Abstract

Palm oil mill may be operated in batch, continuous and semi-continuous mode. Sterilization process determines the operation mode of palm oil mill. This study was conducted to evaluate the comparison of process design among continuous, semi continuous and batch process ofpalm oil miiling using computer aided process simulation, SuperPro Designer. Based on literatures, Block Flow Diagram (BFD) and mass balance of each procedures were developed. Then, input data including processing data, economic evaluation parameters and others were identified. 3 separate flowsheets which are batc\ continuous and semi-continuous were then developed in SuperPro Designer. Generated reports through SuperPro Designer were next used as the sources of comparison and the feasibility between the milling t51pes was deterrnined. Through economic evaluation report, several key parameters were amlyzed such as total capital investment, annual operating cost and revenues. Continuous milling recorded the highest NPV which then followed by semi-continuous and batch milling. Higher equipment cost in batch milling highly affect total capital investrnent cost. Moreover, it was found that semi-continuous milling requires much higher labor cost with annual cost of RM 1,381,000 compared to RM 791,000 for batch milling. The lowest net unit production cost is RM 2.76lkg from continuous milling and it is still much higher than the reported cost which is RM l.4Vkg. Throughput analysis which determine debottlenecking of equipment and operating daVs were also analyzed. Therefore, based on this study it can be concluded that continuous palm oil milling is the most feasible and economical milling type.
