Abstract

Penelitian ini bertujuan mengkaji secara eksperimen tentang proses pemisahan sistem aspal — kerosin dalam tangki distilasi batch yang dioperasikan secara vakum dan mengestimasi harga coefocient overall heat transfer (U) serta menetukan kebutuhan bahan bakar LPG . Dalam penelitian eksperimen ini tangki distilasi dilakukan dengan kondisi vakum untuk menurunkan titik didih dari solvent agar lebih cepat menguap. Variasi tekanan vakum dalam penelitian ini yaitu -10, -15, dan -20 cmHg, kadar bitumen sebagai feed dalam tangki distilasi divariasi 10 Yo dan 18 % Dari penelitian ini diperoleh bahwa semakin tinggi tekanan vakum didalam tangki distilasi maka waktu dsitilasi lebih singkat. Semakin tinggi konsentrasi larutan aspal maka waktu distilasi semakin lama. Semakin tinggi tekanan vakum maka distribusi kenaikan suhu liguid semakin cepat. Kenaikan distribusi juga meningkat seiring dengan menurunnya konsentrasi larutan. Nilai Coefficient Overall Heat Transfer pada konsentrasi 10% untuk tekanan -10 cmHg, -15 cmHg dan -20 cmHg adalah 0,166 W/m?.K, 0,116 W/m2.K dan 0,083 W/m'.K. Sedangkan pada konsentrasi 18% untuk tekanan -10 cmHg, -15 cmHg dan -20 cmHg adalah 1,58 W/m?.K, 1,083 W/m?.K dan 0,833 W/m'.K. Sehingga diperoleh persamaan koefisien perpindahan panas U = 0,00022 C'“7 ps4 Kebutuhan LPG yang digunakan untuk bahan baku larutan aspal 1 kg sebanyak 0,22 kg.

This study aims to examine experimentally the process of separating systems asphalt - kerosene in batch distillation tank is operated in a vacuum and estimate the overall coefficient of heat transfer rates (U) as well as determine the need for LPG fuel. In this experimental study conducted by the distillation tank under vacuum to lower the boiling point of the solvent to evaporate more quickly. Vacuum pressure variation in this study are -10, -15, and -20 cmHg, bitumen content as a feed in a distillation tank varied by 10% and 18%. Of this study was obtained that the higher pressure inside the tank vacuum distillation then dsitilasi shorter time. The higher concentration tar distillation then the longer time. The higher the vacuum pressure distribution liquid the faster the temperature rises. The increase in distribution also increases with decreasing solution concentration. Overall Heat Transfer Coefficient values at concentrations of 10% for the pressure of -10 cmHg, -15 cmHg and -20 cmHg was 0.5 W/m2.K, 0.4167 and 0.25 W/m2.K W/m2.K. Meanwhile, at a concentration of 18% for the pressure of -10 cmHg, -15 cmHg and -20 cmHg are W/m2.K 1.667, 1.08 and 0.833 W/m2.K W/m2.K. Thus obtained the equation of heat transfer coefficient U = 0,00022 C***”” p1?!4 Demand of LPG is used for 1 kg of raw materials asphalt as much as 0,22 kg.
