Major B&W Scope at This Complex
The Challenge: Cleaning Specifications With No Margin for Interpretation
Ethane cracking furnaces are among the most demanding systems to pre-commission in the petrochemical industry. They operate at extreme temperatures, process highly reactive feedstocks and feed directly into downstream units where contamination can easily spread.
To add to the stakes, these were among some of the largest furnaces of this design in the industry, and the equipment manufacturer’s cleaning specifications were among the most stringent B&W’s engineers had encountered.
B&W had already completed a major pre-commissioning scope at this same complex: chemical cleaning and high-velocity oil flushing for two polyethylene production units. The B&W team was grateful to be selected for the ethane cracker unit based on that performance.
Key Pre-Commissioning Challenges
- Manufacturer cleaning specifications required strict compliance, and any deviation risked voiding equipment warranties and delaying startup
- Seven furnaces required coordinated cleaning sequences with precise timing to avoid cross-contamination between units
- Raw water on-site required treatment to produce demineralized water of the right purity for both cleaning circuits and hydrotesting
- Waste effluent generated by the program couldn’t be discharged on-site, so the job required full containment and coordinated off-site disposal
- The program’s scale demanded simultaneous engineering oversight and field execution without compromising either
B&W’s Role: End-to-End Engineering and Field Execution
The scope for the ethane cracker unit was unusually comprehensive. B&W’s in-house engineering team:
- Developed the cleaning specifications
- Managed water treatment in the field
- Took ownership of waste effluent containment and disposal alongside the core chemical cleaning execution
Why This Project Required B&W
The client needed more than a cleaning contractor. They needed a partner who could:
- Engineer a custom cleaning program to meet the equipment manufacturer’s exact specifications
- Produce and store demineralized water on-site from the raw water supply with no reliance on third-party supply chains
- Contain and manage all waste effluent through to compliant offsite disposal
- Coordinate simultaneous cleaning of seven furnaces without cross-contamination risk
- Bring an established relationship and proven performance from the prior scope at the same complex

Repeat client (second major scope at this complex)
“When a client brings you back for a harder scope at the same facility, the message is clear—they trusted what you delivered the first time and they’re raising the bar for the second. Our team treated this project the same way we treat every project: engineer it precisely, execute it safely and leave nothing to chance.”

Chemical Cleaning
B&W developed and executed a custom chemical cleaning program for all seven ethane cracking furnaces, specifically formulated to meet the equipment manufacturer’s stringent cleanliness requirements. Chemistry, concentration, temperature and contact time were engineered for this application, not adapted from a generic protocol.
On-Site Water Treatment
Chemical cleaning and hydrotesting at this scale requires large volumes of demineralized water—water of a purity that raw site supply can’t provide. Rather than relying on third-party supply, B&W engineered and operated an on-site water treatment capability, producing and storing demineralized water throughout the program.
Waste Effluent Containment & Disposal
Chemical cleaning generates waste effluent that can’t be discharged on-site. B&W took full ownership of that obligation, containing all waste generated by the cleaning program and coordinating compliant off-site disposal.
Pre-Commissioning Engineering
B&W’s engineering team was fully responsible for the cleaning program’s design, not just its field execution. That means the cleaning specifications, water treatment design, sequencing logic and waste management plan were all developed in-house, with a single engineering team accountable for how each element was connected.
Critical Infrastructure for the Region
At $8.5 billion, this project represented one of the most significant industrial investments in Southeast Texas in recent history. B&W’s pre-commissioning work on the ethane cracker unit was a necessary condition for the facility reaching commercial operation on schedule. The seven furnaces B&W cleaned are now the heart of the complex’s production.
A Complex Scope With A Single Accountable Partner
When your pre-commissioning program involves custom engineering, on-site water treatment, and full waste management—in addition to the cleaning itself—you need a contractor who can own it all. Talk to B&W about your next petrochemical project.
