| dc.description.abstract | Pre design of Liquified Methane Gas (LMG) with 1000.000 ton/year
capacities is made to fullfill the energy alternative requirment besides the methane
needed in Indonesia. This factory will reduce the dependence to foreign industries
besides it can be exported to the other countries that will increase our foreign
exchanger. It will be built in Cikarang, Bekasi.
Raw material, which is called manure, are from cattle waste which can be
obtained from some catties around the factory. The reaction of the manure to be
biogas is a fermentation reaction process which the operation is run in the
isothermal condition, 38 °C and 1 atm. The raw material needed is 163126.83
kg/hour and water (H2O) are 28084.96 kg/hour. The convertion of the reaction is
85% and the equipments are fermenter reactor, absorber, stripper, dan Knock Out
Drum.
The process of production is supported by utilities unit that consists of
water supply process 489996.2858 kg/hour, steam supply process 14932.1910
kg/hour, electricity suppy process 623.1790 kW and fuel supply process
1374.5494 kg/hour. Water used in water supply process is taken from river near
the factory. This factory is planned to be built in the 150.000 m2ofarea. The man
power for this factory consists of 216 employees.
The result of the economic analysis shows that the fixed capital investment
(FCI) needed to build this LMG factory is Rp 1.650.940.922.931,95, the work
cost (WC) is Rp 330.446.137.748,50, the benefit before tax per year is Rp
511.676.805.731,34 and the benefit after tax per year is Rp 255.838.402.865,67.
While percent return on investment (ROI) before and after tax are 30.993 % and
15.4965 %, respectively. Pay out time (POT) before tax is 2.4394 years and after
tax is 3.9221 years, break event point (BEP) is 41.2003 %, shut downpoint (SDP)
is 16.5369 %, and Discounted Cash Flow (DCF) 30,34 %. Finally, based on The
result of economic analisys it can be concluded that the factory of Liquified
Methane gas is very interesting to be built. | en_US |
