Action: Change kero/gas oil operation to kero/diesel operation
Preparing an Operating Program
In present day refining industry, both the running plan and the subsequent operating
programs are computerized. However, their preparation requires the same input as
the old manual system. In the case of the operating program, these would follow the
sequence listed below:
1. In order to begin assembling the operating program, the planner will need to
know the following details:
• The running plan for the refinery for the month in question.
• The latest crude slate data.
• What plants are scheduled for shutdown during the life of the program?
• Estimate of the intermediate product stocks (Appendix 3).
2. Prepare an outline operating schedule to meet intermediate product requirements
and timed to maintain adequate intermediate products in tankage (Appendix 4).
3. Cut the crude(s) TBP into the required product cuts, for the crude unit operation.
4. Cut the product from the other units (such as FCCU and cat reformer) to meet
intermediate products.
