What's the matter with the redness caused by benzene acid washing color comparison?
Thread Content
Our benzene has failed to pass the pickling color test for more than a month in a row, and the benzene after acid washing turned red after whitening. We initially suspected that it was caused by the reforming catalyst reaching the end of the stage. May I ask what is the reason for the red color in the benzene pickling color test? Thanks!
