In order to overcome these problems, the flow schemes as shown in Figures 1 and 2 were developed. These incorporate the use of Kerr-McGee Corporation s Critical Solvent Deashing and Fractionation Process (CSD) for recovery of the SRC. The Kerr-McGee Process adds extra flexibility since this process can recover heavy solvent for recycle, which is not recoverable by vacuum distillation. EPRI contracted with Conoco Coal Development Company (CCDC) and Kerr-McGee Corporation in 1977-1978 to test these process concepts on continuous bench-scale units. A complementary effort would be made at the Wilsonville Pilot Plant under joint sponsorship by EPRI, DOE, and Kerr-McGee Corporation. This paper presents some of the initial findings. 

ROSE (1) [Residuum Oil Supercritical Extraction] A process for extracting asphaltenes and resins from petroleum residues, using supercritical propane or isobutane as the extractant. Developed by Kerr-McGee Corporation in 1979 and sold to the MW Kellog Company in 1995, at which time 25 units had been licensed. 

Anhydrous horax is made from its hydrated forms by calcination and fusion. In the United States, it is produced by US Borax and Kerr-McGee Corporations. The starting material is horax decahydrate. The amorphos form is obtained by rapid cooling of molten borax. The molten material on long standing produces the crystaUine form. 

Commercial hydroxyapatite sample No. 1 was Biogel HTP from Biorad Laboratories. Commercial Sample No. 2 was obtained from the Kerr-McGee Corporation.

Leonard, Garwin, Gearhart, and Roach are names that appear liberally in the next few patents. They invented many variations of the basic ROSE process for Kerr-McGee Corporation. After having discussed the basic ROSE process operation in Chapter 7, we have selected other variations of the process to serve as addidonal teaching tools. 

As an example of the acid-leaching, solvent extraction class of uranium-concentration processes, a description will be given of the process used in the large uranium mill of the Kerr-McGee Corporation at Grants, New Mexico. This has been condensed from a 1960 paper by Hazen...

An advanced version of solvent deasphalting is residuum oil supercritical extraction, or ROSE. The ROSE Process was developed by the Kerr-McGee Corporation and now is offered for license by KBR Engineering and Construction, a subsidiary of Halliburton. In this process, the oil and solvent are mixed and heated to above the critical temperature of the solvent, where the oil is almost totally insoluble. Advantages inelude higher recovery of deasphalted liquids, lower operating costs due to improved solvent recovery, and improved energy efficiency. The ROSE process can employ three different solvents, the choice of which depends upon process objectives Propane Preparation of lube base stocks...
