Engineering & Optimization Services
From troubleshooting to start-up. We help refiners, petrochemical and chemical producers solve process challenges, evaluate opportunities and execute projects.
Our refinery engineering services help refiners and chemical producers get more from the assets they already have. Whether the goal is more throughput, lower energy use, better product quality or a new separation technology, we support projects from the first study through commissioning.
How Can We Help?
My unit is capacity-limited
Debottlenecking studies, hydraulic analysis, optimization and revamp engineering.
Start here →My column is flooding or off-spec
Find the real bottleneck with plant data, simulation and equipment rating.
Start here →I need a feasibility study
Options, economics, capital and operating cost, and payback before you commit.
Start here →I want more valuable products
Extra cuts and sharper separations from the assets you already have.
Start here →I need a complete project
Feasibility through engineering, procurement support, start-up and commissioning.
Start here →Services That Improve Refinery Performance
Distillation Optimization
Increase capacity, improve product quality and reduce energy use through troubleshooting, hydraulic analysis and targeted revamps.
Typical projects
- Distillation troubleshooting
- Flooding studies
- Capacity expansion studies
- Product quality improvement
- Energy optimization
- Trial-run support
Refinery Debottlenecking
Find the true bottleneck before spending capital. We evaluate columns, exchangers, pumps and utilities to find the lowest-cost path to more production.
Typical outcomes
- Higher throughput
- Additional spare capacity
- Lower project cost
- Better asset utilization
Process Simulation & Modeling
Rigorous, plant-calibrated process models for studies, optimization and technology evaluation.
Services include
- Steady-state and dynamic simulation
- Process optimization
- Heat integration studies
- Technology evaluations
- New process development
Proposal & Feasibility Studies
Is the project worth doing? We review the process and equipment, identify the real constraints and put numbers against the options before capital is committed.
Deliverables
- Process and equipment review
- Preliminary utility and capital cost estimates
- Economic evaluation with ROI projection
- Payback evaluation
Revamp Engineering
Improve performance without building new units, through internals upgrades, equipment changes, better controls or process redesign.
Typical revamps
- Distillation columns
- Naphtha splitters
- Deisohexanizers
- Hydrotreaters
- Recovery systems
Basic Engineering
The bridge between a feasibility study and detailed design: the package that transfers our process technology and know-how to your team.
Deliverables
- PFDs, P&IDs and material balances
- Equipment specifications and utility requirements
- Control philosophy and safety analysis
FEED Package
Front-end engineering design firm enough to commit capital against, for grassroots facilities or brownfield expansions.
Deliverables
- Process flow diagrams and equipment specifications
- Utility and instrumentation requirements
- Cost estimate and project execution schedule
Detailed Engineering
FEED becomes Issued for Construction: everything procurement, construction and commissioning teams need to build what was designed.
Deliverables
- IFC P&IDs, 3D models, E&I and civil/structural design
- Construction work packages and cost estimates
- Operating manuals and commissioning procedures
Start-up & Technical Services
The same engineers follow the design through commissioning, start-up and early operation.
Services include
- HAZOP studies and field inspections
- Operator training
- Start-up support
- Performance guarantee test runs
- Troubleshooting and optimization after start-up
Technology Licensing
Implementation of DWC Innovations’ proprietary technologies, from licensing through start-up.
DWC technologies →Need advice, not a project?
Process consulting gives your team independent technical support for troubleshooting, process simulation, technology selection, design review and optimization studies.
Why Clients Choose DWC Innovations
Lowest-cost path first
Practical solutions before capital projects.
Simulation plus plant experience
Recommendations grounded in modeling and operating reality.
Proven refinery expertise
Projects across refining, petrochemicals and chemicals.
Technology and engineering under one roof

Long-term partnership
From feasibility through start-up and optimization.
Proven Optimization Results
Mixed pentane on spec
An Indian refinery made on-spec mixed pentanes from an existing two-column unit within two days of starting the plant trial.
Hexane unit debottlenecked
High-capacity trays, a parallel reboiler and upgraded reflux pumps, with no unnecessary equipment replacement.
Isopentane added
A heating-medium change and a reflux pump impeller modification instead of a unit revamp.
Commercial Results That Matter
Dividing wall columns commercialized worldwide.
World’s first commercial multi-wall DWC, at BPCL Mumbai.
World’s first multi-column DWC network. See the case studies.
