Pra Perancangan Pabrik Acrylonitrile dari Ethylene Cyanohidrine dengan Kapasitas 60.000 Ton/Tahun
Abstract
Acrylonitrile (ACRY) is substance for making Synthetic fiber. Rubber,
Plastic which used for making home tools, office equipments, etc. Acryonitrile
Monomer factory purpose to full fill domestic required even for export. Vinyl
Chloride Monomer factory will build in South Sumctra industry distric at Mariana
with 60000 ton/year product capacity and has 166 employes.
Basic material for ACRY product is Ethylene Cyanohidrine (EC).. Ethylene
Cyanohidrine mechanism reaction need dehidrasi process in reactor fixed bed non
adiabatic with AL203 solid catalyst. The reaction runs on 250 C with 2 atm
pressure. It has about 99% conversion. And than reaction product ACRY process
craking in distillations minaret to make ACRY, The reaction runs on 87.54 C with
1.1 atm pressure. It has about 80% conversion. The product appeared after reboiler
process in distillation minaret than condensed. And than reaction product ACRY
process craking in Stripper minaret to make ACRY, The reaction runs on 104,4°C
with 1.2 atm. It's saved as liquid essence.
The factory need 9,1755 kw of electricity which supply by PLN; and
41,131,4623 kj/k of fuel.
The factory fixed capital is Rp 294,510,772,013.2, it's from bank loan and
capital investment and the factory needs Rp 199,479,508,008 working capital. It
hasRp 82,054,146,389 profit in a year before tax and Rp 41,027,073,195 in a year
after tax. It's counted that return on investment (ROI)is 28% before tax and 14% ater
tax; pay out time (POT) is 2.91 year before tax and 4.91 after tax; break even
point(BEP) 55.74%; shut down point(SDP) 43.32%; and discounted cash flow rate of
return (DCFR)30%. Based on the economic analysis, It is concluded that plant design
of Vinyl Chloride Monomer with capacity 60000 ton/years visible to be built.
