Abstract
Penelitian ini bertujuan untuk mempelajari fenomena
kenaikan titik didih dan mencari koefisien heat transfer pada
proses evaporasi larutan Na2SnO3 yang dihasilkan setelah
proses evaporasi dalam pemurnian timah dari slag timah. Data
didapatkan menggunakan metode pengukuran kenaikan titik didih
dengan variabel tekanan (760, 720, 680, 640, 600, 560, 520, 480,
440, 400, 360 mmHg) dan variabel konsentrasi larutan Na2SnO3
(50%, 40%, 30%,25%, 20%, 10% berat). Harga kenaikan titik
didih rata-rata dari larutan Na2SnO3 dengan konsentrasi 10%,
20%, 25%, 30%, 40%, dan 50% secara berurutan adalah
1,13 oC; 2,26 oC; 2,96 oC; 3,19 oC; 3,85 oC; dan 4,59 oC. Harga
koefisien perpindahan panas konveksi rata-rata dari pendidihan
larutan Na2SnO3 dengan konsentrasi 10%, 20%, 25%, 30%, 40%,
dan 50% secara berurutan adalah 3457,23; 3904,90; 4250,02;
4498,20; 4965,90; dan 5688,50 W/m2 K

This research is established to study mainly the
phenomena of the boiling pint elevation and the calculation of
heat transfer coefficient in the boiling process of Na2SnO3
solution that produced after going through the evaporation
process to purify tin from tin slag. Pressure variable (760, 720,
680, 640, 600, 560, 520, 480, 440, 400, 360 mmHg) and Na2SnO3
solution concentration variable (50%, 40%, 30%, 25%, 20%,
10% weight) is used to collect data using measurement of boiling
point elevation method. From the research we got the average
boiling point elevation of Na2SnO3 solution, with a
concentration of 10%, 20%, 25%, 30%, 40%, and 50%
sequentially is 1,13 oC; 2,26 oC; 2,96 oC; 3,19 oC; 3,85 oC; and
4,59 oC. The average heat transfer coefficient of Na2SnO3
solution with a concentration of 10%, 20%, 25%, 30%, 40%, and
50% sequentially is 3457,23; 3904,90; 4250,02; 4498,20;
4965,90; and 5688,50 W/m2 K
