Engineered Planning

Our industry-experienced decontamination planners embed with your refinery personnel to ensure tasks are managed and consistent with your design limits and specifications, while maximizing uptime and a quick return to business operations. We use state of the art software to provide customized and easy to understand procedures, drawings and timelines to ensure the decontamination portion of the shutdown is carried out as smoothly and efficiently as possible.

Reactor Cleaning

We've revolutionized reactor cleaning with CatZyme - our proprietary solvent-based chemistry. This effective chemistry boosts removal of residual gases, helps dissolve any existing solid deposits, and acts as a scrubber to collect LEL. Simply put, if you're looking for a more efficient and fast reactor cleaning, then you need ZymeFlow's reactor cleaning services.

Online Cleaning

Sometimes your equipment can't wait for the scheduled turnaround but you need to keep producing revenue. Customers worldwide turn to us to develop a custom online cleaning plan to keep the unit running  until the scheduled outage. Whether it's segmenting heat exchangers or performing true online cleaning, our team utilizes innovative chemistry and processes to keep you running.

The Best Chemistry Meets The Right Application

Give us your challenge. We'll give you the custom solution. We utilize application methods and chemistries in a singular or multi-phase approach to achieve maximum results - and we do this more than 200 times a year for our customers around the world.

We have the best chemistry in the industry. PERIOD. 

Applications
  • Vapour-Phase
  • Boil Out
  • Circulation
  • Combination Treatments
  • Pre-Post Treatments
  • Dry gas Dispersions

Incomparable Chemistry

ZymeFlow set the standard in chemical decontamination with its development of the flagship chemistry ZymeFlow. Since then, an entire suite of proprietary water- and solvent-based formulations have been created and utilized. We are trusted innovators that continue to develop products for the industry's toughest cleaning challenges.  Our entire family of ZymeFlow chemistries are complementary and can be used together safely and effectively. Furthermore, the ZymeFlow family of chemistries are fully compatible with all metallurgy and seal/gasket material.

 
Water Based
  • Fast-acting and wastewater friendly
  • Simultaneous contaminant treatment - de-oils while eliminating LEL, benzene, H2S, and pyrophorics
  • Can be applied in many different methods including a true Vapour-Phase using steam
Solvent Based
  • Dissolves binders to clean heavily fouled equipment
  • Easily reprocessed in the refinery without negative impact on product stream

A Return Engagement

After successfully completing an initial decontamination project for a South Louisiana refinery, ZymeFlow was invited to return for a large turnaround project. The unit needed to be ready for entry in a short timeframe and ZymeFlow delivered.

We’ve Got Decontamination Planning Down To A Formula

Site Visit and Kickoff

Once you select ZymeFlow - the process begins. Most engagements start with a site visit to review your turnaround goals with your team. Once we have the lay of the land, we move onto the development of the plan.

Site Visit Steps Include:
  • Kickoff and scope overview
  • Walk down associated equipment
  • Development of decon path and procedures
  • Identify injection, drains and vents

Plan Development

This phase involves detailed planning and scheduling. We'll draft and submit preliminary drawings and guidelines for client approval. As true collaborators in the process, we welcome your input, direction and revisions as the planning manual is developed. 

Planning Manual includes:
  • Drawings broken down by circuit
  • Chemical decontamination procedures
  • Chemical injection tag list
  • Detail mechanical listing
  • The safety matrix
  • SDS's

Planning Finalization

Upon approval of the planning manual our team will assist with operational training, MOC review or plan review as requested by the facility. At the appropriate time, our planners will affix injection and drain tags in the appropriate locations. 

Finalization Includes:
  • Operator training
  • Injection and drain tagging
  • Execution kickoff

CTA Module

CatZyme RT™ guarantees repeatable results for reactor cleaning, by being predictable and plannable, so efficiencies are achieved and timelines are met. Cleaning time is optimized, with minimal personnel and reduced shifts required, so you can get back to business as soon as possible.

Video Section - Reform And Transform

Traditionally, reactor cleaning has been performed in a variety of ways – all of which are dated. Hydrogen sweep/nitrogen purge is incapable of completely removing LEL & hydrogen sulfide, or addressing heavy end deposits remaining on the catalyst, and perhaps most importantly, there is a safety risk to personnel. Our CatZyme RT™ process will eliminate all concerns.

We are called innovators for a reason.  As one of the only companies on the globe equipped and experienced enough to tackle this process, ZymeFlow offers improved, predictable, plannable solutions.
