| dc.description.abstract | Preliminary design ofPhthalic Anhydridefor 45000 ton/year ofcapacities
O-xylene and Air (oxygen) oxidation ofPthalic Anhydride with purity 99%. This
plant is planned to be built in Tangerang, Banten. Itcovers 35000m ofland and
needs 146 employees. It works continuallyfor 24 hours /dayand330 day/year.
This process is using Von Heyden Method. The process of reaction is
exothermic using V205 as catalyst toproduce Phthalic Anhydride in FixedBed
Multitube Reactor at 35(fCand 1,4Atm. Process unit requires 5390.10 kg/hour
ofO-xylene and96074.01 kg/hour ofair, whereas utility unit needs 133223.9788
kg/hour water for cooling, 1152,576 kg/hour water for domestic, 97589,69147
kg/hour ofsteam, 194,403 KWelectricity, 476,394 kg/hour offuel oil,
Economic evaluation shows that Fixed Capital ofRp 165.474.829.874,14,
profit before taxes Rp. 75.563.373.262,23 profit after taxes
Rp.52.894.361.283,56,.From feasibility studies result Break Even Point (BEP) of
45,33% (BEP requisite inIndonesia 40-60%), Shut Down Point (SDP) of20,53%
andDiscounted Cash FlowRate ofReturn (DCFR) of34%. Meanwhile Return on
Investment Before Taxes (ROIb) of 26% (ROI b requiste for high riskplant >
44%) andReturn onInvestment After Taxes (ROI a) of18%. Pay Out Time Before
Taxes (POTb) 2,7 yearsa (POT b requiresfor high risk plant< 2 years)andPay
Out Time After Taxes (POT a) 3,472% in a row. Based on this economic
evaluaton it can be concluded that Pthalic Anhydride Plant of45000 ton/year is
economicallyfeasibility. | en_US |
