ABSTRACT:
Wash water is used to remove impurities such as hydrogen sulfide, ammonia, and hydrogen cyanide from light hydrocarbons and gases derived from refinery fluid catalytic cracking operations. The present invention is a process of low pressure recirculation of wash water combined with low pressure removal of waste water which results in the efficient removal of the above impurities at significantly reduced wash water rates.
