Corrosion prevention in the coal tar processing industry

2015-09-24View Original

Thread Content

Coal tar has a complex composition; what are the corrosive components in it, and how does the coal tar processing industry prevent corrosion? I would appreciate advice from experienced sea travelers

Prevent NH3CL from decomposing into HCL, which can cause corrosion. Approximately 220–250 ammonia salts are decomposed. It is best for the feed coal tar to have a water content of 0.5% (using a super centrifuge)
