Problems solved by technology

[0022] The purpose of the present invention is to provide a high-sulfur crude oil gas recovery process to solve the problem of penetrating sulfur in the desulfurization tower due to the high concentration of sulfide entering the desulfurization tower in the existing oil gas recovery process. It is a technical problem that the sulfur content in the desulfurized oil and gas is difficult to meet the standard due to the low capacity and poor desulfurization effect.
[0023] Another object of the present invention is to provide an oil gas recovery system for the above-mentioned high-sulfur crude oil gas recovery process, to solve the problem of high concentration and variety of sulfides entering the desulfurization tower in the existing oil gas recovery process. The composition is relatively complex, which leads to a low penetration sulfur capacity of the desulfurization tower and a poor desulfurization effect, which makes it difficult for the sulfur content in the desulfurized oil and gas to meet the technical problem

Abstract

The present invention provides a high sulfur crude oil oil-gas recovery technology and oil-gas recovery system. The oil-gas recovery technology includes the following steps: a. high sulfur crude oil oil-gas is compressed, the compressed oil-gas is cooled, then gas and liquid separation is performed, and the separated liquid is collected; b, the separated oil-gas of the step a is condensed, then gas and liquid separation is performed, and the separated liquid is collected; c, the separated oil-gas of the step b is introduced into an activated carbon adsorption device, and is desulfurized, and desorption and collection of hydrocarbons in the activated carbon adsorption device are performed. According to the high sulfur crude oil oil-gas recovery technology, most of sulfides and hydrocarbons are condensed into liquid in the condensation processing process, species and quantity of sulfides entering into a desulfurization tower are less, and the composition is simple, so that breakthrough sulfur capacity of the desulfurization tower is high, the desulfurization effect is better, and when the sulfur content in the desulfurized oil-gas is very easy to meet.

Description

technical field [0001] The invention relates to the technical field of crude oil gas recovery, in particular to a high-sulfur crude oil gas recovery process and an oil gas recovery system. Background technique [0002] Crude oil volatiles are mainly hydrocarbons and sulfides, hydrocarbons include CH 4 、C 2 h 6 、C 3 h 8 etc., are flammable gases; sulfides include H 2 S, carbonyl sulfide, mercaptan, thioether, thiophene, disulfide compound, etc. Arbitrary discharge of crude oil volatiles will not only bring environmental pollution, but also directly endanger the living environment of human beings. Since most light oil products are volatile, flammable and explosive substances, they are easy to gather, form an explosive mixture with air, and then settle in depressions or pipe trenches, which are prone to explosion or fire accidents in case of fire, resulting in loss of life and property. huge loss. Due to the wide range of oil-gas explosion limit and the wide range of oi...
