Abstract

Abstract An improved cylinder-shaped vertical type gas-liquid separator is disclosed. An inflow nozzle having a particular shape is mounted to a cylindrical body along its tangential direction. the cross-section area of the inflow nozzle is not decreased from its inlet along the inflow direction of a gas-liquid two-phase flow. The bottom surface of the inflow nozzle is inclined so as to be lowered along the flow direction at an inclination angle in the range of 30 degrees or less. The width of the inflow nozzle is held equal or gradually narrowed along the flow direction of the two-phase flow. The width at the spouting end of the inflow nozzle is narrower than the width of an annular circling flow path formed between the cylindrical body and a gas discharge pipe provided at the central portion of the cylindrical body. Preferably, in inflow nozzle is extended into the cylindrical body. More preferably, the inclination angle of the bottom surface of the inflow nozzle is chosen at 10° - 15°. Also, more preferably, the length of the inclined portion of the bottom surface of the inflow nozzle is chosen to be equal to about three times or more of an inlet pipe diameter.
