Abstract
Skripsi ini membahas tentang effektivitas pada alat penukar kalor berupa cooler yang nilainya ditentukan dengan menggunakan Metoda Analisa energi. Selain itu juga dilakukan perhitungan beban kalor, koefisien perpindahan panas pada tube dan shell, koefisien perpindahan panas total, penurunan tekanan yang teijadi di tube dan shell, luas perpindahan panas total, LMTD ( Log Mean Temperature Difference ), dan cleanliness factor pada beberapa kondisi operasi. Data kondisi operasi diambil di PT. PUSRI, Palembang. Dari hasil perhitungan dapat disimpulkan bahwa nilai koefisien perpindahan panas total berbanding lurus dengan effektivitas dari alat penukar kalor. Alat penukar kalor yang dikaji adalah alat penukar kalor tipe shell and tube ( Methanator Effluent Cooler ) dengan fluida kerja cooling water ( air pendingin ) pada sisi shell dan fluida kerja methane pada bagian tube. Dengan LMTD ( Log Mean Temperature Difference ) = 32,977 °C ( Kondisi A ), diperoleh nilai effektivitas sebesar 0,961 dan cleanliness factor 0,79. Dengan LMTD = 32,7222 °C ( Kondisi B ), diperoleh nilai effektivitas sebesar 0,96 dan cleanliness factor 0,79.Dengan LMTD = 32,26 °C diperoleh nilai effektivitas sebesar 0,958 dan cleanliness factor 0,79. Nilai Cleanliness factor yang baik adalah lebih besar atau sama dengan 0,85 maka disarankan agar heat exchanger tersebut dilakukan pembersihan ataupun re-tubing, agar performansi alat dapat meningkat.
