| Abstract: | We had applied to the technology of structured packing and new feedstocks distributor for improving the quality of lube basic oil material and total draw rate. After this reform, the pressure drop of vacuum tower was decreased, separation precision was improved, the quality of the fourth side lube basic oil material has reached the designed specification,the quality of the second and the third side lube basic oil materical was improved,the total draw rate was highly increased.We had obtained remarkable economic benefits. |
