Abstract

Problem table analysis adalah metode kuantitatif dalam teknologi pinch untuk menghitung kebutuhan minimum panas (hot utility) dan pendinginan (cold utility) pada sistem termal industri. Dengan menyusun data suhu dan entalpi dalam bentuk tabel, metode ini membagi fluida ke dalam interval suhu berdasarkan ΔTmin, lalu menghitung surplus atau defisit energi di setiap interval melalui neraca entalpi. Hasil divisualisasikan sebagai heat cascade untuk menentukan titik pinch dan batas pemanfaatan panas internal. Analisis pada ΔTmin 10–28°C menunjukkan bahwa semakin besar ΔTmin, semakin besar kebutuhan hot utility, sementara cold utility mengalami fluktuasi akibat variasi distribusi panas, karakteristik stream dan konfigurasi aliran. Pemilihan ΔTmin yang tepat penting untuk menyeimbangkan efisiensi energi internal dengan konsumsi energi eksternal, guna mencapai desain jaringan penukar panas yang optimal, efisien dan ekonomis.
