Sulfur-containing gas emptying and desulfurizing device

Abstract

The invention is applicable to the technical field of chemical equipment, and provides a sulfur-containing gas emptying and desulfurizing device, which comprises a separator for removing liquid dropsentrained in emptying gas, a storage device for containing a desulfurizing agent and a plurality of desulfurizing areas for desulfurizing the emptying gas, which are sequentially arranged from bottomto top, and gas distributors are arranged in the storage device and the desulfurizing areas. Therefore, hydrogen sulfide in the emptying gas can be fully absorbed, the desulfurization effect of the emptying gas is improved, and the quality of the surrounding environment of an oil field is improved; the whole device is of a skid-mounted structure, the equipment manufacturing cost is low, emptying gas flows smoothly in the device, the safety is high, the desulfurizing agent is recycled, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a sulfur-containing gas venting and desulfurization device. Background technique [0002] At present, if the safety valve is vented during abnormal production in the crude oil processing station, or the gas in the equipment and pipeline is temporarily vented during maintenance, it will have certain adverse effects on the surrounding environment. In many low-sulfur old oilfields, the sulfur content gradually increases in the later stage of development, and the hydrogen sulfide content in the associated gas increases year by year, and the sulfur content is usually higher than 20mg / Nm 3 , the direct discharge will pose a threat to the health of crude oil station operators and surrounding personnel, and pollute the environment. [0003] At present, the state attaches great importance to the environmental protection around oilfields, and oilfield stations are not allowed t...

AI Technical Summary

Problems solved by technology

The use of torch combustion to discharge sulfur-containing gases occupies a small area, but the investment in equipment is high. It is difficult to operate the torch to detect the release of gas. The torch has a permanent light and the lit torch is likely to cause panic to the surrounding residents. The sulfur dioxide produced by the combustion is harmful to the environment. The environment is still polluted

[0004] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
