In the refining and petrochemical world, time is critical, and safety is non-negotiable. Unexpected contamination can bring operations to a halt, resulting in millions of dollars in lost production. That’s why modern decontamination strategies must go beyond traditional cleaning. With BAN Clean—ZymeFlow’s proprietary Base, Acid, Neutralization cleaning approach, plants are achieving faster turnarounds, deeper cleans, and improved safety, all while reducing environmental impact.
For over 35 years, ZymeFlow has been the global leader in chemical cleaning and decontamination, using reactive chemistry to tackle the industry’s most complex challenges. BAN Clean is a prime example of how reactive cleaning delivers results that conventional methods simply can't match.
BAN Clean stands for Base, Acid, Neutralization—a strategic, stepwise application of specially engineered chemistries designed to dissolve, neutralize, and remove tough contaminants. Each phase of BAN Clean targets a different class of foulant, ensuring complete system decontamination:
This reactive cleaning sequence operates at the molecular level, converting hazardous compounds into safer byproducts more quickly and efficiently than flushing or steaming alone.
In industrial units, contaminants such as pyrophoric iron sulfide, hydrocarbon residues, hydrogen sulfide, and volatile organic compounds (VOCs) pose serious safety hazards. BAN Clean reactive formulations are engineered to:
By working proactively and chemically, BAN Clean significantly reduces gas-freeing time and enhances overall safety outcomes.
ZymeFlow’s BAN Clean process is more than a set of chemicals—it’s a comprehensive, field-proven cleaning strategy. Here’s how it delivers exceptional value across refinery and petrochemical turnarounds:
Each step, Base, Acid, and Neutralization, is engineered to address different contaminants in a single continuous process, reducing downtime and eliminating the need for separate treatments.
Reactive formulations rapidly break down VOCs, H₂S, and combustible gases, often cutting turnaround prep time by 30–50% compared to conventional steam-outs or solvent washes.
BAN Clean can begin while the unit is still online, removing buildup and preparing equipment in advance. This minimizes manual cleaning after shutdown and allows for quicker mechanical entry once the system is offline.
Compared to traditional flushing, BAN Clean uses less water and generates minimal waste streams, lowering environmental impact and disposal costs.
With fewer confined space entries and lower exposure to toxics, BAN Clean helps operators meet stringent OSHA, EPA, and internal HSE standards.
From Crude Distillation, Vacuum, Hydrotreaters, Reactors, Gas Plants, Sour Water Plants, FCC Units, Coker Units, Quench Towers to Sulfuric and Hydrofluoric Alkylation Units. ZymeFlow’s BAN Clean approach has been applied to some of the most challenging refinery systems worldwide.
Our teams collaborate directly with site engineers and turnaround planners to customize every cleaning project, adapting chemistry, flow paths, and application timelines to suit each plant’s specific configuration and constraints.
At ZymeFlow, we believe reactive cleaning is more than a chemical solution; it’s an operational advantage. With the BAN Clean system, you get:
Whether you’re planning your next major turnaround or preparing for an emergency cleanout, ZymeFlow’s BAN Clean gives you control, confidence, and cleaner results faster.
