Prarancangan Pabrik Pembuatan Dietanolamida dari Metil Ester Sawit dan Dietanolamina dengan Proses Amidasi dengan Kapasitas Produksi 30.000 Ton/Tahun

Abstract

The prelimenary design of diethanolamide plant from palm methyl ester and diethanolamine by amidation process with production capacity of 3,000 tons/year and operates for 330 days a year. The main process in this plant design consists of two stages, namely the formation stage of diethanolamide and the purification stage. In the formation stage of diethanolamide, a continuous stirred tank reactor operating at 120°C pressure 0,5 atm for 5 hours is used which requires palm methyl ester of 3,030.303 kg/hour and diethanolamine of 1,329.167 kg/hour with sodium methoxide catalyst of 85.984 kg/hour. In the amidation process, a reaction conversion of 99.06% was obtained. Then in the purification stage, several stages occur, namely the acetylation stage, the evaporation stage, and the filtaration stage. The resulting diethanolamide has a purity of 92.66%. The plant is located in Kawasan Industri Medan 2, Medan Belawan, Sumatera Utara with an area of 13.103,2 m2. The plant's water needs are supplied from the Seruai River. The plant's electricity needs are fulfilled by using a generator with capacity of 300 kW. The planned form of business entity is a Limited Liability Company (LLC). The planned organizational form is a line and staff with the required total workers of 158 people. The results of the economic aspect analysis obtained are as follows: • Capital Investment (CI) : Rp 653.571.026.330 • Total Cost (TC) : Rp 926.147.884.489 • Total Sales (TS) : Rp 1.193.839.168.186 • Profit Margin (PM) : 21,30% • Break Even Point (BEP) : 43,04% • Return on Investment (ROI) : 27,25% • Pay Out Time (POT) : 3 tahun 8 bulan • Return on Network (RON) : 45,41% • Internal Rate of Return (IRR) : 17,67%
