Abstract

Boilers function to produce hot water or hot steam from combustion products to be converted as energy. Steam is used to drive turbines to produce electrical energy, apart from that steam is also used for heating. The boiler fuel uses biomass in the form of tree bark, namely acacia mangium. The aim of this study is to find out whether the process running in the Power boiler is good or not, it can be seen from its efficiency, so that the energy balance calculation is carried out on the Power boiler itself. Therefore, a study is needed to determine the energy balance of the unit. From the heat balance calculation, the heat data for producing steam was 1924,927,054 kcal, the latent heat of vaporization was 5732,620,038 kcal and the feed water heat was 11156296.65 kcal. So from the calculations obtained we can find out the energy balance in the boiler and the resulting Supply Steam Consumption

Abstract

Liquified Natural Gas (LNG) is natural gas that is used as a safe, clean and efficient energy source. LNG itself is liquefied and has been processed to remove impurities and heavy fraction hydrocarbons which are then condensed into liquid at atmospheric pressure with a temperature of -160 ºC. In Indonesia, LNG has good prospects for development, both in terms of raw material potential and its market. So, it is very appropriate if an LNG plant is established in Indonesia with the aim of meeting domestic LNG needs and opening up new jobs to reduce unemployment in Indonesia. LNG is made through several stages of the process, namely the Absorption, Dehydration, Fractionation and Liquefaction processes. The factory will be established in Muara Enim, Lahan Regency, South Sumatra Province. From economic calculations, it is obtained that the return on investment is 3.08 years after the factory is established. The rate of return on capital is 38.1%, and the BEP is 37.6%. Based on the economic analysis, the LNG plant from Natural Gas is feasible to be established.
