Abstract
PT. SAKA Indonesia Pangkah Limited memiliki permasalahan di unit CPP yaitu naiknya temperatur hydrocarbon gas dari MP Separator ke MP Compressor pada rentang 62°C - 70°C yang akan menyebabkan temperature discharge mencapai 170°C. Sedangkan jika temperature discharge mencapai 170°C, sistem akan mengalami shutdown. Untuk menghindari sistem mengalami shutdown, pada penelitian ini dipilih refrigerant cooler untuk menurunkan temperatur hydrocarbon gas. Di dapatkan dimensi refrigerant cooler dengan jari-jari 0,6 m dan tinggi 2,59 m. setelah itu dilakukan perancangan sistem pengendalian guna menjaga keluaran temperatur hydrocarbon gas dari masukan temperatur hydrocarbon gas yang fluktuatif. Di dapatkan pengendali terbaik yaitu PI dengan nilai Kp = -17,5, dan Ti = -1,809. Di dapatkan parameter rise time 26,6 s, overshoot 0% dan settling time 55,9 s.

PT. Saka Indonesia Pangkah Limited has a problem that increasing hydrocarbon gas temperature on CPP Unit, from MP Separator to MP Compressor on 62°C - 70°C range which causes discharge temperature reaches 170 oC. If discharge temperature reanches 170 oC, system will get shutdown. To prevent a shutdown, on this research we will be choosing a refrigerant cooler to reduce hydrocarbon gas temperature. This research results that the dimension of refrigerant cooler has 0,6 m radius and 2,59 m height. After that, we designed the temperature control system to keep hydrocarbon gas temperature at set point from fluctuating inlet temperature of hydrocarbon ga. This research results that the best controller is PI mode with a Kp value of -17,5 and a Ti value of -1,809. It performances 26,6 s of rise time, 0% overshoot and 55,9 s of settling time.
