重质糠醛精制装置携带油的回炼

重质糠醛精制装置是以糠醛为萃取溶剂,以减二、减三、减四馏份油和丙烷轻脱油为原料油的溶剂精制装置,通过糠醛萃取,得出主产品精制油和副产品抽出油,同时在生产中产生一定量的相对较轻的携带油,携带油中含有润滑油理想组份和糠醛[1]。该装置通过对携带油的回炼点的工业试验,找出携带油回炼的最好回炼点,回收携带油中的油和糠醛,为企业多创效益。

Furfural Refining Unit of Heavy Oil to Bring back Chain

Heavy furfural refining unit for the extraction solvent is to reduce the second,by three or by four oil and propane light distillate oil as the raw material oil from the solvent refining unit,through the furfural extraction,come to the main oil and refined products by-products out of oil,resulting in the production of a certain amount of carrying relatively lighter oil,lubricating oil to bring oil contains an ideal composition and furfural.The device carrying oil through the refining point back to the indus...
