Abstract

The invention provides an apparatus for treating oil refinery purge gas by adopting active carbon. The apparatus for treating oil refinery purge gas by adopting active carbon comprises a closed reaction tower, and the middle in the body of the tower is fully filled with the active carbon; the reaction tower is divided into an upper part and a lower part by an inner bin; the lower part of the reaction tower is connected with an air feeding tube, a pure gas feeding tube and a liquid discharging tube; the upper part of the reaction tower is connected with an air discharging tube, a combustible gas discharging tube and a liquid feeding tube respectively; the air feeding tube is also connected with a heating and pressurizing device; the combustible gas discharging tube is connected with a collecting device; the liquid discharging tube is connected with a recovering device; and a stirring device is arranged at the bottom end of the lower part of the reaction tower. The apparatus has the advantages of high hydrogen sulfide treatment rate, recovery of elemental sulfur, no consumption of other materials, and high economic efficiency.

Description

technical field [0001] The invention relates to a treatment device for exhaust gas in an oil refinery, in particular to a device for exhaust gas in an oil refinery. Background technique [0002] The sour waste gas from the refinery contains 60-80% hydrogen sulfide, 3-10% carbon dioxide and some combustible gases, such as ethane, methane, propylene, propane, ethylene and carbon monoxide. Among them, the content of hydrogen sulfide is relatively high, and hydrogen sulfide is highly toxic and polluting. In the existing treatment methods for acid waste gas from refineries, direct torch combustion is usually used to treat the generated sulfur dioxide or directly absorb lye. These methods cost a lot and waste a lot of resources. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned technologies, the present invention provides a device for treating refinery exhaust gas with activated carbon. The device for treating refinery exhaust gas with activa...
