Low pressure coker operation with distillate recycle

Today`s highly competitive refining industry requires new and existing process units to maximize the production of high-value products while minimizing capital and operating expenses. Refiners are rapidly optimizing the design and operation of units, particularly bottom-of-the-barrel conversion units such as delayed cokers. Delayed cokers convert vacuum residues and other low-value materials into high-value liquid products along with residue gas and petroleum coke. One of the most rewarding ways to reduce low-value coke production and attain more of the high-value products from a delayed coker is to utilize the proprietary Conoco Coking Process, now available for license to industry by a joint Conoco/Bechtel Alliance team. The technology is commercially proven, as Conoco has over 40 years of coker operating experience and began licensing their coker technology in 1981. The Conoco Coking Process is based on patented technology that utilizes distillate recycle rather than the heavy, coke-producing natural recycle material used in conventional processes. Conoco`s process can reduce coke yields by approximately 10%, which corresponds to greatly improved economics. This paper is intended to address the payout and benefits of employing distillate recycle with low coke drum pressures.
