Embodiment Construction

[0033] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0034] The circulation type crude oil storage tank oil gas vacuum adsorption recovery system of the present invention comprises: crude oil storage tank 14, vacuum desulfurization device 5, 7, 8, adsorption tank 9, 10, vacuum pump C 11, absorbent treatment device 2, 3, 6 and The absorption tower 12, the vacuum desulfurization device includes a vacuum pump A and a desulfurization tank, and the absorbent treatment device includes a heater 2, a cooling tower 3 and a vacuum pump B6, and the crude oil stored in the crude oil storage tank 14 passes through the The oil supply pipeline flows through the heater 2, and after being moderately heated by the heater 2, the viscosity of the crude oil is reduced, and then enters the cooling tower 3, where the gas and liquid are separated after being condensed in the cooling tower 3, and the gaseous light ...

Abstract

The invention provides a circulating type oil-gas vacuum adsorption and recovery system comprising a crude-oil storage tank, comprising the crude-oil storage tank, a vacuum desulfurization device, an adsorption tank, a vacuum pump, an absorbent treating device and an absorption tower, wherein the absorbent treating device treats crude oil pumped from the crude-oil storage tank into lean gasoline;volatile oil gas of the crude-oil storage tank enters the vacuum desulfurization device and then enters the adsorption tank for adsorption and recovery after desorption and desulfurization; standard air is exhausted into atmosphere from the upper end of the adsorption tank, and nonstandard tail gas reenters the adsorption tank for circulating adsorption and recovery; the vacuum pump is used for carrying out vacuum desorption and regeneration on the adsorption tank with saturated adsorption; and desorbed high-concentration oil gas enters the absorption tower, and is absorbed by the lean gasoline body from the absorbent treating device, and the rich gasoline after absorption returns to the crude-oil storage tank. The circulating type oil-gas vacuum adsorption and recovery system is convenient and simple, volatile oil gas is absorbed and recovered by fully utilizing the self characteristic of the crude oil, additional equipment and resources do not need to be added, and the secondary pollution is not caused as well.

Description

technical field [0001] The invention relates to an oil gas adsorption recovery system, in particular to an oil gas adsorption recovery system for a crude oil storage tank. Background technique [0002] Crude oil from extraction to refinery processing, and refined oil from refinery output to end-user consumption usually go through several storage, loading and unloading processes. During these processes, due to factors such as temperature, air pressure, and volume changes of the gas-liquid phase of the oil container, some oil and gas will volatilize into the atmosphere, resulting in loss of oil and gas. From the perspective of oil and gas recovery, oil and gas loss can be roughly divided into three parts. One is the oil and gas breathing loss in the storage tank, which is mainly concentrated in crude oil transfer stations, refineries, oil depots, etc.; the other is transportation tools such as trains, cars, and ships. The oil and gas loss caused by the loading and unloading p...
