fqe-degreaser-acmo-30

Alkaline degreaser for heavy oils/greases, compatible with stainless steel, rapid oil separation, caustic.

A large petrochemical company in Texas used FQE™ LEL-V and FQE™ Degreaser ACMO products to decontaminate and clean the quench oil, quench water, and caustic wash simultaneously.

 

All of the associated heat exchangers and piping were included in the cleaning path. Typically, it took several days to evacuate the system of hazardous vapors such as benzene. After 24 hours of steam phase injection, using FQE product, the towers were at zero LEL and zero benzene. The quench towers were circulated for 8 hours with FQE™ Degreaser ACMO to remove heavy oils. In prior cleaning trials, this method of cleaning required several days from shut down to return to maintenance

 

The plant estimated that over $300,000 was saved per tower compared to conventional cleaning methods.
