摘要
本工作用溶剂萃取法从炭泥中回收增塑剂,通过小试筛选最佳的溶剂,确定工艺条件;在年产百万吨级的工业装置上进行生产性试验,结果为抽出率达炭泥量的50％以上,溶剂回收率达90％以上,回收的增塑剂产品达到部标二级品标准.
A method of retrieving plasticizer from activated carbon mud by solvent extraction has been developed. The extracted rate of plasticizer exceeds 50% of the activated carbon mud, the solvent recovery reaches 90% and the quality of reclaimed plasticizer products is suitable to the standards concerned.
