acid fume scrubber design

In Modutek’s fume scrubber design, the fumes pass over a wet packed bed. 2020 ProMinent Fluid Controls, Inc. All rights reserved. A wet scrubber is just one example of the many types of air pollution control technologies available. For Ammonia Scrubbers to meet these standards, a number of variables need to be reviewed including, but not limited to, concentration of the gas stream, other chemicals in the air stream, particulates, temperature and flow rate. They not only range in any size to meet ventilation systems needs but can also be constructed out of several types of plastic or metal. Chemical scrubbers can remove up to 99.5% of hydrogen sulfide and ammonia, even at high concentrations. Elimination of odors and chemical fumes protect the surrounding area, keeping parts and materials free of chemical residue that may effect the finish product. Wet Scrubbers – Removal of contaminants and particulates from a gas stream by passing the stream through a packed bed or venturi scrubber. ​All of our scrubber & ventilation air handling systems can be custom designed to fully integrate into your current facility and operating needs. Each concept design is carefully made to meet the specified space & safety requirements. Using this automatic control function the Chemical Feed is controlled by the pH or ORP Controller via one of two ways. The Acid Fume Separator (AFS) is a proprietary device that allows for direct venting of an acid tank located inside a mechanical room. For wet scrubbers used to control acid gas emissions, monitoring scrubber liquid pH is an adequate surrogate for scrubber liquid outlet concentration. Each Vanaire Fume Scrubber is designed and manufactured according to your facility’s specific conditions and desired efficiency. The ammonia reacts with the sulfuric acid to form ammonium sulfate, a soluble, non-volatile salt, which is removed from the scrubber effluent through the overflow. interested students in environmental engineering. Cross Flow Scrubber with Fan and Common Base. These calculations, coupled with our knowledge of the fumes being emitted by the process, allow Mech-Chem to assist in the Permitting of the Air Discharge. We are able to fabricate panels that meet the explosion proof rating. Waste fume scrubbers suitable for chemical producers, metal finishing semi-conductor manufacturing, food industry, and other operations generating fumes and gases. When the set point is reached the chemistry is automatically metered into the reservoir to ensure proper treatment of the gas stream. Fume Scrubbers Controls—Operator Interface copyright 4 shows a special design that was developed to remove H 2 S from a sour-water stripper overhead stream that also contains Treated gas Spent caustic (NaSH) Exchanger Inlet sour gas Makeup caustic Weak caustic feed Strong caustic feed Makeup water Fig. Exhaust gas flow rate affects the L/G ratio, which is a key design parameter for wet scrubbers. Mech-Chem offers duct work and fittings manufactured from several different types of material all capable of meeting and being field labeled as FM Approved. Gas flow rate. Why are chemical scrubbers needed? Customized to your specific need Eliminate odors, acids, chemicals and NOx fumes with waste fume vent scrubbers from the corrosives specialists at Hazarsolve. In a wet scrubber a fan or blower system is used to draw chemical vapors through ductwork and into the scrubber tower. by . Mech-Chem designs builds and installs Scrubbers to handle all types of chemical fumes. Also, butterfly valves can be placed in the Ventilation Duct in order to restrict or shut off air flow if necessary. ), Removal and Replacement of Strainers, Spray Nozzles, Packing, Mist Eliminator, Blower Belts, and any other wear items. Custom fume hoods & manifold systems are designed to extract hazardous airflow fumes away from the working area, providing a safe & healthy environment. ​Venturi scrubbers are capable of handling airborne particulates in exhaust streams with high efficiency. The CFM of the Push Air is dependent on the width of the tank, chemistry in the tank, operating temperature of the tanks solution, size of the part, etc. These calculation and knowledge of the fumes being emitted by the process allows Mech-Chem to assist in the permitting of the air discharge. Our knowledge of processes, emission rates of chemical baths and efficiencies of scrubbers allows us to help facilities layout the best location and required design for their air emissions Stack. ​​A high efficiency wet scrubber is required to prepare NOx fumes for emission to the atmosphere. ​Mech-Chem designs, fabricates and installs Chrome Scrubbers for all types of Chrome applications including Anodizing Chrome, Chrome Etching, Chrome Manufacturing, Chrome Plating, Chrome Stripping, Decorative Chrome Plating and Hard Chrome Plating. Ammonia is an irritant to eyes, nose and throat and even poisonous at higher levels. The chemical vapors are drawn into the bottom of the tower and pass up through a packed bed chamber. For wet scrubbers used to control acid gas emissions, monitoring scrubber liquid pH is an adequate surrogate for scrubber liquid outlet concentration.
