Embodiment 1

[0051] Taking a hydrocracking as an example to illustrate, the plant scale is 2 million tons per year, the raw materials are reduced second-line straight-run wax oil and coking wax oil, and the production plan is a one-pass process for prolific jet fuel.

[0052] The gas-liquid separation of the reaction product adopts the present technology invention, and the specific process is as follows figure 1 shown. The hydrogenation reaction product after heat exchange enters the hot high pressure separator for gas-liquid separation. The cold mid-separate gas enters the cold high-pressure separator after further cooling in the hot high-separate gas phase cooler. The gas phase of the cold high pressure separator enters the circulating hydrogen desulfurization and compression system as circulating hydrogen.

[0053] The liquid phase of the hot high pressure separator (referred to as hot high oil separation) enters the hot medium pressure separator after decompression. The gas phase af...

Abstract

The invention discloses a gas-liquid separation process of a hydrogenation reaction product. On the basis of the existing hydrocracking product separation process, the present invention changes the outlet with a large amount of dissolved hydrogen due to the process of the hot and high pressure separator by setting a hot medium pressure separator and a cold medium pressure separator, so that a large amount of dissolved hydrogen is separated from the product. The gas phase of the separator comes out, which ensures the hydrogen content of the gas phase of the separator, which is more conducive to the recovery or utilization of hydrogen. The process of the invention is conducive to the economical recovery of hydrogen, and can utilize the existing process for hydrogen recovery, thereby reducing the hydrogen consumption cost of the enterprise; meanwhile, the demand of the device for public works hydrogen is reduced, and the hydrogen utilization efficiency of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of petrochemical hydrogenation processes, and relates to a process method for gas-liquid separation of hydrogenation reaction products, particularly a gas-liquid separation process for a high-pressure hydrogenation reaction device. [0002] technical background [0003] With the heavy and inferior quality of global crude oil, the deep refining and cleaning of petroleum products, and the refined development of the downstream chemical industry, the petroleum processing technology has changed from simple to complex, from thermal processing to catalytic processing, from single technology to A variety of technologies coexist, from extensive to "environmentally friendly", and a leap forward has been made. Among them, as the most important means to produce clean transportation fuels and environmentally friendly oil products, it is an effective way to convert residual oil and heavy and inferior crude oil into high va...
