Abstract

Penelitian ini bertujuan untuk mempelajari pengaruh parameter operasi seperti temperatur reaktor dan laju alir pelumas (LHSV) terhadap penjenuhan dan pengurangan senyawa sulfur minyak pelumas dalam reaktor hidrogenasi aromatik dan hidrodesulfurisasi. Selain itu, penelitian ini juga bertujuan untuk menentukan kondisi optimum dari variabel percobaan yang digunakan. Penelitian ini menggunakan software ASPEN PLUS V8.8. Penelitian ini menggunakan 2 variabel tetap, yaitu tekanan 21 bar dan rasio Gas-to-oil 250 L/L. Penelitian ini menggunakan 2 variabel bebas, yaitu suhu 300oC; 310 oC; 330 oC; 350 oC; 370 oC; 390 oC dan Liquid Hourly Space Velocity (LHSV) 0,5 jam-1; 1 jam-1; 1,5 jam-1; 2,75 jam-1; 3,75 jam-1. Penelitian ini menggunakan proses sekuensial antara hidrogenasi aromatik (HDA) kemudian hidrodesulfurisasi (HDS) dan reaktor bersifat adiabatis. Dari penelitian yang telah dilakukan, didapatkan kesimpulan sebagai berikut. Pada suhu dibawah 350oC, yield senyawa jenuh hasil reaksi HDA meningkat seiring dengan meningkatnya suhu operasi, sementara pada suhu di atas 350oC yield senyawa jenuh hasil reaksi HDA menurun sering dengan meningkatnya suhu. Yield senyawa jenuh hasil reaksi HDA menurun seiring dengan meningkatnya LHSV. Konversi reaksi HDS meningkat seiring dengan meningkatnya suhu. Konversi reaksi HDS menurun seiring dengan meningkatnya LHSV. Kondisi operasi optimal reaksi HDA pada suhu 350oC dan LHSV 0,5 jam-1 sedangkan reaksi HDS pada suhu 390oC dan LHSV 0,5 jam-1. ========================================================================================================================The purposes of this research are to evaluate the effect of operating condition and parameter such as reactor temperature and liquid hourly space velocity (LHSV) on the saturation process and desulphurization process of used lube oil in hydrogenation of aromatic (HDA) and hydrodesulphurization (HDS) reactor and to find their optimum condition based on experiment’s process variables applied. The research was modelled by using ASPEN PLUS V8.8 software with hydrogenation of aromatic reactor and hydrodesulphurization reactor were both arranged sequentially and operating adiabatically. 2 constant variables and 2 independent variables were applied. These 2 constant variables applied are operating pressure which is kept at 21 bar and gas-to-oil ratio of 250 L/L and 2 independent variables applied are temperature at 300oC; 310 oC; 330 oC; 350 oC; 370 oC; 390 oC and liquid hourly space velocity (LHSV) of 0,5 hr-1; 1 hr-1; 1,5 hr-1; 2,75 hr -1; 3,75 hr -1. Based on the conducted experiment, some results were obtained. In temperature below 350oC, yield of saturated compound in HDA reaction increased as the temperature rose. In temperature above 350 oC, yield of saturated compound in HDA reaction decreased as the temperature rose. Yield of saturated compound in HDA reaction decreased as LHSV rose. The conversion of sulphuric compound during HDS reaction increased as the temperature rose. The conversion of sulphuric compound during HDS reaction decreased as the LHSV rose. The optimum operating conditions are temperature of 350oC and LHSV of 0,5 hr-1 for HDA reaction, and temperature of 390oC and LHSV of 0,5 hr-1 for HDS reaction.
