ZymeFlow

What ZymeFlow does

ZymeFlow is a privately held chemical decontamination specialist founded in 1989 and headquartered in Houston, Texas. The company develops and applies proprietary water-based and solvent-based chemistries to remove hazardous contaminants—including hydrocarbons, pyrophoric iron sulfide, H2S, benzene, and VOCs—from refining, petrochemical, and LNG process equipment during turnarounds, maintenance, online operations, and pre-commissioning. Its product portfolio spans branded families such as ZymeFlow UN657 (water-based, VOC-compliant, biodegradable), Rezyd-X and Rezyd-HP (solvent-based heavy-oil dissolvers), CatZyme RT/LT/LTC (reactor decontamination chemistries for catalyst offloading), UltraZyme BT/FP (ultrasonic cleaning), the TankZyme family (3PS, H2S, SC, HP for tank cleaning), and the BAN Clean (Base/Acid/Neutralization) reactive chemistry approach launched in March 2025. These chemistries are deployed through the patented Vapour-Phase process, which delivers chemistry as hot vapor to reach areas that traditional liquid washes cannot.

Revenue is generated primarily through project-based decontamination service contracts at customer facilities, with proprietary chemistry sales accompanying engagements under non-public, quote-based pricing. ZymeFlow operates a global direct enterprise sales model with regional Directors of Business Development covering the US, Canada, APAC/India, Japan, Northern Europe, and Southern Europe, supported by a VP of Corporate Accounts & Sales and a channel partnership with Contract Resources for Australia, New Zealand, and Papua New Guinea. The company claims 75% of the world's 20 largest refineries as customers and executes over 200 turnaround projects annually across 55+ countries. Since December 2023 it has operated as a sister company to CR3 (an energy engineering solutions provider with 6,000+ staff) under common ownership, enabling a combined chemistry-plus-services platform spanning catalyst handling, industrial cleaning, mechanical maintenance, and shutdown/turnaround execution.

Certifications include ISO 45001 (occupational health and safety), REACH, and CEFAS; the company reports zero recordable incidents in its history. It recently opened a Canadian office in Edmonton (May 2025), launched Reactive Chemistry Solutions including HF and sulfuric alkylation capability (March 2025), and relocated its headquarters to a larger Houston facility with expanded labs (March 2026).
