Desulfuration equipment for tank top device, and desulphurization production technology

Abstract

The invention relates to a hydrogen sulfide removing technological scheme, and specifically relates to desulfuration equipment for a tank top device, and a desulphurization production technology. According to the desulfuration equipment, the top of an oil storage tank is provided with a spray nozzle; the spray nozzle is connected to a medicine feeding outlet via a pipeline; the medicine feeding outlet is connected to an outlet end of a medicine feeding pump; an inlet end of the medicine feeding pump is connected to the bottom of a medicine storage tank via a digital control valve; the bottom of the medicine storage tank is connected to a blowoff valve and an inlet end of a circulating pump; an outlet end of the circulating pump is respectively connected to the middle part of the medicine storage tank and an outlet end of a water inflowing medicine valve; the outlet end of the water inflowing medicine valve is connected to the top of the medicine storage tank; a hydrogen sulfide sensor is arranged on the top of the oil storage tank, and is connected to a host controller via a signal cable; and the controller is connected to switching circuits of the medicine feeding pump respectively. The desulfuration equipment and the desulphurization production technology are capable of avoiding conflicts of desulfuration safe production and cost control.

Description

[0001] technical field [0002] This patent relates to a hydrogen sulfide removal technical solution, specifically a tank top desulfurization equipment and a desulfurization production process. [0003] Background technique [0004] In the existing crude oil production, there is an oil storage link, because the crude oil contains hydrogen sulfide, which may volatilize and transfer to the working space through the tiny gaps in the equipment, causing the danger of personnel poisoning. However, the current method is to directly add desulfurizer to pipelines and oil tanks. The amount of desulfurizer is determined by the amount of crude oil, resulting in a very large amount of desulfurizer. However, the hydrogen sulfide content of actual crude oil varies greatly, and when the hydrogen sulfide content is low Under the situation that existing technology just causes the increase of production cost.

[0004] In the existing crude oil production, there is an oil storage link, because the crude oil contains hydrogen sulfide, which may volatilize and transfer to the working space through the tiny gaps in the equipment, causing the danger of personnel poisoning

However, the current method is to directly add desulfurizer to pipelines and oil tanks. The amount of desulfurizer is determined by the amount of crude oil, resulting in a very large amount of desulfurizer. However, the hydrogen sulfide content of actual crude oil varies greatly, and when the hydrogen sulfide content is low In the case of existing technology, the production cost increases
