ABSTRAK
Ethylene is one of the most important petrochemical substances and it’s uses as raw material for
various products. The last products made with ethylene include food packaging, toys, food
containers, bottles, pipes, antifreeze, carpets, insulation, household appliances, etc. Chemicals
made from ethylene to produce end products such as polyethylene, ethylene dichloride, ethylene
oxide, ethylbenzene, and vinyl acetate. The ethylene production process is carried out by feeding
naphtha into the thermal cracking reactor and a production capacity of 155,000 tons / year is
obtained. In the thermal cracking reactor design to break the hydrocarbon chain of naphtha, the
feed temperature is 650 oC with a feed flow rate of 70,620.95 kg/hour dimensions of the thermal
cracking reactor is 20 ft long, 40 ft wide and 100 ft high including chimney 100 ft. Heat (Q)
required is 88,314,298.72 Btu / hour. The amount of Fixed Capital Investment (FCI) is $
45,879,155.2. The Cost of Working Capital Investment (WCI) is $ 8,096,321,505 and the Total
Capital Investment (TCI) cost is $ 53,975,476.7. The Cumulative Cash Ratio (CCR) values for
nondiscounted and discounted 10% are 2.2 and 1.21, respectively. The amount of rate of return
on investment (ROROI) is 22.7%, Pay Out Time (POT) for non-discounted profitability and
discounted 10% profitability are 3.46 years and 6.84 years respectively, the value of the
Discounted cash flow rate of return (DCFROR) is 13.55% and every 2% increase in sales and
investment (FCI) there is a change in NPV of $ 129,886,499.71. Therefore based on the analysis
that has been done it can be concluded that the factory is feasible to build.
Keywords: Ethylene, Naphta, Thermal Cracking, total capital investment
