Analysis of the high consumption in dimethyl ether production
Thread Content
This post was last edited by *aojiaoya0546 on 2015-11-23 21:53. Recently, there has been high consumption of dimethyl ether and methanol; the operation conditions are normal, no leaks were found in the equipment, and the water at the bottom of the vaporization tower is of acceptable quality. I hope fellow users can help analyze what other possible causes might exist
Check the purity of methanol. . . . . . . . . . . . . .
A high one-way conversion rate should have a greater impact on steam consumption and electricity use, as there is no outward release of gas; analysis of the water at the bottom of the vaporization tower shows no methanol, and the reason for the high alcohol consumption remains unclear
The purity of methanol has decreased, but the consumption remains high
Is the carbon monoxide level in the exhaust gases high?
If the methanol level at the bottom of the vaporization tower is not high and there is no vent gas, then the problem lies not in the equipment. Check the methanol storage area; pay special attention to why the purity of the methanol is decreasing Are there any abnormalities in the water content at the bottom of the dimethyl ether tower? How is it compared to before?
Could you explain what the relationship is between the composition of the water at the bottom of the dimethyl ether tower and its consumption? The water from the bottom of this tower is sent directly to the vaporization tower
It’s not a water issue; check the returned methanol and the product
