Abstract


This study tested the effect of electromagnetic field on density and viscosity of vacuum residue from PT. PERTAMINA Refinery Unit III Plaju. The study was conducted using a batch reactor equipped with electromagnetic. The fixed variable in this study is the vacuum residue mass and cracking time, while the variables which are varied are reaction temperature and electromagnetic field. The study was conducted to see the effect of temperatures ranging from 100, 200, 300 and 400oC, and the use of electromagnets with electric currents of 0A, 5A, 10A, 15A and 20A on the density and viscosity of vacuum residue. The experiment compared the effect of the process with electromagnetic field and without electromagnetic field on the density and viscosity of vacuum residue. The results showed that the lowest density (0.874 g/cm3) and viscosity (0.481 cP) were obtained by using 20A electric current electromagnetic field at a temperature of 400oC.

Penelitian ini dilakukan untuk menguji pengaruh medan elektomagnetik terhadap densitas dan viskositas vakum residu petroleum dari PT. PERTAMINA Unit Pengolahan III Plaju. Pengujian dilakukan dalam reaktor-batch yang dilengkapi dengan elektromagnetik. Variabel tetap dalam penelitian ini adalah massa vakum residu dan waktu cracking, sedangkan variabel yang divariasi adalah suhu cracking dan kuat arus listrik elektromagnetik. Studi dilakukan untuk melihat pengaruh suhu mulai dari 100, 200, 300, dan 400oC, serta penggunaan elektromagnet dengan arus listrik sebesar 0A, 5A, 10A, 15A dan 20A terhadap perubahan densitas dan viskositas dari vakum residu. Eksperimen yang dilakukan membandingkan pengaruh proses dengan medan elektromagnetik dan tanpa medan elektromagnet terhadap densitas dan viskositas vacuum residue. Hasil penelitian menunjukkan bahwa nilai densitas dan viskositas vakum residu terendah diperoleh pada penggunaan medan elektromagnetik dengan arus listrik 20A pada suhu 400oC yaitu pada nilai denitas sebesar 0,874 g/cm3 dan nilai viskositas sebesar 0,481 cP.
