The reboiler temperature and bottom temperature of the isobutane stripping column fail to increase
Thread Content
After washing the alkylation deisobutane column, the temperature at the refeed point and at the bottom of the column fails to rise; it fluctuates constantly. Water removal at the bottom of the column as well as in the reflux tank does not work properly
You mean the isobutane removal tower after the materials are washed. Which return tower temperature are you referring to?
