Elimination of leakage points in the methanol distillation air cooler
Thread Content
Hello, everyone who is into the sea. Our distillation air coolers have been in use for about 10 years, and now there is methanol leaking from the tubes of these coolers. To ensure continuous production, we have to use methods such as placing something between the straps to stop the leaks and supplementing nitrogen to control the temperature difference. Are there any other good solutions? Could you please provide some guidance?
You are referring to the atmospheric pressure tower, right? I wonder what the temperature of the methanol at the outlet is controlled to be? The start and stop of the air cooler fan should be planned based on the outlet temperature
Yes, the outlet temperature of the air cooler is generally around 60°C
Chief Qian, increase the export pressure to reduce flashing and prevent gas-liquid mixing from scouring the tubes. {:9015:}
Thank you, Teacher Qin, for your guidance; I hope you can teach me more
The erosion of heat exchange equipment by methanol vapor-liquid mixtures is difficult to avoid; it is recommended to control the load or plug individual tubes to prevent leaks
Does the methanol distillation system have air coolers? Could you send a screenshot of the control panel?
