Modified PSA

process captures VOCs from variable concentration vent emission streams.

Granular activated-carbon adsorbs VOCs from air and other vapor streams.

Vacuum-regenerated activated-carbon vapor recovery system controls VOC vapors from loading operations.

Process removes small amounts of acid, basic, or organic vapors into a liquid by absorption with and without chemical reaction.

Membrane separation with proven condensation and compression techniques removes select organic compounds.

Catalytic solvent abatement process treats exhaust gases containing chlorinated hydrocarbons and is suitable for PVC facility.

A packed-bed reactor destroys hazardous organic fumes by oxidation. This process can be used on chlorinated hydrocarbons also.

Combination of fixed-carbon-bed adsorption and thermal oxidation concentrates and oxidizes low-VOC concentration streams.

Catalytic oxidation system handles phthalic anhydride and pure terephthalic acid exhaust streams.

This catalytic process removes VOCs and solvents from exhaust air. The catalyst is poison-resistant and trouble-free.

SCR process controls NOx emissions with ammonia injection. Cost: $20-90/kw. Temperature: 290-595°C.

Catalytic conversion of NOx and SOx uses ammonia injection. Highly efficient removal of SO2.

Ammonia injection controls and reduces NOx emissions.
