Study on Zhengzhou Station Transmixture Volume of Lanzhengchang Products Pipeline
Author of the article:Ding Jungang
Author's Workplace:PetroChina Oil & Gas Control Center, Beijing
Key Words: Lanzhengchang Products Pipeline; batch sequence; transmixture volume; cutting
Abstract:In the process of oil producm batch transportation,mixed oil is inevitably formed,the reduction of mixed oil becomes indispensable for oil products pipeline operation management.The paper calculates Zhengzhou Station transmixture volume of Lanzhengchang products pipeline.Through treatment and an analysis of field data about the products pipeline ,it sums up the reason of the transmixture volume at Zhengzhou station,including shutdown interface position, the valve stroke time etc. It presents the suggestion to reducing transmixture volume,with changing a manifold to the sending and receiving oil , adding a density meter outside the station, reducing the number of shutdown, calibrating density meter ,etc.
