Pressure-stock-type two-stage double-agent desulfurization device and application method thereof

Abstract

The invention relates to the field of oil exploitation, and discloses a pressure-stock-type two-stage double-agent desulfurization device and an application method thereof. The device comprises a primary desulfurization tank and a secondary desulfurization tank. Gas pressure dividers and gas dispersers are arranged on the bottoms of the inner cavities of the primary and secondary desulfurization tanks. Gas deflection collection hoods and gas-liquid separators are arranged on the tops of the desulfurization tanks. A partial pressure control valve is arranged on a gas route before the primary desulfurization rank. A pressure-stock control valve is arranged between the primary and secondary desulfurization tanks. With the device, a hydrogen sulfide component in ground oil storage square can associated gas can be subjected to dynamic desulfurization treatment progressively with pressure, with the process flow of the device, while production is not stopped. Therefore, hydrogen sulfide content in the oil storage square cans can reach related standards, corrosion to delivery equipment can be reduced, injury caused by hydrogen sulfide is prevented, and personal safety of staffs is improved.

Description

technical field [0001] The invention relates to the field of petroleum exploitation, in particular to a backlog type two-stage double-preparation desulfurization device and a use method thereof. Background technique [0002] At present, in the process of crude oil extraction, the hydrogen sulfide component in the associated gas of the oil layer corrodes the transportation equipment, which seriously shortens the service period of the transportation equipment, and at the same time, hydrogen sulfide also seriously endangers the personal safety of the staff. At the same time, due to the lag in the construction of ground transmission pipelines, most well site producers currently place oil storage square tanks on the well site to temporarily store the crude oil produced by the oil well, and then transfer it to the centralized processing station by car, which leads to A large amount of hydrogen sulfide gas accumulates in the oil storage square tank, which causes greater harm to the...

Problems solved by technology

[0002] At present, in the process of crude oil extraction, the hydrogen sulfide component in the associated gas of the oil layer corrodes the transportation equipment, which seriously shortens the service period of the transportation equipment, and at the same time, hydrogen sulfide also seriously endangers the personal safety of the staff.

At the same time, due to the lag in the construction of ground transmission pipelines, most well site producers currently place oil storage square tanks on the well site to temporarily store the crude oil produced by the oil well, and then transfer it to the centralized processing station by car, which leads to A large amount of hydrogen sulfide gas accumulates in the oil storage square tank, which causes greater harm to the transportation equipment

The existing technology to solve this problem is to add desulfurizer into the tank on the roof of the square oil storage tank at the well site, but the effect is extremely unsatisfactory, and it will cause corrosion and damage to the square oil storage tank; at the same time, it will endanger the personal safety of the personnel on the production site and Extremely unenvironmentally friendly, thus failing to fundamentally solve the hazards of hydrogen sulfide components to conveying equipment

[0003] At present, there is no relatively complete, simple and reliable equipment that can meet the site placement conditions and working environment under dynamic conditions, and protect oil storage equipment on a scale of quantitative preparations; at the same time, ensure the effective neutralization of hydrogen sulfide components and cleared to achieve industry-leading security levels
