| dc.description.abstract | Preliminary design of azodicarbonamide plant from biurea and chlorine
with the capacity of 50.000 ton/year is planned to be built in Cilegon, Banten.
This chemical plant will be operatedfor 330 day/year or 24 hours a day with 150
employees.
Raw material needed is biurea of 59834 ton/year and chlorine of 39535
ton/year. The production process will be operated at temperature of 45 °C, and
pressure about 1 atm using bubble reactor with 85 % convesion of
azodicarbonamide. The utiliy consists of 43651 ton/year of cooling water, 13368
ton/year of housing water, while the power of electricity of about 273.82 kWh
provided by PLN. This chemical plant also uses generator set as electrical
reserve.
An economic analysis shows that this chemicalplant needs byfixed capital
of about $ 11.961.194,04 i Rp 185.724.114.463, working capital of about Rp
161.263.818.925 + $ 17.433.926,37. The profit before tax is Rp
117.660.201.731,34 peryear while the profit after tax is Rp. 100.011.171.471,98
per year. Percentage of return on investment (ROT) before tax is 0,83 %, while
that ofafter tax is 0,95 %. Pay out time (POT) after tax is 2.70 years while that of
after tax is 4.3 years. The value of break evek point (BEP) ofabout 43,10% and
shut down point (SDP) of about 25,82 %. Based on the economic analysis, It is
concluded that plant design ofazodicarbonamide with capacity 50,000 ton/years
feasible to be built. | en_US |
