Enhanced distillation for the world’s refineries.
DWC Innovations delivers dividing-wall columns and process intensification that debottleneck units, cut energy and boost yield — reducing CAPEX and OPEX by 20–50% across refineries and petrochemical complexes.
We reinvented the Dividing Wall Column — and made it work at scale.
DWC Innovations is a recognized global leader in Dividing Wall Column technology — licensing, process design and engineering for refiners and petrochemical producers worldwide, from our headquarters in Houston, Texas.
We specialize in revamps that remove bottlenecks and expand capacity inside the columns you already own.
Our innovations across the value chain
From dividing-wall column licensing to process optimization and full engineering delivery — helping refineries do more with the assets they already have.
DWC Prime & Dual DWC Prime
Single- and multi-wall dividing wall columns — including TDWC and BDWC Prime — that replace two-column sequences, sidecut columns and indirect trains.
Octane Booster
Boost octane and throughput of light-naphtha (C5–C6) isomerization units without new columns — DWC Prime retrofits into the existing deisohexanizer.
Food Grade Hexane
Revamp the deisohexanizer to produce a valuable 4th cut — food-grade, polymer-grade or isohexane — raising isom-unit capacity by 20%+.
Benzene Saturation
Ben Prime technology manages benzene in the gasoline pool with a cost-effective saturation solution that meets stringent regulatory requirements.
CS₂ Removal
DWC Prime reduces carbon disulfide (CS₂) contamination in petrochemical naphtha to below 2 ppm — protecting downstream catalysts and equipment.
Refinery Process Optimization
Capacity increase, margin improvement and energy reduction — heat-pump and multi-effect distillation that save 20–50% in CAPEX and OPEX.
Results on real units
- Single column, multi-cut separationThree or more high-purity product streams from a single shell.
- Major capacity upliftRevamp side-cut columns without adding new equipment.
- Sharper separations, higher valueUpgrade low-value streams into premium products.
- 50% lower footprint & energyFewer columns, less plot space, minimal external changes.
- 20–50% lower CAPEX & OPEXFast payback with proven commercial performance.
- Debottlenecks downstream unitsSupports Isomerization, CCR, PX and Aromatics Recovery.
What does the energy saving weigh in carbon?
Put in the reboiler duties you run today. See the CO₂e a dividing wall avoids each year, what that saving is worth, and how it measures against a whole refinery.

Reboiler duty, two columns → one
The wall removes the remixing between the two columns — that recovered 19.2 MMkcal/h is 92,494 t CO₂e a year.
