Mobile Gas Absorber Sigma offers mobile effluent gas absorbers, which are an all glass assembly for Laboratory scale operations. The total assembly is mounted on stainless steel support structure and is skid mounted for maneuverability. Mobile Gas Absorbers suit the special needs of hazardous waste gas scrubbing in Chemical, Mining, Pulp & Paper, Petro Chemicals, Pharmaceuticals and Drug Manufacturing. Mobile gas absorbers are packed column or falling film type absorber units with pump - set, piping etc. Used for acid gas removal from hazardous by products generated during reaction study in laboratories. Salient Features of Mobile Gas Absorber Simple Design Ideal for Scrubbing exhaust from small scale Chemical Plants Suitable for air & exhaust clean up Ideal for studies and scale up of gas scrubber systems. HCL Gas Adiabatic Absorbers The Hydrogen Chloride gas produced as a by product can be economically processed into Hydro - Chloric Acid by simple Absorption. Adiabatic Absorption is the most effective means of production of Hydro - Chloric Acid solution. Under normal operating conditions Hydro Chloric Acid Solution of 30% - 31% strength can be obtained. These absorbers operate, as the name implies, without any heat input into the reaction zone. The gas loading should in no case fall below 50% of the design maximum for adiabatic absorption column to be most effective means of absorption. In this process HCL - Gas is absorbed by fresh water flowing down the column . The heat generated by this reaction vapourises approximately 30% of the water that rises to the head of the column with non - soluble components of the gas stream. Hydrogen Chloride streams containing air, water vapour & non - condensable are condensed / absorbed within the column and are returned together with the make up water to the bottom of the column through several packed sections and are passed through heat exchangers for dissicipatcing the heat of absorption before storage. The acid out let temperature is 45° C to 50°. Falling Film Absorbers In Falling Film Absorbers gas to be absorbed enters at the top of FFA and flows co-currently with absorbent liquid coming from storage tank by pump. Heat of solution released as a result of the absorption process is removed by the cooling water flowing in the shell - side of the falling film unit. Thus noxious gas absorption is effected at lower temperatures enabling a higher absorption rate than adiabatic absorption towers. The absorbed gas leaves at the bottom of FFA at a very low temperature for storage and disposal. The un-absorbed gas and any inert gases also leave via vent at the bottom of FFA and enter the venturi scrubber or bottom of tail gas tower scrubber as is shown in the figure. Falling film absorbers can be used for absorption of gases like HCl/Cl2/So2/NOX/HBr - where higher efficiencies of absorption are required. Salient Features : No moving parts. Ease of operation No maintenance Can handle very large gas flow rates as well variable gas flow rates Very less area required for installation. |
