The introduction of the Residuum Oil Supercritical Extraction (ROSE{trademark}) process in the 1970`s made it possible to design energy efficient, cost effective deasphalting units of larger capacity. This breakthrough allowed solvent deasphalting technology to be used effectively as the primary bottom-of-the-barrel upgrader in a deep conversion refinery. Today, this supercritical fluid technology is being used around the world to produce fluid catalytic cracker (FCC) feeds, lube bright stocks, deasphalted gas oil feeds for hydrotreating and hydrocracking units, specialty resins, and heavy fuel and asphalt blending components. Recent advances in supercritical separator design have led to the development of new improvements in solvent deasphalting technology that have been incorporated into ROSE units offered by Kellogg. The new separator technology provides a significant increase in capacity for existing ROSE units and lower capital and operating costs for future ROSE plants. Improved computerized methods for predicting physical and transport properties for solvent, deasphalted oil (DAO) and asphaltene components at supercritical conditions are now utilized for design. These methods allow the process designer to perform meaningful process simulation studies to ensure optimum utilization of equipment. This paper presents a short history of the ROSE technology, advantages realized by owners of ROSE units engineered by Kellogg prior to their purchase of the technology, and a discussion of recent advances in separations technology.
