Low-temperature separator for treating natural gas with large amount of light hydrocarbon-containing liquid

According to the low-temperature separator for treating the large amount of light hydrocarbon-containing liquid in natural gas, a shell is divided into a liquid phase space and a gas-liquid separation space, and the condition that the liquid phase space is larger than the gas-liquid separation space is met; the medium inlet is tangentially formed in the position, adjacent to the liquid phase space and the gas-liquid separation space, of the shell, an inlet diffuser is arranged at the medium inlet, a separation assembly is installed in the position, above the inlet diffuser, in the gas-liquid separation space, and the separation assembly is a three-stage separation assembly; a coalescence screen mesh, an NC-TP plate separation assembly and a guide vane type cyclone tube with a rotation stopping structure are concentrically and sequentially arranged from a fluid inlet in the center of the shell to the periphery. According to the multi-stage centrifugal separation device, the separation efficiency is greatly imp
