ABSTRACT
The increasing number of motorized vehicles is not matched by proper waste emission
processing, which has a negative impact on the environment in the form of air pollution. This
is a result of the incomplete combustion process so that the number of pollutants produced is
increasing. One way to reduce the occurrence of incomplete combustion is by increasing the
value of the octane number in motor vehicle fuel oil with additives that can increase the
octane number such as methyl tert butyl ether (MTBE). MTBE production process is carried
out by reacting the feed in the form of methanol with isobutene and the obtained production
capacity is 180,000 tons / year. In the design of the distillation tower for the separation of
methanol and Tertiary Butyl alcohol (TBA), the feed temperature, tower top and bottom of
the tower were 333 K, 298 K and 328 K. The feed, distillate and bottom flow rates were
11,858 kg / hour, 10,644 kg, respectively. / hour and 1,214 kg / hour. The tower diameter is
2.27 m, with a spacing tray of 0.45 m, and the number of trays (without a reboiler) is 28. The
type of flow that occurs inside the tower is a double pass with a total tower height of 13.77 m.
The main equipment required is one reactor (fixed multitubular), one mixer (paddle), four for
the distillation unit (sieve tray), three Heat Exchangers (one double pipe and two shell and
tube), two heaters (shell and tube). , two coolers (double pipe), three centrifugal pumps, and
five storage tanks (methanol, isobutene, MTBE, Butane and Water). The amount of Fixed
Capital Investment (FCI) is $ 39,009,534. The amount of Direct Cost (DC) is $ 17,571,862
and Indirect Cost (IC) is $ 21,437,671. The Working Capital Investment (WCI) fee is $
6,884,035 and the Total Capital Investment (TCI) fee is $ 45,893,569. The value of the Break
Even Point (BEP) is 50%. The amount of Return On Investment (ROI) is 52%, Pay Out Time
(POT) is 1.5 years, Shut Down Point (SDP) is 0.1% and the Internal Rate of Return (IRR) is
22.76%. The most sensitive factors that can affect the feasibility of this project are the selling
price of the product and the volume of production. So that based on the analysis that has
been done, it can be concluded that the factory is feasible to build.
Keywords: Methyl tert butyl ether, tertiary butyl alcohol, total capital investment
