Abstract
The Barium Carbonate Plant from Barium Sulfate and Sodium Carbonate, with a production capacity of 25,000 tons/year, is planned to be established in the Java Integrated Industrial and Port Estate (JIIPE), Manyar, Gresik, East Java, in 2030. The barium carbonate plant is designed to operate continuously for 24 hours per day with 330 operating days per year and a total of 272 employees. The main raw materials used are barium sulfate (BaSO₄) and sodium carbonate (Na₂CO₃), which are supplied by PT Gochem Globalindo, Surabaya. The main product is barium carbonate (BaCO₃), which can be utilized in various industrial sectors, including the ceramic, glass, brick, and construction materials industries. In this plant, barium sulfate (BaSO₄) is reacted with sodium carbonate (Na₂CO₃) in the form of a slurry. The production process begins with the mixing of the raw materials and slurry formation, followed by feeding the slurry into the reactor. After the reaction takes place, the resulting slurry undergoes rapid cooling in a quench tower to approximately 40°C to help maintain the barium carbonate product and reduce the tendency of the reverse reaction. Subsequently, the slurry undergoes solid-liquid separation, thickening, and drying using a rotary dryer to obtain the barium carbonate product. The specifications of the proposed barium carbonate plant can be summarized as follows: a. Production Capacity : 25,000 tons/year b. Type of Company : Limited Liability Company (PT) c. Organizational Structure : Line and Staff d. Plant Location : JIIPE, Manyar, Gresik, East Java e. Number of Employees : 192 people f. Operating System : Continuous g. Operating Time : 330 days/year; 24 hours/day h. Raw Materials 1. Barium Sulfate (BaSO₄) : 3,728.1404 kg/hour 2. Sodium Carbonate (Na₂CO₃) : 3,392.1277 kg/hour i. Product 1. Barium Carbonate (BaCO₃) : 3,156.2360 kg/hour j. Reaction Conditions 1. Temperature : 220°C 2. Pressure : 9 atm 3. Residence Time : 15 minutes k. Reaction Yield : 85% l. Utility Requirements 1. Electricity Requirement : 6,232 kWh 2. Water Requirement : 327.4624 m³/hour 3. Fuel Requirement : 3,263,605.72 L/year m. Plant Building Area : 3,493.1493 m² n. Fixed Capital Investment : IDR 148,497,497,197 o. Working Capital Investment : IDR 51,668,920,856 p. Total Capital Investment : IDR 200,166,418,053 q. Raw Material Cost (per year) : IDR 27,796,912,213 r. Utility Cost (per year) : IDR 57,081,695,595 s. Production Cost : IDR 206,675,683,424 t. Sales Revenue : IDR 269,146,885,330 u. Bank Loan Interest Rate : 8% v. Rate on Investment (before tax) : 25.86% w. Rate on Investment (after tax) : 19.39% x. Payback Period : 3 years 10 months y. Internal Rate of Return : 16% z. Break-Even Point (BEP) : 34.91%
