【 摘 要 】

Blending simulation is an important tool for blending process in oil and gas companies, for example PT. Pertamina (PERSERO) RU IV Cilacap. Crude oil is processed to become a product that can be used by the public such as Premium, Pertamax, and Pertamax Plus. In this case study, simulation blending is used to determine the optimal composition of Premium and Solar blending. Before the blending process, the Refinery Planning and Optimation division simulates the blending process by calculating so that the mixing process is in accordance with the desired quality. The results of the research showed that there was a decrease in performance units so that reformate cannot be fully entered as a Premium component and requires HOMC for blending, so that the margin in USD/barrel units decreases by 0.82 USD/barrel. In the initial condition of Solar, the margin obtained was 24846.04 thousand USD or 8.04 USD/barrel. From the optimization results, it can be seen that to obtain sulfur content of 0.3% wt, the amount of HGO was 20286.19 TON or 676.21 TPSD and the VGO amount was 11050.01 TON or 368.33 TPSD and the maximum margin that can be obtained was 28381.34 thousand USD or 9.18 USD/barrel. The margin condition in USD/barrel after the optimization of Solar sulfur content increased by 1.14 USD/barrel. At optimum conditions, the amount of Solar produced increases because it gets an additional from Solar components with high sulfur content VGO and HGO.
