Improvement of the adsorption-absorption vapor recovery unit for cleaning the gas-air mixture from volatile organic compounds and hydrogen sulfide when loading naphtha on marine tankers

The article proposes the improvement of adsorption and absorption plants for recovery naphtha vapors through use a sulfur compounds purification unit. This unit allows you to remove environmentally hazardous components from vapors, which adversely affect filters, without increasing temperature significant pressure drop gas-air mixture. relevance study is due fact that marine terminals are objects emissions hydrocarbons compounds. Intensive evaporation during filling process leads air pollution loss valuable product. Vapor units with desulfurization designed solve problem, however, their implementation at loading facilities requires installation additional flow stimulators and, as rule, electricity consumption. main purpose was find ways improve environmental safety vapor existing sea tanker facilities, taking into account current level technical equipment. It established proposed desulphurization makes it possible expect reduction in energy consumption absence (gas blowers), well an increase operation filters by 35-45%. effectiveness modeling low-pressure gas hydrogen sulfide has been confirmed studies on laboratory including reactor. Purification using chelated iron complex ensures conversion sulfur, while residual content can be reduced less than 1 ppm. catalytic disk film apparatus purify mixture impurities.
