The development of the oil solvent extraction industry in China is described. The first continuous oil solvent extraction plant (modeled on a Rotocel extractor) was built in 1955. Since then, other types of extractors have been installed and processes such as the desolventizing of extracted meal, the evaporation of miscella and the recovery of solvent vapor have been adopted. This essay documents improvements in technology and machinery and discusses future developments in the industry.
