| Summary: | Gasoline and Liquefied Petroleum Gas are energy resource that
commonly used in daily life and industry. Most gasoline and LPG are made
from fractional distillation of crude oil-which its reserves are reduced every
day. These products contain high sulfur, poor octane number, and need extra
treatment for removing the heavy metals. The new technology called MTG
(Methanol to Gasoline) Process with gamma alumina and ZSM-5 catalyst can
be the answer of these issues.
C1-C10 hydrocarbon and aromatic called durene are formed from
methanol two series of adiabatic fixed bed reactors. First reactor convert
methanol to dimethyl ether (DME) and the second reactor convert the DME to
C1-C10 hydrocarbon and the aromatic. Gamma alumina catalyst is used in the
first reactor, the second used ZSM-5 catalyst. These series of reaction occurs
in high temperature, the temperature out of the second reactor is about 1100K
with 15,6 atm pressure.
This MTG plant is designed for annual capacity of 981.000 ton/year
and operates continuously for 330 days. This plant requires raw material
methanol in amount of 3.490.000 ton/year. This futuristic plant is planned to
be built in Bontang, Kalimatan Timur. The land required for this plant is
148.200 m2. The employers needed to run this plant are 216 persons.
From economic analysis it is obtained that, this plant requires a fixed
capital investment of US$ 153.094.754,28 and Rp 459.078.348.680,99. For
working capital as much as US $ 188.397.828,57 and Rp
1.587.807.219.096,21. This plant will earn a before taxes profit Rp
750.943.524.898,07 with taxes rate of 50%, it will earn an after taxes profit of
Rp 375.471.762.449,04. A feasible study concludes an Return on Investment
(ROI) before taxes of 35,0% & and ROI after taxes 17,5%. Pay Out Times
(POT) before taxes is 2,27 years and POT after taxes is 3,77 years. Discounted
Cash Flow is 13,40%. Break Even Point is 57,11 % and Shut Down Point is
40,50 %. Based on this economic study, this gasoline from methanol plant is
economically feasible. |
