Diethyl malonate plant from monochloracetic acid design with a production capacity of 12,000 tons / year. Diethyl malonate is really needed as raw material in many industry, especially in medical, vitamin and pharmacy industry. Manufacturing process with the following steps: dissolution of raw materials, salt formation, sianifikasi reaction, the esterification reaction and product separation and purification processes in the form of decantation process and distillation process. The plant will be established in Gresik, East Java with a land area of 4 hectares. To product diethyl malonate with the capacity 12,000 tons/ year, the materials needed are monochloracetic acid as much as 8723.4 tons/ year, NaOH 40 % as much as 9229.92 tons/ year, NaCN as much as 4526.52 tons/ year, ethanol 95 % as much as 8940.48 tons/year, H2SO4 98 % as much as 8310.248 tons/year and benzene as much as 217.08 tons/year. Beside that, to support this process, the utility takes water as much as 80615.262 M 3 / year, 868.81 kVA electrical needs, and steams 351.301 kgs / hour. Fixed capital required amounted to US$ 60,894,445 + Rp. 126,574,858,327 and working capital US$ 13,686,946 + Rp 19,942,836,010. Profit before tax is Rp. 10,469,379. And profit after tax is Rp. 5,234,689. From the results of calculations, the Return on Investment (ROI) before taxes 31,77 % and 15,88 % after tax. Pay Out Time (POT) before taxes 2,4 years, 3,86 years after tax. Break Even Point 40,70%, Shut Down Point 16,4% and Discounted Cash Flow Rate Of Return 31,38%. From the results of the feasibility study plants through economic evaluations have been done on plant diethyl malonate from monochloracetic acid with a production capacity of 12,000 tons / year can be concluded that the plant deserves to be studied further.
