Having worked in over 50 countries and for most of the major oil and gas companies around the world, ZymeFlow has an impressive customer reference list.

Refinery and Petrochemical Vessel Decontamination


ZymeFlow Decon has planned and applied chemistry to almost every process system in a refinery including: desalter, atmospheric distillation, vacuum distillation, hydrotreater, catalytic reformer, distillate hydrotreater, fluid catalytic cracker (FCC), hydrocracker, visbreaker, merox, coker (delayed coker, fluid coker, flexicoker), alkylation, dimerization, isomerization, reformer, horizontal vessel, amine, and sour water stripper.


Additionally, the team boasts a wide range of petrochemical experience preparing units for entry in the following areas: ethylene, propylene, butadiene, and aromatics. From single units to full plant turnarounds, ZymeFlow has the experience and personnel to provide fast and safe results. After the decontamination is complete, customers are able to confidently enter process vessels for inspections and maintenance including hot work without the need for fresh air equipment.


Specialty Markets


As an extension to the main refinery and petrochemical decontamination business, ZymeFlow Decon also serves a select group of specialty markets including: decontamination for plant decommissioning, offshore unit decontamination, and pulp and paper process unit decontamination. In each of these markets, ZymeFlow delivers the same goals of faster, safer, vessel entry.
