| 1 | Technology for Coking of Heavy Crude Oil with High Acid Number显示文摘Sudan Khartoum Refinery Co. has selected a unique route featuring delayed coking of crude in connection with the highly sour and high-calcium heavy crude extracted from Sudanese oil block No. 6.The crude oil after pretreatment for calcium removal is subjected to coking for removal of acids and metals with the coker products being further processed. The crude oil extracted from Sudanese oil block No. 6contains as high as 13 mg KOH/g of crude in addition to a calcium content of 1600 ppm. This article makes an analysis on problems related with the operation of commercial delayed coking unit for processing of highly sour crude and bring forth measures to solve these problems. The liquid yield resulted from coking of crude oil can reach 82m%, and the petroleum coke can meet the quality requirement for class 3B petroleum coke. | JiangWen ZhaoYujun ChengGang LiChao ShenHaiping CuiLong | 2005 | China Petroleum Processing & Petrochemical Technology2005，7，1： | 4 |
