Daftar Isi:
- 1.4 Dicyano-2-butene solution is prepared by reacting 1.4 Dichloro-2-butene and Sodium Cyanide using Sodium Cuprouscyanide catalyst in a stirred tank reactor equipped with the cooling coil. The reaction is conducted at a temperature of 80 °C, isothermal, and pressure of 4.4 atm. The heat generated from the reaction is absorbed by the cooling water in the cooling coil. The final conversion of dichlorobutene in the reactor reaches 90%. To produce 100.000 tonnes/year dicyanobutene (99.8%), the dichlorobutene (99.75%) needed is 115.263 tonnes/year, 68.496 tonnes/year of NaCN solution (30%), 15.304 tons/year NaCu(CN)2 catalyst solution, and 2.320 tonnes/year HCN solution (9%). The needs for utilities including, water as much as 303.278 tonnes/year,6.107 m3 residual fuel oil number 6 (diesel oil for industrial), and electrical power of 786,52 kVA. The plant is planned to be established at Cilacap, Central Java, Indonesia, near the harbor. The land area of 100.000 m2 is required. The plant operate continuously for 24 hours/day, 330 days/year, with a total labor of 122 people. The time for annual turn around takes 35 days, including start-up and shut-down. Fixed capital required is Rp. 201.645.030.649,46 + 53.463.717,03 $ with the value of 1$ is Rp. 9.595,00. The working capital required is Rp. 1,224,261,853,437.29 per year. The profit before tax is Rp. 232,809,144,469.32 per year and the profit after tax is Rp. 116,404,572,234.66 per year, Pay Out Time (POT) before taxes is 2.27 years, Pay Out Time (POT) after the tax is 3.07 years, Break Even Point (BEP) is 52.43%, and Shut Down Point (SDP) is 33.60%. From the analysis above, this plant is economically quite interesting and worth to be considered further.
