Abstract

The National Energy Policy to develop the use of renewable energy has opened up opportunities for industry to develop the use of biomass. A study on the use of palm shells as a substitute for industrial diesel in a thermal oil heating system at a natural rubber resin factory in North Sumatra has been carried out. All information and data on the operation of TOH were obtained through secondary data collection and direct discussions in the field. The secondary data obtained include the type and specification of the heater, the characteristics of the thermal oil (type, flow rate, temperature inlet and outlet of the heater), fuel consumption/hour and the characteristics of palm shells. From the study conducted, it can be concluded that during the process of heating thermal oil which takes place gradually in the TOH system using industrial diesel, it has a heat capacity of 1,500,000 kcal/hour, but the maximum heat that is useful for heating thermal oil is 694,396 kcal/hour with maximum thermal efficiency is 80.69%. Estimated consumption of palm kernel shells required to heat thermal oil on the assumption of 70% thermal efficiency as a substitute for energy supplied by industrial diesel is 237 kg/hour. The savings from this fuel replacement is estimated Rp.3.286.800.000/year.

Abstract

Acid Value and Saponification Value are used as parameters to measure Fatty Acid quality in Splitting Triglycerides from vegetable oils by hydrolysis process, Crude Palm Kernel Oil separation process to form Crude Fatty Acid and Glycerin in the Oleochemical Industry and is a reference for achieving the capability separation process in the Splitting Column by Splitting Degree of Hydrolysis method. From the results our study, we found that the tenth data from our test parameters observations are out of control but within specified range. Quality test parameters set for acid value and saponification value are in the range of 250 – 254 and 252–255 mg.KOH.g-1. The results of quality control at 252.411 and 253.55 mg.KOH.g-1 by a range 0.78 and 0.651, respectively for each parameter. The average of two parameters for hydrolysis conversion is 99.54 %, This result meets industry standards to produce good quality Crude Fatty Acid. The process capability value for Crude fatty acid production for parameter acid and saponification value are 1.45 and 1.30 respectively. Both values indicate that the hydrolysis separation process is running very well. The quality control Splitting Degree of Hydrolysis method using a control chart approach and process continuous capability for the resulting product can be used as a consideration in determining the quality of fatty acids and predicting fatty acid composition.
