Embodiment Construction
[0020] Below in conjunction with embodiment the present invention is described in further detail, and the course of work of the present embodiment is as follows:
[0021] The desulfurization and recovery process of the crude oil escape gas is shown in the figure. The escape gas passes through the gas-liquid separator 1, most of the water and the alkane components below C4 (black) condense into a liquid state, and is discharged through the lower end of the oil-gas separator 1; The volatile gas is introduced into the hydrogen sulfide adsorption tower 2 from the upper end, and the hydrogen sulfide gas is adsorbed by activated carbon; the remaining light gas is introduced into the main activated carbon fiber adsorption tower 5 or the auxiliary activated carbon fiber adsorption tower 6 by the blower 3 and is adsorbed by the activated carbon fiber. The air is vented to the atmosphere through the flame arrester 7 . During desorption, the adsorbed methyl ethyl propane is depressurized...

The invention discloses an oil gas recovery reactor for removing hydrogen sulfide gas from crude oil vapor. Specifically, crude oil vapor is firstly subjected to oil-gas separation by an oil-gas separator, and the separated residual oil is discharged from the lower end of the oil-gas separator; the separated vapor passes a bed of iron oxide desulfurizer, and hydrogen sulfide is absorbed by iron oxide; the desulfurized vapor then passes an active carbon fiber adsorption bed and absorbed by active carbon fiber; finally a desorption gas is admitted to desorb the recovered vapor component. The recovery reactor of the invention has large desulfurization capacity, good selective adsorption, low energy consumption, high recovery efficiency, simple technological process and long service life. In addition, the reactor not only reduces the emission and pollution of hydrogen sulfide gas in crude oil vapor of oil fields but also recovers the volatilized oil gas.
Description
Technical field: [0001] The invention relates to an oil gas recovery reactor device for removing hydrogen sulfide gas in crude oil volatile gas, in particular to an oil gas recovery reactor device for removing hydrogen sulfide gas in crude oil volatile gas by an activated carbon fiber adsorption method. Background technique: [0002] Crude oil storage tanks are usually distributed near oil wells, with scattered locations and relatively few operators, and the requirements for fire protection and anti-virus are very high. Crude oil and light oil products contain a large amount of light hydrocarbon components, which are highly volatile, and will inevitably be A portion of the liquid hydrocarbon components vaporize and escape into the atmosphere. According to research and calculation, the oil evaporation loss caused by crude oil volatile gas is very huge every year, and the oil evaporation loss will bring great harm. First, it causes an extreme waste of energy. According to the...
