LC-Max incorporates RSR or ROSE SDA between Stage 1 and Stage 2 LC-Fining
The Chevron Lummus Global (CLG) markets its own RSR (Residue Solvent Refining) SDA technology and integrates it within its LC-MAX® residue upgrading package.
At the engineering and process level, RSR is a commercial variant of ROSE: CLG formally sub-licenses the ROSE technology from KBR, with KBR providing technology licensing, basic engineering design, and proprietary equipment for the SDA portion of every CLG RSR LC-MAX project.
