Solutions

More capacity. Better products. Higher margins.

Refinery process optimization plus commercially proven technologies, usually built into columns you already own.

01

Refinery Process Optimization

Raise octane and throughput using existing assets.

Find the bottleneck, quantify the opportunity, improve margins.

Capacity, margins, energy and integration, assessed across your distillation sequence. We find the constraint, then size what removing it is worth.

  • Capacity: over 40% more from a DWC Prime revamp than from high-capacity internals alone
  • Margins: isolating higher-value streams such as isopentane and food grade hexane
  • Energy: heat-pump-assisted and multi-effect distillation

20–50% CAPEX and OPEX saved across distillation sequences

02

Food & Polymer Grade Hexane

Turn an isomerization unit into a specialty-products business.

Turn a three-cut deisohexanizer into a four-product separation, pulling saleable hexane grades out of an isomerization unit that was only making octane.

  • Up to 25% more octane barrels, 8–15% more feed processed
  • Up to 50% lower energy than alternative C6 routes
  • No new columns, no additional plot space

2–12 months typical payback on a revamp

03

Hydrotreating Solutions

Add capacity and remove contaminants without expanding the hydrotreater.

New hydrotreating units, revamps and catalyst optimization. For selected services, DWC Prime™ pre-treatment removes contaminants such as CS2 ahead of the hydrotreater and avoids a costly expansion.

  • More capacity and spare capacity from existing units
  • On-spec petrochemical naphtha with reduced hydrotreater load
  • 90% iC5 premium gasoline as a second revenue stream
  • 20–50% CAPEX and OPEX reduction

Below 1 ppm CS2 without a hydrotreater expansion

Ben Prime — Benzene Saturation

Meet benzene specifications without major refinery investment.

When geography or economics rule out processing the benzene-rich stream where it is produced, Ben Prime hydrogenates it instead — in a compact liquid-phase reactor.

  • Meets gasoline benzene limits without a new C5-C6 isomerization unit
  • Over 30% more throughput from a revamped reformate splitter
  • Selective catalyst converts only benzene, minimizing octane loss

99.9% benzene saturation achievable

05

Octane Booster — Light Naphtha Isomerization

Isomerate octane is set by separation, not by the reactor. A DWC Prime retrofit inside the existing DIH shell gives that one column the extra duty.

  • 2 to 6 RON gained, reaching as high as RON 93
  • Four cuts from one existing DIH column, over 20% more unit capacity
  • No new column, no new foundations or plot space

2–12 months typical simple payback
