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, bringing together a team of technocrats delivering state-of-the-art innovations, process technologies and engineering solutions to clients worldwide.
We specialize in advanced revamping solutions that enhance operational efficiency and eliminate process bottlenecks — helping petrochemical and process industries expand capacity and optimize performance. Headquartered in Houston, Texas, our reach now spans global markets.
Our Mission
Deliver innovative process solutions and comprehensive engineering services that help clients achieve greater efficiency, reliability and performance.
Our Vision
To be the world’s leading innovator in process intensification and separation technologies for cleaner, more efficient operations.
One technology, six ways it pays back
Single column, multi-cut separation
Three or more high-purity product streams from a single shell.
Major capacity uplift
Revamp side-cut columns without adding new equipment.
Sharper separations, higher value
Upgrade low-value streams into premium products.
50% lower footprint & energy
Fewer columns, less plot space, minimal external changes.
20–50% lower CAPEX & OPEX
Fast payback with proven commercial performance.
Debottlenecks downstream units
Supports Isomerization, CCR, PX and Aromatics Recovery.
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.
Multi-wall Dividing Wall Column at BPCL Mumbai
The world’s first commercial application of a Dividing Wall Column with multiple walls — engineered, licensed and commissioned by DWC Innovations.
A complete package, from feasibility to installation
We take projects from critical process evaluation through optimized design, procurement, fabrication and commissioning — backed by full-scope DWC Prime expertise.
Robust control schemes
Developed through extensive dynamic simulation and advanced control modeling.
Local manufacturing of internals
Shorter delivery schedules and stronger project economics.
Energy optimization
Integrated heat-load strategies for lower overall utility consumption.
Complete project management
Engineering, procurement, fabrication, installation and start-up end-to-end.
End-to-end engineering, feasibility to start-up
Complete process solutions delivered by Team DWC — concept studies through detailed design and on-site support.
Commercial milestones refiners can build on
We don’t just license technology — we take projects through successful commissioning at some of the most demanding refineries in the world.
World’s first multi-column DWC network commissioned
World’s first multi-column DWC Prime network commissioned in India, replacing seven conventional columns with four high-efficiency DWC units.
Pharma-grade hexane via Dual DWC deisohexanizer
Dual dividing-wall deisohexanizer producing pharma-grade hexane in the isomerization unit — with a 20% unit-capacity increase.
Turnkey dual DWC revamp for optimized naphtha separation
Turnkey revamp with dual DWC delivered sharper three-cut naphtha separation, stable control and unchanged reboiler duty.
Technical articles & journal features
Peer-reviewed thinking on distillation, dividing-wall technology and refinery optimization — published in PTQ, CEP and Hydrocarbon Processing.
Challenges with carbon disulfide removal in petrochemical naphtha
Energy integration of upstream and downstream units while tackling CS₂ contamination.
Optimize naphtha processing using Dividing Wall Technology
