摘要
介绍了重质油超临界流体萃取分馏的原理及特点,论述了超临界流体技术在分离渣油、精制石蜡和制备中间相沥青中的应用,说明了超临界流体萃取分离技术在重质油深度加工中具有的优势。开发利用该技术将有利于进一步合理利用重质油,提高轻质油收率,获得较好的经济效益。
The principles and characteristics of the supercritical fluid extractive fractionation for heavy oil were introduced.The application and advantages of separating residue oil, purifying paraffin wax and preparing mesophase asphalt by the supercritical fluid technology were discussed and analyzed. The results showed that the development and use of this new technology could use the heavy oil reasonably,increase the yield of light oil and gain good economical benefits.
