ROSE PROCESS IMPROVES RESID FEED

A new economical approach to residuum processing has been developed and is known as the ROSE (Residuum Oil Supercritical Extraction) process. The new process was developed by Kerr-McGee Refining Corp., and it involves the use of a variety of selective solvents for extraction treatment of reduced crude oils and vacuum residues. The major portion of the development work was done with pentane as the solvent. Yet the solvent selection is made in accordance with the nature of the feedstock and the objectives to be achieved with respect to end products. A unique feature of the process is the more economical recovery of the solvent under supercritical conditions instead of by conventional evaporation. This feature alone results in a utility saving of about 50 percent over the usual evaporative method. Investment savings of about 20 percent are also typical. The solvent-extracted oil, at a given recovery, is lower in carbon residue and metals than is vacuum flashed oil. High yields of oil are possible, even from waxy stocks and very heavy residues.
