BMCI control of hydrocracking unit tail oil
Thread Content
There are many factors related to the tail oil in the hydrocracking unit, but what is the most important factor affecting the BMCI of the tail oil? I hope everyone can express their opinions more
The most important factors affecting tail oil BMCI are:: 1. Nature of raw materials ； 2. Reaction temperature ； 3. One-way conversion rate: 4. Catalyst performance.
It is required that the BMCI value of hydrocracking tail oil cannot exceed 20, and generally less than 10 is preferred. The greater the reaction depth, the lower the BMCI value and the higher the ethylene yield.
Research on steam cracking performance of hydrocracking tail oil (China Chemical Society 2003 Petrochemical Academic Annual Conference) This article provides a good analysis
