Problems solved by technology

But there is a problem: Although the secondary separation improves the gas-liquid separation effect, the liquid separated by the secondary separation and the acid slag produced by oversulfonation are deposited at the bottom of the cyclone separator or the separator, which is easy to block the lower outlet. , after clogging, it needs to be cleaned manually, and the waste time and power are used to clean up, and the cleaned materials are all treated as waste, resulting in material loss and environmental pollution

Abstract

The invention discloses a gas-liquid separation device, which comprises a film sulfonation reactor, a gas-liquid separator and a separator. An inlet of the film sulfonation reactor is connected to a feed pipeline. The gas-liquid separator contains a first inlet and a second inlet, wherein the first inlet is communicated with an outlet of the sulfonation reactor. An inlet of a settling separator is communicated with an outlet of the gas-liquid separator through a first pipe section group, and an outlet of the settling separator is communicated with the second inlet. The settling separator receives tail gas obtained after primary separation by the gas-liquid separator and carries out secondary gas-liquid separation on the tail gas. The gas-liquid separator receives a separation liquid obtained after the secondary gas-liquid separation. The invention also discloses a separation liquid recovery method by using the above gas-liquid separation device.

Description

technical field [0001] The invention relates to a gas-liquid separation device, in particular to a gas-liquid separation device and a separation liquid recovery method for avoiding equipment and pipeline blockage, coking and corrosion, and realizing separation liquid recovery and reuse. Background technique [0002] Sulfonation reaction is an important reaction type for the synthesis of various organic chemicals, and plays an extremely important role in the synthesis of fine chemicals. Using gas-phase sulfur trioxide as sulfonating agent, alkylbenzene, alcohol ether, fatty alcohol, α-olefin, heavy alkylbenzene, petroleum distillate, etc. In the field of surfactants in the industrial and daily chemical industry, the core equipment of the sulfonation reaction is the sulfonation reactor. After the sulfonation reaction is completed, the gas-liquid separator is generally used for gas-liquid separation, but there are still some substances after the gas-liquid separation. Foam ent...
