Why does a liquefied gas desulfurization system produce gum?
Thread Content
In the liquefied gas desulfurization system, a large amount of viscous black substance, similar to \"asphalt,\" is generated in the lean liquid cooler after the rich liquid is regenerated, and this substance is difficult to remove. What is the cause of the production of this substance? ? ?
In the liquefied gas desulfurization system, a large amount of viscous black substance similar to \"asphalt\" that is difficult to remove forms in the lean liquid cooler after the rich liquid has been regenerated. The main reasons for this are excessive temperatures at the top of the regeneration tower or at the heat source at the bottom of the tower, as well as the degradation of the amine solution. Adjusting the operating conditions will reduce it.
Reply to 2# zhsju0315: I really don’t know about this. Thanks for the reminder. My operations have not been very stable lately; the temperature of the gas returning sometimes exceeds 125 degrees. I assume everyone should keep this temperature at the same level, right? Another point is whether to control the temperature at the bottom of the tower or the temperature of the returning gas I’ve heard that heating media often consist of steam that has been cooled and depressurized. Is it possible to use steam at 0.8 MPa and 180 degrees?
Our bottom temperature has always been 100 degrees, and there is also gum at the bottom of the reboiler
