Benzene and hydrogen sulfide free
Zero LEL’s after 12 hours of vapor phase steam injection
No iron sulfide combustion
The equipment was decontaminated with iron sulfide scale, LEL content gases and hydrogen sulfide from the process. Decontamination was required for scheduled maintenance work. The equipment was cleaned by vapor phase steam injection with FQE H2S and FQE LEL-V for degassing of hazardous vapors. It was then treated with FQE Pyrophoric to deactivate the iron sulfide scale.
After 12 hours of chemical injection, the equipment was successfully degassed with no benzene, hydrocarbon or hydrogen sulfide present on analysis. On opening the vessel, the equipment was clean and no iron sulfide scale combustion was encountered. The associated equipment was cleaned by liquid circulation as needed. The wash water was sent directly to waste water treatment without delay.
Previous work conducted by competitors had left noticeable hydrocarbon odors and there was none following FQE LEL-V application.
