Abstract

The invention discloses a high-pressure separator and a method for high-pressure separation, and is characterized in that: a cyclone gas-liquid separator is disposed on the middle-upper part of a housing of the high-pressure separator; the cyclone gas-liquid separator is connected to the housing of the high-pressure separator through a column tray plate or a gas-collecting pipe; mixed gas entering the high-pressure separator is cyclone-separated by the cyclone gas-liquid separator; after oil, water and few solid particles are removed, the gas is discharged from the high-pressure separator. The invention can reduce the gas phase molecular weight of the high-pressure separator, eliminate physical factors which cause foaming of desulfurizers in a desulfurization tower, and prolong the continuous operation period of the whole device.

Description

technical field [0001] The invention belongs to the field of physical separation, and relates to a method of using a gas-liquid cyclone separator to treat oil, water and fine solids carried by hydrogen in a high-pressure separator (including a hot high-pressure separator and a cold high-pressure separator) in a hydrocracking process A high-pressure separator for particles and other substances and a method for high-pressure separation. Background technique [0002] The hydrogenation unit is equipped with a high-pressure separator (high fraction), which separates the three phases of oil-gas-water in the effluent of the reactor, and serves as a buffer when the operating volume is unstable and the gas contains a large amount of liquid. For this reason, suitable gas phase separation space and sufficient liquid phase residence time are required. The wall thickness of the high-pressure separator varies with the operating pressure and the diameter. Some wall thicknesses are less t...
