Pengaruh Variasi Kondisi Operasi pada Kolom Distilasi Ekstraktif terhadap Sifat Fisis Pelarut Hidrokarbon Terdearomatisasi

Solvent is one of the important components in chemical processes. The type solvent that often used paint and coating industry a hydrocarbon-based which consists diverse complex mixture liquids contains aliphatic, alicyclic aromatic (C5-C8) elements. Aromatic hydrocarbons are environmental pollutants known to be toxic, carcinogenic mutagenic, so with an content less than 1% needed. An appropriate separation method for separating nonaromatic having close boiling points extractive distillation sulfolane entrainer. In this study, system entrainer was run using process simulation software Aspen Plus aim understanding effect amount sulfolane, feed stage number stages on physical properties solvents. This focused variation ratio sulfolane: crude (7:1, 7.5:1, 8:1, 8.5:1), (10th 35th stage) (70, 75, 80). It found did not affect density flash point solvent. increase will decrease density. Significant decreament also can when increased. However, current dearomatized commercial product namely SBP 65/70 from oil gas companies.
