Abstract
Permasalahan industri dalam penentuan suhu fluida pada proses pemanasan menggunakan heat exchanger tipe shell and tube dapat diselesaikan dengan pemodelan dan simulasi. Pemodelan berupa persamaan perpindahan panas secara konduksi dengan kondisi operasi steady-state dan sistem continuous, serta simulasi menggunakan sub-routine pdepe pada MATLAB. Penelitian ini bertujuan menentukan pemodelan dan simulasi untuk mengestimasi suhu keluar raw oil dan menentukan profil suhu fluida sepanjang tube. Pemodelan secara fisik heat exchanger sesuai data sekunder PT. PERTAMINA BALONGAN, dengan perpindahan panas yang membagi heat exchanger menjadi 10 bagian dari q1 hingga q10. Fluida pemanas yaitu net bottom oil yang dialirkan pada tube dan fluida yang dipanaskan yaitu raw oil dialirkan pada shell. Data sekunder dan hasil simulasi divalidasi dengan uji-t. Hasil pemodelan dan simulasi diperoleh profil suhu fluida sepanjang tube, konduktivitas termal, kapasitas panas dan fluks panas. Pemodelan dan simulasi mampu mengestimasi suhu keluar raw oil dengan simpangan deviasi sebesar 2,55 dari suhu keluar raw oil data. Penggunaan asumsi linier pada profil suhu fluida memiliki perbedaan perubahan suhu sepanjang tube, dengan profil suhu net bottom oil memiliki gradien penurunan suhu sebesar -20,29 °C/m yang lebih besar dari gradien kenaikan suhu pada profil suhu raw oil yaitu sebesar -2,92 °C/m.
English Abstract
Industrial problems to determining the fluid temperature of heating process using a shell and tube type heat exchanger may solve by modeling and simulation. The modeling use conduction heat transfer equations with steady-state operating conditions and continuous systems, simulations use the pdepe sub-routine in MATLAB. The research determine the modeling and simulation to estimate the out temperature of raw oil and determine the temperature profile of the fluid along the tube. Physical modeling of heat exchanger according to secondary data of PT. PERTAMINA BALONGAN, heat transfer divide the heat exchanger into 10 sections from q1 to q10. The heating fluid is net bottom oil which flows into the tube and the heated fluid is raw oil which flows into the shell. Secondary data and simulation results were validated by t-test. The results of the modeling and simulation obtained profiles of fluid temperature along the tube, thermal conductivity, heat capacity and heat flux. Modeling and simulation are able to estimate the raw oil’s out temperature with a deviation of 2.55 from the raw oil’s data out temperature. The using of linear assumptions on the fluid temperature profile has a difference in temperature changes along the tube, with the net bottom oil temperature profile having a temperature gradient of -20.29 °C/m which is greater than the gradient of temperature increase in the raw oil temperature profile of -2, 92 °C/m.
