Upstroke reaction steam stripping separator and hydrogenation method

Abstract

The invention discloses an upstroke reaction steam stripping separator and a hydrogenation method. The reaction steam stripping separator comprises a reaction zone and a mass transfer separation zone, the reaction zone and the mass transfer separation zone are arranged in a same container shell body, the reaction zone is arranged in the lower part, the mass transfer separation zone is arranged in the upper part, an annular middle spacer plate and a manhole passage are arranged between the reaction zone and the mass transfer separation zone, an annular space is formed by the middle spacer plate, manhole passage and container shell body, and the annular space is closed at the lower end and is provided with an opening at the upper end, and the mass transfer separation zone is in the annular space. The method is as follows: raw material oil and a part of hydrogen enter from the bottom of the upstroke reaction steam stripping separator, the other part of the hydrogen is injected from reaction zone catalyst bed interlamination for hydrogenation reaction in a reaction zone, a gas phase product is collected at the top, and a liquid phase product is collected at the side wall. According to the upstroke reaction steam stripping separator and the hydrogenation method, equipment investment and occupied area are reduced, the problem that many leakage points are produced for the reason that two independent equipment are connected by pipelines is reduced, and the device safety is improved.

Description

technical field [0001] The invention relates to the field of hydrogenation reaction, and more particularly, relates to an upward reaction stripping separator and a hydrogenation method. Background technique [0002] In the field of petrochemical hydrogenation, independent fixed-bed reactors and stripper mass transfer separators are often installed. The fixed-bed reactors usually adopt a downward type, that is, the raw materials enter from the top of the reactor, and the reaction products flow out from the bottom of the reactor. The reaction product then enters a separate stripping tower for stripping and mass transfer separation of gas phase products and liquid phase products. [0003] When adopting the scheme of the ascending reactor, the raw material enters from the bottom of the reactor, and the reaction product flows out from the top of the reactor. Since the flow direction of the gas in the upward reactor is consistent with the diffusion direction of the gas, the possi...

AI Technical Summary

Problems solved by technology

[0004] However, at present, the upward reactor and the stripper mass transfer separator are two independent devices, and the equipment investment and floor space are large, and there are many leakage points caused by the connection between the devices, which is likely to cause safety hazards
