D.S.J. Jones Note: The names and location of the company and its refineries are,
of course, fictitious. The study though is not. The author actually participated in the
study itself and was later the lead engineer in the process design of one of the
selected refinery (Case 6A) debottlenecking expansions.
A copy of one work sheet used in the study is given in Appendix 1 of this
chapter. Most calculations at that time were done by hand, although the discounted
cash flow calculations were computerized.
The Refinery Operating Program
One of the major uses of the running plan is to enable the refineries of the company
to develop their own operating programs. The running plan sets the objective for the
refinery production over a short term and provides a long-term forecast. The
operating program translates these requirements into a day-by-day program of
work. Operating programs are concerned about the short-term plans for the operation and are prepared for a monthly period. Thus, while running plans are
calculated in terms of barrels per calendar day, operating programs are always in
terms of barrels per stream day.
The Content of the Operating Program
The actual format of operating programs will vary from company to company;
however, they will follow a similar pattern. They will consist of the following items:
• A crude oil program
• An intermediate stock report
• A table of programmed production
• A blending schedule
• An operating schedule
• Operating notes
A crude oil program is a table of the refinery’s current crude oil inventory with
projected imports, feed outlets, and the storage tank reference. An example of this
table is given as Appendix 2 of this chapter.
An intermediate stock report is similar to the crude oil program, but it refers to
the refinery’s intermediate stocks, which will usually be blended to finished products. An example of this table is also given as Appendix 3.
The table of programmed production is simply the scheduled finished product
make from the refinery. The blending schedule is self-explanatory and is usually in
a form of simple block flow diagrams. A typical middle distillate schedule is given
in Fig. 2.
Operating notes include any critical requirements or operational changes. Operating notes can be updated on a weekly or even daily basis if the company’s supply
department initiates a change in running plans that affect a particular refinery’s
operating program. An example of an operating note is as follows:
