KBR announces selection of its ROSE® technology by Total.

KBR has announced that its ROSE® solvent deasphalting technology has been selected by Total for use at its refinery in Antwerp, Belgium.

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® technology is based on the use of a light, readily available paraffinic solvent to extract deasphalted oil from a feedstock rich in asphaltenes. The solvent is separated from the deasphalted oil in the downstream deasphalted oil separator, then recovered and recycled. Solvent selection is based on the desired deasphalted oil purity and yield for a given feedstock. The ROSE unit includes a deasphalted oil stripper and an asphaltene stripper for final recovery and recycling of dissolved solvent from the two effluent streams.

In this instance, the ROSE® technology will split 48 000 bpd of residue from a mix of crude oils into deasphalted oil (DAO) and asphaltene. The DAO will be upgraded in a mild hydrocracking unit and the asphaltene will be blended into fuel oil.

The unit is expected to significantly enhance the profitability of the refinery. It is expected to come onstream in early 2016.

John Derbyshire, President of KBR Technology, has outlined KBR’s delight in being selected by Total for this major project. Derbyshire has additionally expressed that KBR are confident that the project will enable Total to achieve its business objectives.
