One team, feasibility to commissioning
DWC Innovations brings together like-minded technocrats delivering state-of-the-art process technology to the oil, gas and petrochemical industries. We carry a revamp or grass-roots project end to end — identifying the opportunity, engineering the solution, supplying the proprietary internals and supporting start-up.
Turnkey & single-vendor delivery
From award to a running unit — licensing, engineering, procurement, construction support and commissioning under one roof.
In-house DWC expertise
DWC Prime, BDWC, TDWC and Dual DWC — dividing wall columns are our specialty, not a sideline.
The only commercial dual-DWC experience
The one technology partner with commercial dual dividing wall columns in operation.
Locally manufactured internals
Dividing walls, liquid splitters and vapor distributors built locally for shorter delivery.
Verified by dynamic simulation
Control schemes proven in steady-state & dynamic simulation before start-up.
Revamp specialists
Re-architect an existing column inside its shell, within a planned turnaround.
Proven dividing-wall solutions for the units where they pay back fastest — from naphtha splitting and isomerization to benzene, hexane and whole-refinery optimization.
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
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.
The full engineering scope
Every discipline a refining or petrochemical project needs — delivered by one accountable team, and available individually or as a single turnkey scope from feasibility through to start-up.
Proposal & Feasibility Studies
- Screen existing units for revamp & retrofit opportunities
- Assess technical and economic viability of each option

- Test runs for performance guarantees; energy optimisation & process tuning
Single discipline
Bring us in for one package — a feasibility study, a HAZOP, a simulation, an internals design — wherever you need specialist DWC expertise.
Basic & FEED
A firm, review-ready design basis and front-end package that de-risks your investment decision before detailed engineering begins.
Full turnkey / EPCm
One accountable vendor from feasibility to start-up — licensing, engineering, internals, procurement and commissioning, as delivered at MRPL.
Fewer columns. Lower cost. Same products.
Dividing wall columns intensify a whole separation into a single shell — the reason a DWC Prime revamp typically cuts capital, plot space and energy while making sharper products.











MRPL — a naphtha splitter revamped turnkey

CDU-2 naphtha splitter re-architected into a Dual Dividing Wall Column
At Mangalore Refinery & Petrochemicals, DWC Innovations converted the CDU-2 naphtha splitter into a Dual Dividing Wall Column using its proprietary DWC-Prime technology — delivered as a single-vendor project from feasibility through to start-up. Two dividing walls let one column make three sharper naphtha cuts — light, medium and heavy — with no change in reboiler duty, reusing the existing shell inside the plant’s planned turnaround.
A naphtha splitter can be re-architected into a multi-cut Dual DWC — sharper products, more operating flexibility and better downstream feed — with no energy penalty and inside the existing column, delivered by a single technology partner from feasibility to start-up.
Cleaner light, medium and heavy cuts give the Isomerization and CCR units better-prepared feed — debottlenecking the whole naphtha train, not just the splitter, for more valuable products across the complex.
