Neraca Massa dan Pengembangan Proses Mandiri Energi Pada Pabrik CPO

Abstract

Palm oil mill consumes large amounts of energy so that the limited supply of fossil fuels in the future become a production constraint. The purpose of this study was to calculate the rational energy requirements of CPO production and assess the adequacy of energy through the utilization by-products of byproducts. Mass balance model was developed to describe the need and the sufficiency of energy. The results of the model calculations based on the rational performance, palm oil mill with capacity of 60 tons fresh fruit bunches/hour produce crude palm oil at 26.80% yield. This production coupled with biomass by-products include empty bunches, fiber, shells, and liquid waste 1,4265.3 kg, 4,612.9 kg, 1,958.7 kg and 21,057 kg respectively. These by-product potentially consist of energy as much as 65,006,768 kcal. This energy can be used to meet the energy needs of 1,020 kWh of electrical plant and steam 30 tons with an excess energy of 1,021.78 kWh. Palm oil mills can be a surplus energy production system. Therefore it is recommended that palm oil mills should be restricted in using fossil energy and electricity from public network.
