Abstract
Acetone cyanohydrin ((CH3)2COHCN) is produced from acetone ((CH3)2CO) and hydrocyanic acid (HCN) with base catalyst NaOH in a continuous stirred-tank reactor (CSTR). The operating pressure in the reactor is 2 atm with the reaction temperature at 35 ° C. The formation reaction of acetone cyanohydrin is exothermic reaction so that reactors are equipped by cooling coil. The factory is designed with 20,000 tons/year capacity and it is planned to operate continuously for 330 days/year. The raw materials to produce acetone cyanohydrin 99,5% required are acetone 99.5% as much as 13.720,88 tons/year, HCN 99% as much as 6.389,64 tons/year and 99% NaOH as a catalyst as much as 199,06 tons/year, sulfuric acid 98% as much as 246,53 tons/year. The factory is planned to be built in the industrial area Karawang, West Java in 2020, with requires land area as 20.381 m2, and requires a workforce of 218 employees. Fixed capital needed is Rp 534.921.806.654,41 and working capital of Rp Rp 94.397.965.880,19. The results of an economic evaluation showed a profit after taxes is Rp 220.438.707.347,05. Return on Investment (ROI) after tax of 35%. Pay Out Time (POT) 1,94 years for after tax. Discounted Cash Flow Rate of Return (DCFRR) is 31,9%, Break Even Point (BEP) at 41% and Shut Down Point (SDP) at 27% of plant capacity. Based on the results of the economic evaluation, the plant is deserved to be studied further.
