This post was last edited by Xiao Gong 1985 on 2016-5-5 08:14. The reaction products have caused severe corrosion in the back section of the isobutane removal tower, rendering it unable to function. Are there any good material solutions for this issue?
You should discuss this suggestion with the manufacturer and have the internal design of the tower modified, selecting appropriate materials. Manufacturers usually have alternative solutions available; it’s best to tell them what reactants you will be using during the discussion, as otherwise it’s hard to predict the outcome.
Conduct chromatographic analysis to identify the various corrosive agents present, and select an appropriate material based on those agents
First, determine the cause of corrosion and the medium involved, then select the appropriate material
Haiyou, it seems that your facility is operating at full capacity, which results in the production of large amounts of acid esters. These substances break down into acidic compounds within the isobutane tower, causing corrosion to the components inside the tower. It is likely that the tubes of the air coolers and water coolers will also suffer from corrosion.
The pH value of the feed material to the isobutane distillation column has reached around 2
