Engineering support that turns energy waste into verified savings

We work with process plants, refineries, and industrial asset owners across the full arc of an efficiency project — from the first steam audit through commissioning, verification, and the training that keeps the savings in place.

01

Assess & optimize

Find where energy and money are actually leaving the plant, then engineer the fix.

  • Audits & modeling — steam, condensate, and energy audits backed by full system balance models.
  • Optimization & solutions — targeted measures to cut energy and utility cost and eliminate LP steam venting.
  • Specialized system support — boilers, high-temperature furnaces, kilns, asphalt systems, and refinery fuel usage.
  • Troubleshooting & safety — resolution of complex faults, including water hammer in process plant steam systems.
02

Engineer & specify

Turn the recommendation into a design package that contractors can bid and build against.

  • BDS development — comprehensive Basic Design Specification packages for technical proposals.
  • Design peer review — critical review and refinement of engineering scopes drafted by third parties.
  • Package reviews — detailed design and bidding packages checked for alignment and quality.
  • Implementation guidance — engineering oversight and support through project execution.
03

Verify & sustain

Prove the savings landed, then build the habits and instrumentation that hold them.

  • Commissioning support — pre-commissioning reviews, system testing, and full commissioning.
  • Performance validation — stabilized operation to establish and verify the savings achieved.
  • Monitoring programs — durable measurement and monitoring frameworks for energy efficiency.
  • Training & culture — energy-cost awareness across personnel, with client engineers involved directly in the work.

Case studies

Proven savings across industrial steam and process systems

From plant-wide energy assessments to single-line heat integration, we find the losses hiding in equipment you already own — and turn them into measurable annual savings.

Steam system assessment Ammonia & fertilizer

497,000 GJ cut from an ammonia plant's steam system

A US DOE Save Energy Now assessment at the Verdigris, Oklahoma plant led to upgraded condensing turbines, a new loop dehydrator, and a steam trap and leak repair program.

Result
$3.5M saved a year
Outcome
11-month payback
Drive optimization Petroleum refining

A no-capital load strategy for a UK refinery's steam balance

Costing every turbine drive against its electric motor alternative showed which units to switch as low-pressure steam went to vent — cutting the ethane compressor from $84.84/hr to $12.60/hr when exhaust steam is fully used.

Result
$30k saved a year
Outcome
Zero capital spend
Turbine performance Commodity chemicals

500 kW recovered by retiring an obsolete desuperheater

After a waste-heat boiler was tied in, combined steam to the extraction-condensing turbine stayed below its 660°F inlet limit — so desuperheating could be safely bypassed and the lost work returned to the generator.

Result
$400k saved a year
Outcome
Piping change only
Heat integration Chemical plant utilities

A cooling tower replacement avoided by rerouting makeup water

Boiler makeup water at 115–150 gpm almost exactly matched the air compressor's 120 gpm cooling duty, so it was routed through the compressor to preheat feedwater and the failing tower was blinded off.

Result
$80k saved a year
Outcome
Live in two months
