This research discusses the optimization of Platformer Heater design on PT platforming units.
X with additional Sweet Naphtha processing capacity. The main objectives of optimization are to
increase energy efficiency, maintain reaction temperature stability at an optimal level, and overcome
limited heating capacity which has the potential to cause operational problems such as flame
impingement and overfiring. The research method includes Platformer Heater efficiency analysis and
heat duty calculations carried out using Microsoft Excel. The operational data analyzed shows that the
heating power requirement (Total Required Heater Duty) for the five interheaters has increased
significantly after the after conditions compared to the before conditions. The efficiency of each
interheater is in the range of 70% to 72%, while the efficiency of the Platformer Heater is in the range
of 70% to 80%. Even though efficiency between devices is relatively stable, this increase in heating
power requirements indicates an increase in workload or changes in operational conditions that require
these devices to use more power to continue functioning optimally. For example, interheater 2 requires
heating power of 139,967 Btu/hr in the before condition, which then increases to 221,614 Btu/hr in the
after condition. This confirms that changing conditions affect the amount of energy required for heating,
so it is important to consider this in planning and operating the heating system so that efficiency and
performance are maintained. This study also emphasizes the importance of controlling Mean Beam
Length and gas emissivity as key factors in increasing heater efficiency. Economic evaluation based on
Total Capital Investment and Operating Cost.
