Achieve entry conditions in hours, not days, with a single chemistry program to de-oil, degas, and neutralize sulfides and pyrophorics. ZymeFlow® formulas are fully biodegradable and wastewater-friendly, fit cleanly into steam-out procedures, and help lower hydrocarbon loading to simplify effluent handling.

Cleaner. Faster. Greener. Safer.

While traditional steam-outs stack-on hardware, extra injection points, and follow-on steps, ZymeFlow’s patented, water-based chemistries are applied via Vapour-Phase®, our trademarked method that puts chemistry in the steam often with one injection point.. The result? True single-step decon: de-oil, clear LEL/benzene, and neutralize H₂S/pyrophorics with fewer hookups and less waste. 

  • Shorter timelines: Entry conditions in hours (often 8–12), not days.
  • Eco-forward chemistry: Biodegradable and wastewater-friendly.
  • Material-agnostic: Compatible with common alloys, gaskets, and seals.
  • Operator-friendly: Low-corrosivity, non-caustic at use strength formula

Meet the Family

A solution for every scenario — each product below addresses specific decontamination challenges while preserving a consistent, safety-first workflow.

ZymeFlow UN657: The Original

Our flagship water-based chemistry for rapid, plant-wide decontamination. UN657 integrates with Vapour-Phase or circulation to de-oil, clear LEL/benzene, and neutralize pyrophorics with a self-breaking emulsion that streamlines recovery.

  • Neutral pH at application strength for material friendliness

Have questions? We have answers.

How does Vapour-Phase® application work and why is it faster?

Vapour-Phase® puts the chemistry into steam for single-point coverage, reaching complex internals without extra injection points or added hardware. That reduces hookups, effluent, and turnaround time compared to traditional steam-outs. Typical completions: ~8–12 hours.

Which ZymeFlow chemistry is the default “broad-spectrum” option?

 ZymeFlow UN657 is the flagship. It’s a surfactant/oxidizer blend for Vapour-Phase® or circulation that de-oils, clears LEL/benzene, and neutralizes pyrophorics, often in 8–12 hours, with a self-breaking emulsion to streamline recovery.

What if ammonia is the primary concern?

Use Zyme-HT (“the Ammonia Breaker”) for Vapour-Phase® decontamination where trapped ammonia is present. It chemically neutralizes ammonia (not just masking it), while also handling sulfides, pyrophorics, and residual hydrocarbons — typically in 8–12 hours.

What if we can’t use much heat or need a circulation program?

Choose Zyme-Ox Plus. It’s a hybrid surfactant/oxidizer formulated for circulation and low-temperature conditions (effective below ~200 °F). It oxidizes pyrophoric iron sulfide, neutralizes ammonia, and can be used in presoaks/flushes for units that harbor pyrophorics.

Do these chemistries reduce wastewater and hydrocarbon loading?

 Yes. ZymeFlow programs are biodegradable and designed to minimize hydrocarbon loading. UN657’s self-breaking emulsion and rinse-clean profile help simplify effluent handling versus petroleum/terpene solvents.

Are ZymeFlow products compatible with common metallurgy and elastomers?

At use strength, ZymeFlow solutions are low-corrosivity/near-neutral pH and are compatible with common alloys, gaskets, and seals, supporting operator-friendly application.

What’s the offshore option, and is it environmentally compliant?

ZymeFlow OS is engineered for offshore platforms and FPSOs. It brings Vapour-Phase® efficiency with portable steam and carries REACH and CEFAS approvals (including a top “Gold”/lowest-hazard CHARM profile), making it suitable for sensitive marine environments.
