The Acid Fume Separator (AFS) is a proprietary device that allows for direct venting of an acid tank located inside a mechanical room. The second stage is typically washed down every 24 hours. In every application, AAT, Inc. considers all factors in selecting the optimum design for your hydrochloric acid scrubber. Tubing, depending on location and length of run, is double contained by running it through a clear PVC Pipe. We specify materials of construction, design parameters (such as explosion proof), as well as equipment size for the entire chemical process. Gas flow rate. Mech-Chem engineers, designs and manufactures high quality Ammonia Scrubbers that operate at or above the required removal efficiency. Exhaust gas flow rate affects the L/G ratio, which is a key design parameter for wet scrubbers. The Door and Back Panel Layout, as well as the Wiring Schematics, are designed to meet the requirements of the Facility. Acid processing industries often generate fumes that need to be neutralized and reduced to a harmless vapor before discharge to the atmosphere. Dust collectors are featured with removal filter bag cartridges allowing for continuous operation without the need of operation shutdown. Physical adsorption relies on inter-molecular forces while chemical adsorption involves the formation of chemical bonds. The flexibility of gas treatment procedures in these machines is provided by the possibility of loading reagents with desired chemical properties into the atomizing section. The Acid Fume Separator (AFS) is a proprietary device that allows for direct venting of an acid tank located inside a mechanical room.

We specialize in handling all types of acid fumes and hazardous/corrosive streams, to ensure our clients have a neutralized & contaminant free air stream during emission. A Chrome Scrubber is also fabricated so each of the three mesh pad stages drains into its own reservoir. Degassing Towers – Removal of the acid forming carbon dioxide from water. Our range of services are designed to minimize a variety of airborne pollutants and regulated emissions such as acid gases, fumes, corrosive or hazardous streams, air particulates and other organic odors. It is hoped that the result of this paper will be to provide an easy to follow manual on wet scrubber design suitable for use . Acid Fume extraction system Designed for Zero Discharge and Clean Air Emission Acid fume capture and abatement is a significant aspect in every hot dip galvanizing plant. interested students in environmental engineering. Venturi scrubbers are capable of handling airborne particulates in exhaust streams with high efficiency. Inside the tank are water spray nozzles. Gas flow rate. Also, butterfly valves can be placed in the Ventilation Duct in order to restrict or shut off air flow if necessary. 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. The fumes percolate up and through the scrubbing solution, then vent out of the top of the scrubber system. Emitted from a variety of sources, including: boilers, catalytic oxidizers for halogenated solvents, storage tank vents, and various chemical processes. Customized to your specific need Eliminate odors, acids, chemicals and NOx fumes with waste fume vent scrubbers from the corrosives specialists at Hazarsolve. Increasing the static pressure in the Scrubber, or raising the flow rate of the Scrubber in a process area that has a lack of proper make-up air, will not rectify the situation and in fact will only increase the problem. Chromic Acid Fume Scrubber — Multiple Stage Design Emissions from chrome plating and chromic acid anodizing operations produce hexavalent chrome mist that cannot be effectively removed in a conventional packed tower scrubber. We are able to fabricate panels that meet the explosion proof rating. Cross Flow Scrubber with Fan and Common Base. One of the most efficient, economical and low maintenance ways to scrub acid fumes is with a Wet “Packed Bed” Scrubber. The proprietary reagent will change from white to pink when reagent is no longer effective. Scrubbers can be designed in many different sizes, styles, and materials of construction based on your facility's chemical emissions. Mech-Chem offers engineering, design, fabrication, and installation services for all air quality handling equipment & systems. All scrubbers can be designed vertically or horizontally to accommodate facility floor space or height requirements. the component in the liquid and lowering of the absorption gradient. The majority of scrubbers function using adsorption, which involves the contact of a gas stream with an aqueous solution, due to the fact that the Chrome exists in the mist droplets, and not as a gas, the adsorption method is not effective. If the storage tank is filled using a mechanical pump, then the design capacity of the treatment equipment (scrubber) is simply equivalent to the volume of the displaced gas as the tank is being filled. The Panels also have all the needed power requirements and controls such as fuses, motor starters, overloads, step down (480V to 120V) transformers, 24 Volt DC Power Supply and more.
