Abstract

The invention discloses a micro-cyclone reinforced separation device and a micro-cyclone reinforced separation method for a cold-high-pressure separator. The micro-cyclone reinforced separation device for the cold-high-pressure separator in a hydrogenation reaction process comprises a cylindrical pressure vessel (1) and a micro-cyclone tube bank (2), wherein the micro-cyclone tube bank consists of one or more micro-cyclone tubes. The device has a simple structure and high separation accuracy; in the high-pressure separator of the hydrogenation reaction process, a high-pressure multi-phase mixture containing liquid particles and gas is subjected to reinforcement of micro-cyclone separation; effective micro-cyclone separation of the liquid particles and the gas in the high-pressure multi-phase mixture is finished under an extremely low pressure; the separation accuracy of the cold-high-pressure separator is improved; the manufacturing cost of the cold-high-pressure separator is reduced; and the device and the method are particularly suitable for operation conditions of high pressure and ultrahigh pressure.

Description

technical field [0001] The invention belongs to the technical field of petroleum processing, and relates to a micro-swirl flow enhanced separation device and method for a multi-phase mixture entraining liquid droplets or particles in a high-pressure gas, more specifically, to a cold high-pressure separation in a hydrogenation reaction process A micro-cyclone enhanced separation device and method for a device. Background technique [0002] In the petroleum refining industry, the separation process of hydrocracking reaction products usually has a cold high fraction process and a hot high fraction process. Generally, the flow of gas-liquid separation after all the reaction products pass through the cold high-pressure separator is called the cold high fraction flow. The cold high-pressure separator completes the gas-liquid separation of the hydrogenation reaction effluent, the separated gas phase is returned to the reactor as circulating hydrogen, and the separated liquid phase...
