The ROSE® (Residuum Oil Supercritical Extraction) process is a very efficient solvent-extraction option for recovering higher value products from resids. ROSE® units yield deasphalted oils that are excellent feedstocks for fluid catalytic crackers and hydrocrackers, as well as recover resins and asphaltenes that have a variety of uses.

ROSE units can upgrade very heavy crudes, process residue from oil sand bitumen, and extract valuable products from thermally or catalytically cracked material.

2016年12月5日 · The unit will be built using KBR's proprietary ROSE technology, which provides supercritical solvent deasphalting (SDA), and will be the largest SDA unit in the industry. Under the terms of the contract, KBR will provide the license for use of ROSE technology, as well as basic engineering design and post-start up services.

2022年11月24日 · ROSE ® stands for Residual Oil Supercritical Extraction. In the ROSE ® process, a paraffinic solvent (typically propane) in supercritical mixture is used to extract de-asphalted oil ("DAO"). The products obtained in the extraction of residuum are asphaltene, resin and de-asphalted oil.

2019年11月12日 · ROSE is a cost-effective residue upgrading process that allows refiners to upgrade a larger proportion of their low-value residue streams into high-value products and gives clients the flexibility to respond to market developments in fuel, lube and petrochemical applications as well as reduce the environmental footprint of their products.

ROSE units are usually designed for operation over a range of solvent compositions. A light-solvent unit uses propane or i-butane while a heavy-solvent unit uses n-butane or pentane. This flexibility is made possible by the similarities in the product stripping section of n-pentane/n-butane units and ibutane/propane units.
