A Network of Dividing Wall Columns for Whole-Train Process Intensification
This white paper from DWC Innovations describes the first commercial installation in which a network of four dividing wall columns replaces an entire seven-column separation train — here in an
Latest Whitepapers.
Optimize Naphtha Block
This whitepaper from DWC Innovations examines how dividing wall column (DWC) technology can upgrade naphtha block performance in refineries. Full-range naphtha — a broad hydrocarbon cut…
Upgrade Naphtha Products
This DWC Innovations whitepaper examines how a dividing wall column can upgrade a refinery’s naphtha pool by revamping an existing depentanizer. The facility needed three separated…
Debottleneck Distillation Columns Using DWC Prime
This DWC Innovations whitepaper presents a case study on revamping bottlenecked naphtha splitter columns with dividing wall column technology at a major South East Asia refinery.…
“One dividing wall column does the work of two — up to 50% less CAPEX, energy and plot space.”
Maximize Margins in Light Naphtha (C5-C6) Isomerization Unit by Producing Additional C6 Products
This DWC Innovations whitepaper examines how dividing wall column (DWC) technology can revamp isomerization units to boost margins from light-naphtha feed. Isomerization upgrades C5/C6 octane and…
CS2 removal to meet new specifications for Petrochemical Naphtha
Petrochemical naphtha (PCN) is an increasingly valuable feedstock for ethylene crackers, but stringent carbon disulfide (CS2) limits are hard to meet — CS2 irreversibly poisons hydrotreating…
Boost Octane and Throughput of C5 Isomerization Units
This DWC Innovations whitepaper explains how dividing wall column (DWC) technology can boost octane and throughput in light-naphtha isomerization units. Conventional once-through isomerization typically yields a…
