Worldwide Leader in Decontamination

Faster, Safer, Vessel Entry.

Refinery Services and Chemistries

ZymeFlow® Decon Technology specializes exclusively in the decontamination of hydrocarbon process vessels. Decontamination can be completed in 8-12 hours with minimum effluent using the patented ZymeFlow Vapour-Phase® Process. A successful decontamination project will de-oil the equipment and result in zero hydrogen sulfide (H2S), zero benzene, zero combustible gases (LEL), and treated pyrophoric iron sulfides. The vessel will be ready for entry without the need for fresh air equipment so that inspection and maintenance, including hot work, can be performed. ZymeFlow decontamination is effective on almost every process unit in a refinery.


In addition to general decontamination, ZymeFlow Decon offers a range of supporting chemistries and services for unique or challenging applications. Additional services include cleaning heat exchangers to regain efficiency, fluidizing tower bottoms using oil wash enhancements, and packed coke conditioning for ease of removal.
