Sulfur-bearing oil and gas mixture recovery process and device

Abstract

Disclosed are a sulfur-bearing oil and gas mixture recovery process and a device utilizing the same. The sulfur-bearing oil and gas mixture recovery process includes: feeding sulfur-bearing oil and gas mixture into an adsorption tower and removing and adsorbing oil in gas in the mixture by adsorbent in the absorption tower; feeding sulfur-bearing mixture without oil and gas into a desulfurizing tower, removing sulfide mixed in the mixture further while exhausting cleaned gas from the top of the desulfurizing tower after the sulfide is removed; desorbing the adsorbent adsorbing oil and gas components in the adsorption tower under action of a vacuum pump, leading the oil and gas components which are desorbed into an absorbing tower, recovering oil and gas under action of the absorbent in the absorbing tower, feeding rich oil which is formed after the absorbent absorbing the oil and gas components into an oil storage tank to be recovered, while returning a small quantity of oil and gas which are not absorbed to the adsorption tower to be further adsorbed circularly. By the aid of the sulfur-bearing oil and gas mixture recovery process and the device utilizing the same, oil, gas and sulfide mixed in the sulfur-bearing oil and gas mixture can be removed, oil and gas are recovered, and meanwhile the difficult problem that environmental pollution caused by sulfide is solved. Accordingly, the sulfur-bearing oil and gas mixture recovery process and the device utilizing the same have the advantages of energy economization and environmental protection.

Description

technical field [0001] The present invention relates to the technical field of energy conservation and environmental protection, in particular to a method and device for recovering sulfur-containing oil-gas mixtures, which are mainly used for recovering sulfur-containing oil-gas mixtures in the processes of gathering, refining, storage, transportation and sales of petroleum and its products Utilize, remove the sulfide in it at the same time. Background technique [0002] Petroleum and its products contain a considerable amount of light components such as CH 4 、C 2 h 6 、C 3 h 8 Wait. The information provided by the oil field shows that the amount of volatile gas in crude oil is quite huge, and the total annual volatile gas in the country is 1×109m 3 The above is roughly equivalent to 10% to 20% of the total annual natural gas exploitation in the country. If all these crude oil volatile gases can be recycled, they can be used by more than 1 million families for more tha...
