate withdrawal facilities on some units allow uninterrupted operation. Features Digital display & auto control of rotation speed, vapor temperature and bath temperature.   Miniature circuit breaker and separate power switches for control panel and heating bath offers safety.   Vacuum Controller (Optional) RS-232 / 485 interface (Optional) The units can be offered with full automation incorporating a PLC based system or even SCADA for real time data acquisition and control. There is a range of models covering an evaporation flask capacity from 1 litre 5 litres. The majority of these models may be used on the laboratory bench; the larger models (10, 20, 50, 100 litres and above) are designed for use in pilot plants and production facilities.   Heat Exchanger http://www.bvres.com/heat-exchanger.htm http://www.bvres.com/heat-exchanger.htm Fri, 05 Aug 2022 00:00:00 +0530 We have firmly positioned ourselves as one of the leading Tube Heat Exchanger manufacturers and Exporters based in India. Our Industrial Heat Exchangers are manufactured from glass, SS or exotic metals, SiC (Silicon Carbide), other internals could be of PTFE or other Fluoropolymers.

SiC heat exchangers are suitable for long-term operation as condensers, evaporators or coolers for highly corrosive media and can be used in multi purpose plants or for stand alone applications too. Solvent Extraction Plant http://www.bvres.com/solvent-extraction-plant.htm http://www.bvres.com/solvent-extraction-plant.htm Fri, 05 Aug 2022 00:00:00 +0530 Liquid extraction, sometimes called solvent extraction, it the separation of a liquid of a liquid solution by contact with another insoluble liquid. The Fully Automatic Solvent Extraction Plant described is for semi-batch operation. The liquid to be extracted is poured into extraction vessel. Solvent is boiled in a reboiler vessel and condensed in an overhead condensed, the condensed liquid in a reflux divider and passing through pipe work to the extraction vessel. The pipe work incorporates valve in order that the solvent can enter the extraction vessel at either the base of the top, depending on the relative density of the solvent and liquid to be extracted. The solvent and the extracted liquid pass back to the reboiler and the process is reputed until the extraction is complete. The extraction vessel is than drained and the solvent evaporated from the reboiler vessel and collected in the extraction vessel enabling the two liquids to be drained from their respective vessel. The Solvent Extraction Plant is available in vessel size upto 500 Ltr. and is suitable for operation under atmosphere pressure and vacuume. Today, we have carved a niche as one of the prime Modular Solvent Extraction Plant Exporters based in India. Wiped Film Evaporators http://www.bvres.com/wiped-film-evaporators.htm http://www.bvres.com/wiped-film-evaporators.htm Fri, 05 Aug 2022 00:00:00 +0530 We are one of the corrosion resistant Wiped Film Evaporators Manufacturers based in India. Wiped Film Evaporator is a Thin Film Evaporator and consists of a jacketed glass / SS / other corrosion resistant pipe section in which is rotating a corrosion resistant PTFE / SS / other corrosion resistant wiper system with suitable rows of blades supported by suitable bearings. Wiped Film Evaporators give a high wiping frequency and therefore, an optimum renewal speed of the boundary layer, which are pre-requisites for thorough mixing of the liquid film and for high evaporation rates. The Thin Film Evaporators are forced against the evaporator wall by centrifugal force, and this can be varied via the speed of rotation of the drive, depending on the viscosity of the liquid.

Mixer Settler http://www.bvres.com/mixer-settler.htm http://www.bvres.com/mixer-settler.htm Fri, 05 Aug 2022 00:00:00 +0530 Mixer-Settler Extraction Unit The Mixer-settler system is fabricated and assembled in a compact modular design. The mixer as well as the settler are both integrated together instead of being separate entities. This allows the system to be compact and ideal for laboratory and R&D usage. A single stage of Mixer-Settler consists of a mixing zone and settler decanting zone connected to each other through a Weir zone. A brief description of the zones is as follows  :  Mixing System The Laboratory mixer consists of a special glass / SS (as per choice) mixing zone, suitable high-speed agitator and a variable speed drive. Besides providing an intimate dispersion the stirrer provides the necessary pumping action. This eliminates the need for external pumps and ensures a large interfacial area for mass transfer. The energy required to produce this dispersion will depend very much on the characteristics of the material and the system used (interfacial tension, viscosity, flow rates, etc). Between the mixing and separation zones, a weir is incorporated to prevent back mixing taking place and maintains the level of liquid in the mixing zone. Besides this, it also acts as a baffle to dampen the flow of liquid into the decanter (settler) for enhancing efficient phase separation. Settling System The settler comprises a horizontal cylindrical pipe which depending upon size may be one or more pipe sections. From the settler, the outlet of the heavy phase, is controlled by an overflow valve. The design of the settler will be influenced by the throughput of both phases and the material physical properties (density difference, viscosity, interfacial tension etc). Multi-Staging Mixer-Settlers Different stages can be connected to each other and the interconnecting pipelines can be done as per your required flow logic. The whole assembly would be controlled through a control panel consisting of suitable circuit breaker MCBs, Relays, digital controllers etc. Glass Equipment http://www.bvres.com/glass-equipment.htm http://www.bvres.com/glass-equipment.htm Wed, 03 Aug 2022 00:00:00 +0530 Coupling Flanges http://www.bvres.com/coupling-flanges.htm http://www.bvres.com/coupling-flanges.htm Fri, 05 Aug 2022 00:00:00 +0530 Keeping in-line with the globally accepted standards, the raw material used for production is of high-grade.

Sulphuric Acid Concentration Plant http://www.bvres.com/sulphuric-acid-concentration-plant.htm http://www.bvres.com/sulphuric-acid-concentration-plant.htm Fri, 05 Aug 2022 00:00:00 +0530 We have firmly positioned ourselves as one of the dependable Sulphuric Acid Plant Manufacturers and suppliers based in India. We deal in two types of Sulphuric Acid Chemical Plant that includes : Sulphuric Acid Concentration plant Sulphuric Acid Dilution Sulphuric Acid Concentration Plant Sulphuric acid is used in many processes in chemical plants, thus making spent acid quite diluted. Disposing of this spent acid becomes an environmental pollution problem besides a waste of precious resource. The diluted spent acid can be efficiently re-concentrated up to a maximum concentration of 96% (w/w) and reused in the main plant process, thus saving the environment and that too by improving the economical bottom line. Thus, sulphuric acid recovery or concentration plant is a fantastic option for high sulphuric acid users in process plants. Concentration of Sulphuric acid is mostly performed under vacuum in order to reduce the operating temperature, especially for high concentrations. We offer turnkey solutions right from know-how & technology, to supply, installation & commissioning. Our plant comprises of equipments wherin the wetted parts are made up of Borosilicate glass 3.3, Fluoropolymers (PTFE, PFA, FEP, PVDF, PP, etc), High Nickel alloys, Graphite & exotic metals (Ta, Ti, Nb, etc.). The plants can be totally automated by PLC or DCS based systems and even integrated with computers (SCADA etc). Sulphuric Acid Dilution Sulphuric acid is a heavy chemical and finds numerous applications in the industry. It is the product of ‘Contact Process’ and commercially available as 98.5% (w/w) H2SO4 or stronger in the form of oleum. However, many of the processes and applications utilizing sulphuric acid require weaker acid than this. As a result, dilution equipment is often necessary in order to meet the requirement for this weaker acid. During dilution, considerable heat is generated depending on the extent of dilution desired. The Integral heat of solution of sulphuric acid is plotted in fig.1. The heat liberated sometimes is sufficient to produce boiling of the acid and so, provision is made for the re-circulation of a portion of cooled dilute acid, thus ensuring working at controlled temperature. From the above it will be clear that intimate mixing and efficient heat transfer form the pre-requisites for sulphuric acid dilution unit to avoid excessive temperature and local heating and uniform product concentration. Process Description Metered quantity of sulphuric acid is introduced to a heat exchanger with re-circulation of water through a pump from the tank containing pre-determinant quantity of water. The turbulence created in the heat exchanger ensures both intimate mixing and efficient heat transfer. When desired strength of acid is reached, the contents of the tank are transferred to storage and fresh batch can be started again. Benefits of Industrial Sulphuric Acid Plant High product quality is guaranteed, as glass is completely inert to sulphuric acid Available in wide range of concentrations and capacities Simple and easy to operate Operational reliability due to maintenance free in working Corrosion Resistant Sulphuric Acid Dilution Plant http://www.bvres.com/sulphuric-acid-dilution-plant.htm http://www.bvres.com/sulphuric-acid-dilution-plant.htm Fri, 05 Aug 2022 00:00:00 +0530 Sulphuric acid is a heavy chemical and finds numerous applications in the industry.

If the acid concentration is lower than the azeotrope mixture, the acid can be concentrated only upto the azeotropic point. Further concentration needs special procedures. We have considered the most economical contemporary technology-“Extractive Rectification & Absorption Technology”. Extractive Rectification & Absorption Technology  As mentioned this is an economical technology and is presented in illustration below the azeotrope point is suppressed as best as possible and increases the relative volatility of HCl. The relative volatility may be impacted by change of the activity coefficients. This is achieved by addition of a third ingredient, the extractive agent, which displays strong hygroscopic properties. Conc. HCL & HCl gas is produced at the head of the extractive rectification column upon choice of an appropriate extraction agent. In the column the extraction agent is diluted with water, which is extracted in a selective fashion from the inflowing mixture. Subsequently, the extractive agent is recycled and newly fed into the extractive rectification process.    Sulphuric acid, and aqueous solutions of CaCl2 are appropriate extraction agents for the concentration of hydrochloric acid.
