Independent Process Engineering
Distillation and separation · Gas processing · Relief and flare systems · Hydrogen and carbon capture
Advanced Process Design Ltd provides specialist process engineering to EPC contractors, engineering consultancies, developers and plant operators.
We take defined work packages and independent design reviews, from feasibility and FEED through to column revamps, brownfield modification and commissioning support. Useful when a project needs senior process input without adding permanent headcount.

Distillation and Separation Specialists
Most consultancies can produce a PFD. Fewer can tell you why a column is weeping, or design a cryogenic scheme that tolerates CO2 rather than paying for an amine unit upstream.
- Column design, rating and internals selection in structured and random packing
- Capacity and efficiency revamps
- Diagnosis of flooding, weeping and off-specification operation
- Cryogenic separation: demethanisers, NGL recovery, nitrogen rejection, CO2 liquefaction
- Licensed process design packages for nitrogen rejection units up to 300 MMSCFD
Backed by a doctorate in process integration and published papers on distillation and separation design.
