Advanced Separation Technology, Proven in Operating Plants
Dividing wall column technology, process optimization and engineering — delivered by one team.
Who we are
We Commercialize What Others Only Model
Advanced Distillation & Separation Specialists
We reintroduced the dividing wall column to commercial service. Today we apply that expertise across distillation, separations and refinery process units.
Houston-Based. Operating Globally.
Supporting refinery, petrochemical and chemical clients across North America, the Middle East and Asia from our Houston headquarters.
Proprietary technology
Licensed dividing wall column technology and internals — the flagship, and the reason most clients find us.
Process optimization & solutions
Debottlenecking, energy and margin optimization, and proven application packages — with or without a dividing wall.
Engineering & execution
Feasibility study to start-up, including column and internals supply.
Track record
A Record of Industry Firsts
World’s First Commercial Dual DWC
A Dual DWC DAS splitter at BPCL Mumbai, built as part of a lube base oil unit revamp.
Read press release →Turnkey Dual DWC Revamp at MRPL
A naphtha splitter converted to a Dual DWC with no change in reboiler duty. Performance test passed in April 2026.
Read press release →Food- and Pharma-Grade Hexane at CPCL
A Dual DWC deisohexanizer producing both food- and pharma-grade hexane from an existing isomerization unit.
Read press release →CS₂ Below 1 ppm in Petrochemical Naphtha
A DWC Prime column met a new CS₂ regulation without a hydrotreater revamp.

What Clients Get
More Capacity
Debottleneck existing columns without adding a new tower.
Lower Energy and Capex
One shell does the work of two or three conventional columns.
Higher-Value Products
Extra on-spec cuts from the same feed.
Specifications Met
Tighter purity and regulatory specs met with minimal new equipment.
Practical Economics
Every recommendation is backed by payback and project economics.
Industries we serve
Our purpose
To help refiners and chemical producers get more from every column, existing or new, through advanced separation technology.
