FIS-483 Consolidated Engineering Study Report

Marathon Petroleum Company, Catlettsburg Refinery, KY
Capacity Improvement Study of LPCCR Platformer Heater (1-44-B-1/2/3/4)
This revamped design of the heater with new convection section will increase the
charge rate capacity of the heater to 24.5 MBPD. We have sized the heater for
the permitted firing rate of 280 MMBtu/hr (LHV). The total absorbed heat duty is
246.5 MMBtu/hr. The total process duty is 191.7 MMBtu/hr. Debutanizer heat
duty is 5.12 MMBtu/hr and Waste heat duty is 49.63 MMBtu/hr.
The table below shows the comparison of existing design, maximum charge case
and proposed design heat duties and the percentage flow through split flow coils:

Total Duty 106.3 134.7 191.7 57.0
The process heat duty is being increased by almost 85.4 MMBtu/hr from the
existing design heat duty and about 57 MMBtu/hr from the current operating levels
of 134.7 MMBtu/hr.
1.5 Cost Estimation
FIS has developed ±30% cost estimates for Platformer Heater(1-44-B-1/2/3/4)
revamp. The estimated cost for the proposed recommendation is $ 9.99 Million.
The cost includes design engineering supply and erection of the new convection
section. It also includes split flow piping and instrumentation.
We hope you find our report helpful and informative. We will provide you all the help
you need in implementing these changes. We will be happy to provide you with
follow up support, should you need further information or clarifications.
