Abstract

Formic acid (HCOOH) or methanoic acid is the first derivative of carboxylc acids. Formic acid is widely used in the textile, pharmaceutical, cosmetic, rubber, and ather industries. To meet domestic and foreign demand for formic acid, a formic acid plant is designed from the hydrolysis of methyl format with a capacity of 20.000 tons/year. The factory is planned to be established in Gresik, East Java and is scheduled to start operating in 2030. The formic acid production process is carried out by hydrolysis of methyl format in a CSTR reactor. The reaction occurred under endothermic conditions at a temperature of 90ºC and a pressure of 5 atm. To support the production process, supporting units or utilities are needed, such as a water supply and processing unit, a steam supply unit, a compressed airsupply unit, an electric power supply unit, a fuel supply unit, a laboratory unit, and a waste processing unit. The formic acid factory design is evaluated and assessed regarding the investment plan. Based on feasibility analysis calculations, the Percent Profit on Sales before tax was 29.44% and after tax was 22.08%. The Percent Return on Investment before tax was 33.02% and after tax was 24.77%. The Pay Out Time was estimated at 3.9 years. Furthermore, the Break-Even Point was determined to be 33.41% of the production capacity, with a trial Internal Rate of Return (IRR) of 15.89%. Meanwhile, the plant’s Shut Down Point was calculated to be 19.94% of the production capacity.
