Houston, TX – DWC Innovations is pleased to announce the successful startup and commissioning of its proprietary DAS Splitter Dual Dividing Wall Column (DDWC) at Bharat Petroleum Corporation Limited’s (BPCL) Mumbai Refinery. The project marks a significant advancement in separation technology and represents the world’s first commercial application of a multiple-wall dividing wall column.
The installation forms a key part of the revamp of BPCL’s Lube Oil Base Stock (LOBS) Unit, and enhances process efficiency while delivering substantial reductions in equipment count, energy consumption, plot-space requirements, and overall project costs.
The innovative DDWC is capable of producing multiple lubricant grades—including D40, D80, D110, D130, and MBL—within a single integrated column system. Conventionally, achieving these separations would require a sequence of three separate distillation columns. By integrating these separations into one advanced unit, the technology delivers significant operating and capital cost advantages while maintaining exceptional operational flexibility.
Successful Commissioning of Dual DWC Prime Column at BPCL, Mumbai
This accomplishment further strengthens the longstanding relationship between DWC Innovations and BPCL. DWC Innovations previously implemented a dividing wall column revamp for BPCL’s naphtha splitting section at the Mumbai refinery, improving feed preparation for the refinery’s Isomerization and Continuous Catalyst Regeneration (CCR) units.
The successful commissioning of the DAS Splitter DDWC establishes a new benchmark in commercial distillation technology and highlights the growing role of advanced process intensification solutions in the refining and petrochemical industries.
