The carbonylation synthesis devices comprise a methanol synthesis device, an ethanol synthesis device, an ethylene glycol synthesis device, a methyl formate synthesis device and the like, and a rectifying tower is generally adopted to remove dissolved gas and non-condensable gas in liquid products during synthesis. The product is treated by adopting the noncondensable gas separation device of the methanol rectifying tower during the carbonylation synthesis of the methanol, and due to the reasons of large working condition fluctuation, large noncondensable gas release amount, high carbon dioxide concentration, high liquid material carrying capacity and the like of the methanol synthesis device, the material needs to be fully captured and recovered to avoid the material running loss and consumption exceeding the standard, and the noncondensable gas of the rectifying tower needs to be deeply purified.

At present, many enterprises at home and abroad, especially enterprises in the coal chemical industry, mostly adopt a traditional simple non-condensable gas separation device in the non-condensable gas separation process of a rectifying tower during the synthesis of methanol and ethylene glycol. The main disadvantages of the non-condensable gas separation devices of the rectifying towers are that: 1) the separator has poor adaptability to variable fluctuation conditions. 2) The gas-liquid separation efficiency of the separation device is low, the material loss is large, and the material consumption exceeds the standard seriously. 3) The noncondensable gas discharged by the separation device has high liquid carrying capacity, the liquid accumulation of a subsequent pipeline is obvious, the noncondensable gas is not smoothly discharged, and the potential safety hazards of liquid hammer and liquid impact operation exist in time.
