Reasons for high methanol sulfur content in low-temperature methanol washing and treatment methods
Thread Content
The sulfur content in the lean methanol stream from low-temperature methanol washing is always high. The design temperature at the bottom of the thermal regeneration tower is 88°C; when this temperature is increased to 90°C, dual operation of the reflux pumps is employed, yet the three-stage liquid level issue still cannot be resolved. Are there any effective solutions? (Please avoid analyzing both the reduction of temperature to lower sulfur content in the lean methanol stream and the handling of the three-stage liquid level issue resulting from increasing the temperature.) Thank you to all experts
It would be best to include a flowchart for easier analysis and discussion by everyone
