Abstract

Pengujian kandungan gum pada nafta sebelum dan setelah penambahan antipolymerant telah dilakukan. Pengujian tersebut bertujuan untuk mengetahui potensi 2,2,6,6-Tetramethylpiperidine-1-Oxyl (TEMPO) dalam menghambat polimerisasi olefin dan pengaruhnya terhadap karakteristik nafta. Nafta sebelum dan setelah penambahan antipolymerant diuji kandungan gumnya dengan metode jet evaporation yang mengacu pada ASTM D381. Hasil uji kandungan gum menunjukkan peningkatan kadar gum setelah penambahan TEMPO dengan persen inhibisi -23,8%. Sedangkan nilai warna nafta dan nafta + TEMPO berturut-turut yaitu 24,6 dan 16,9. Densitas nafta dan nafta + TEMPO yaitu 0,7254 dan 0,7257. Testing of gum content in naphtha before and after addition of antipolymerant has been studied. The test aims to investigate the potential of 2,2,6,6- Tetramethylpiperidine-1-Oxyl (TEMPO) in inhibiting olefin polymerization and its effect on naphtha characteristics. Naphtha before and after addition of antipolymerant tested the gum content by jet evaporation method which refers to ASTM D381. The results of the gum content test showed an increase in gum content after TEMPO addition with percent inhibition is -23,8%. While the color of naphtha and naphtha + TEMPO is 24,6 and 16,9. The density of naphtha and naphtha + TEMPO is 0,7254 and 0,7257. Based on these data, it can be concluded that TEMPO has not potential as alternative antipolymerant for naphtha.
