Abstract
A nonpolluting process for neutralizing corrosive acid components in the overheads of petroleum distillation units is disclosed. In the process, ammonia is added to said units and carried overhead. The overhead is condensed to yield hydrocarbon phase and an ammonia-containing aqueous phase. The aqueous phase is stripped to yield an ammoniacal steam that is returned to the distillation units and a substantially ammonia-free bottoms.
