Analysis Heat Exchanger Network Steam Power Plant in Using Pinch (Case Study in PT POMI Unit 3 Power Plant Paiton)

PT. POMI Paiton Unit 3 is one of big steam power plant in Indonesia that provide electricity with a capacity of 1 x 815 MW. This power plant requires a large amount of coal to produce electricity with a lot of large quantities, estimates of the total consume coal amounted to 3.06 million tons / year. The performance of the power plant PT. POMI Unit 3 can be optimized by modifying the Heat Exchanger Network (HEN). Pinch method is used to optimize HEN, this method provides a good opportunity in the design or in evaluating HEN system. Research has been carried capable increase efficiency of 0.5% of the power plant that was originally 28.45% to 28.95%, and can reduce fuel use by 1.71 kg / s initially as much as 97.99 kg / s to 96.28 kg / s, and can also be reconstructed from the re-arrangement of Heat Exchanger Network of Power Plant PT. POMI Unit 3 Paiton.
