Turpentine is liquid phase from the sap of Pinus merkusii tree is the material to obtain components such as ?-pinene, ?-pinene, ?-carene, and limonene. Perhutani Pine Chemical Industry (PPCI) is a factory that focuses on obtaining derivative components of turpentine. However, until recently, PPCI only succeeded in separating the ?-pinene component from turpentine as the top product from distillation, while the bottom product containing the remaining components was immediately sold by PPCI under the name of pine oil. Distillation at atmospheric pressure could degrade some of turpentine components. If these turpentine components can be separated, it will increase its value than by selling it as pine oil. This study aims to obtain the optimum operating conditions in turpentine component separation process from pine oil. The experimental method used consisted of three stages. The first stage is the analysis of components of raw materials ie turpentine. The second stage is the fractionation of turpentine by a partitioned vacuum distillation process to obtain distillate. The third stage is the analysis stage of distillate by Gas Chromatography with FID. The experiment was conducted by varying the operating pressure of the vacuum distillation process which is at 0.2 atm; 0.45 atm and 1 atm. Experiment showed that thermal degradation didn’t occur at 0,45 atm and 0,2 atm operating pressure. Experiment result is in match with simulation result with column efficiency of 45%. Better result could be achieved by increasing the stage to 25 stage from 10 stage previously used and acquiring analyst grade composition (>99%). Distillation at 0,2 atm operating pressure proved to be the best assessed by its profitability and energy consumption.
