Abstract
MP Separator di CPP unit akan memisahkan hydrocarbon gas dari minyak dan air. Ketika temperature output hydrocarbon gas dari MP Separator terlalu tinggi yaitu sebesar 62 °C–70 °C maka akan meningkatkan potensi shutdown MP Compressor. Maka dari itu perlu ditambahkan new cooler tipe shell and tube dengan media pendingin air untuk menurunkan temperature output hydrocarbon gas menjadi 45 °C. Shell and tube memiliki dimensi 2 shell dengan diameter 44”, 1200 tube dengan panjang 9.9 meter dan diameter 1”. Lalu dilakukan perancangan sistem pengendalian temperature pada shell and tube dengan memberi pengendali PI yang diperoleh dari metode kurva reaksi dengan Kp 17.27 dan τ_i 2.21. Performansi yang diperoleh yaitu rise time sebesar 14 detik, settling time sebesar 26.3 detik, serta overshoot sebesar 0 %. Mode pengendali PI mampu beradaptasi ketika diberikan variasi berupa perubahan mass flowrate air, temperature inlet hydrocarbon gas, dan temperature inlet air. ==================================================================================================================================
MP Separator in the CPP unit will separate the hydrocarbon gas from oil and water. When the hydrocarbon gas output temperature of MP Separator is too high at 62 °C – 70 °C it will increase the potential for MP Compressor shutdown. Therefore it is necessary to add a shell and tube type with water cooling media to reduce the hydrocarbon gas output temperature to 45 °C. Shell and tube has dimensions of 2 shells with 44" of diameter, 1200 tubes with a length of 9.9 meters and a diameter of 1". Then a shell and tube temperature control system design was carried out by giving PI controllers obtained from the reaction curve method with Kp 17.27 and τ_i2.21. The performance obtained is a rise time of 14 s, a settling time of 26.3 s, and overshoot of 0 %. PI controller mode is able to adapt when given variations in the form of changes in water mass flowrate, temperature inlet of hydrocarbon gas, and temperature inlet of water.
