CGS Packed Bed Tower Gas Absorbers

CGS' PACKED BED ABSORBERS rely on the diffusion of the polluting gases or fumes through the carrier gas to reach the surface of the scrub liquor. State of the art packing media provides the required surface area for intimate contact to achieve the highest efficiency. Upon contacting the liquor, the pollutants are absorbed into the liquor.

CGS' GAS ABSORBERS are designed to absorb SO2, Cl2, ClO2, HCl, HF, H2S, TRS, NH3, Amines, CH3OH, C2H5OH, CH3COOH, C6H5OH, and other VOC's and gaseous pollutants. CGS can supply a complete system for your absorption, cooling, condensing, stripping or odor control needs. For applications where dust removal is required prior to gas absorption, CGS' multiventuri or conventional Venturi Scrubber is included. For high temperature applications, CGS' prequencher section is included, incorporating a liquid seal type isolation/expansion joint. The system can incorporate a chimney tray to separate dust and gas absorption liquid recycle loops to avoid build-up problems and maximize efficiency with minimum downtime. Various materials of construction are available to accommodate hot, corrosive, erosive and dusty services.

In a VERTICAL PACKED BED TOWER, the pollutant laden gas enters the tower radially near the bottom and is directed upwards through the packed bed. Liquor is distributed on top of the packed bed by a spray header and is dispersed on the packing media. Intimate contact between the liquid and the gas takes place in this area in a counter current mode resulting in the absorption of the pollutants into the liquor. The cleaned gas passes through a mist eliminator, which removes most of its entrained liquid droplets, before exiting the tower. The scrub liquor flows to the integral or external sump and is recycled, in part or in whole, back to the top of the tower.

In a CROSS FLOW TOWER, the horizontal gas flow and the downward liquid flow are perpendicular to each other. This configuration is ideal when height restrictions exist. Its horizontal profile allows access from one level.
