| dc.description.abstract | This coal tar refining plant to produce toluene has a production capacity of
14,500 tons/year and operates for 330 days a year. The main process in this plant
design consists of separating components contained in coal tar such as benzene,
toluene, pyridine, m-xylen, 4-methylpyridine, phenol, and cresol by entrainer-assisted
pressure-swing distillation (EA-PSD) method to separate toluene and pyridine. The
amount of coal tar required to achieve the annual production capacity is 6.659,
135kg/hour.
The specific task completed was the detailed engineering design of the distillation
tower to purify toluene. The designed distillation tower has the following
specifications:
• Number of tray : 17 tray
• Inlet feed tray : 9th tray from bottom
• Height of Distillation Tower : 8,952 m
• Diameter of Distillation Tower : 0,864 m
• Distillation column shell material : Carbon steel SA-283 grade C
• Thickness of distillation column shell : 3/16 in
• Thickness of distillation column head : 3/16 in
• Distillation column tray material : Stainless steel
The coal tar refining plant to produce toluene is planned to be established in
Blora Regency, Central Java Province, with a total plant area of 17,550 m2. The water
requirement for this plant is supplied from Bengawan Solo River as much as 4,700.553
kg/hour. The planned form of company organization is a Limited Liability Company
(PT) with a line and staff organizational structure, and a total of 190 employees.
The results of the economic analysis on this plant proposal are as follows:
• Capital Investment (CI) = Rp 529.456.039.793
• Total Cost (TC) = Rp 238.713.484.696
• Profit Margin (PM) = 47,596 %
• Break Even Point (BEP) = 43,927 %
• Return on Investment (ROI) = 30,114 %
• Return On Network (RON) = 50,190 %
• Pay Out Time (POT) = 3 tahun 4 bulan
Internal Rate of Return (IRR) = 26,618%
Based on the results of the economic analysis, it can be concluded that the coal
tar refining plant to produce toluene is feasible to establish. | en_US |
