VOC Control System

What Are VOC’S ? : Volatile Organic Compounds ( VOC ), are generated in streams where oils are present in refinery and petrochemical effluents or streams. These normally consist of BTEX (Benzenes, Toluenes, Xylenes etc.), and other organic compounds which add to the odor and are now required to be controlled whereas they were previously vented into the atmosphere.
VOC Control : All VOC generating points such as oil sumps, storage tanks for slop and feed oils, separator tanks like API’S, TPI’s, DAF systems, etc. need to be fitted with the VOC control system. This control may be either by Carbon adsorption and subsequent desorption, or by use of thermal oxidizer systems, to ensure that the vapors escaping from these units are controlled to contain the VOC’s.
Carbon Adsorption : This is the easiest and most basic form of VOC control, wherein a particular grade of Carbon is chosen based on tests on the streams and on experience. The VOC’s are then passed through the Carbon bed to adsorb them and to ensure that the vapors coming out are harmless to the atmosphere. This is carried out in Carbon canisters or in Tanks, depending on the flow and the site conditions. Basically, a Fixed Bed or a Fluidized Bed option is possible.
Thermal Oxidation : Popular for higher VOC concentrations, thermal oxidation will combust the VOC gases to achieve very high levels of purity of the vented air. Obvious advantages are non-replacement of the spent carbon bed.
