Sum-Up of Technical Transformation of 1 800 kt/a Methanol Synthesis Unit
YI Hongmin;Shenhua Xinjiang Chemical Co., Ltd.;
Some problems occurred in actual operation of the 1 800 kt/a methanol synthesis unit, such as the low gas pressure difference of the first seal gas of the syngas compressor dry gas seals, the wax precipitation of the MTO grade methanol condenser and the crude methanol water condenser, high return water temperature of circulating water of extractor of the syngas compressor, etc., and these problems affect the stable operation of the unit. In connection with existing problems, corresponding technical transformation measures are taken, and the long-term, full-load, safe and stable operation of the methanol synthesis unit is ensured.
