Solutions for the liquid seal formation caused by fluid accumulation in methanol synthesis elbows!

Thread Content

This plant features a methanol production system with an annual capacity of 100,000 tons; after exiting the reactor, the syngas is enriched in steam using a waste heat boiler, and then divided into two streams – one stream is sent to an exchanger for heat exchange, while the other stream is sent to a soft water heater to heat the soft water. The syngas pipeline has downward elbows at both the inlet and outlet of the soft water heater, with an elbow height of about two meters. Due to temperature regulation, the operator accidentally closed the valve that controls the gas flow to the soft water heater. Some of the condensed methanol accumulated at the elbow. The pressure difference in the soft water heater is low, so it cannot remove the condensed methanol. It has restricted production. I earnestly ask all experts to only recruit!
