Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0026] Such as Figure 1~2 The shown embodiment of the present invention is a sulfur-containing oil gas recovery device, including: a desulfurization device, a condensation device, and a catalytic oxidation device 3 connected in sequence; the desulfurization device contains a desulfurizer for absorbing H in the oil gas 2 S; the condensing device includes a cold box 21, which is used to cool part of the oil and gas to obtain an oil-water mixture, and the uncondensed oil and gas enters the catalytic oxidation device 3 through the pipeline and is released after combustion.

[0027] The adsorption device includes two switching desulfurization towers, which are divided into a first desulfurization t...

Abstract

The invention provides a sulfur-containing oil gas recovery device and a process. The device comprises a desulfurization device, a condensation device and a catalytic oxidation device, which are connected in sequence; the desulfurization device contains a desulfurization agent for absorbing H2S in the oil gas; the condensation device comprises a cold tank used to cool part of the oil gas to obtainan oil-water mixture; and the uncondensed oil gas enters the catalytic oxidation device through a pipeline, and is released after combustion. The device and process are used for treating the sulfur components in exhaust gas to meet the requirements of the standard discharge and recover useful materials; and the process can greatly reduce the operation energy consumption and can meet the long-termuninterrupted operation.

Description

technical field [0001] The invention relates to the field of oil gas recovery, in particular to a sulfur-containing oil gas recovery device. Background technique [0002] Industrial waste gas refers to the general term for all kinds of pollutant gases that are discharged into the air during fuel combustion and production processes in the factory area. The exhaust gas often contains H 2 S, H 2 S enters the human body through the respiratory tract through different routes, some of which directly cause harm, and some have a cumulative effect, which will seriously endanger human health. [0003] Therefore, industrial waste gas cannot be directly discharged into the atmosphere. Waste gas treatment must be carried out, and it can only be discharged after reaching the emission standard. In the treatment of gas, the absorption method uses the characteristics that the organic compounds in the waste gas can be miscible with most oil substances, and the high boiling point is commonly...
