Abstract

A step-by-step procedure was obtained in optimizing the utility and process by working inwards of onion model diagram. The process plantused in the case study is the palm oil refinery, whilethe utility is the steamgeneration withturbo generator. Utility system was the first part that beingoptimized since the source of energy is coming from this system. From the optimization of utility, the marginal steam pricing plot was constructed to visualize the scope of saving as a result of steam saving at the process site. The energy saving of the process was obtained by working outthe difference of the existing to the minimum heating requirement. The amount of steam saving then used to determine the scope of saving by referring to the marginal steam pricing plot which is at $32,326.44/year. A retrofitting of the heat exchanger network was made and the estimated capital cost of installing new heat exchanger, covering the needed area was about $123,266.24. The payback period for investing the new heat exchanger with the scope saving obtained is about 4 years.
