Prarancangan Pabrik Carboxymethyl Cellulose Dari Cellulose Proses Continue Wyandotte Dengan Desain Alat Utama Rotary Dryer (Rd-101)
Carboxymethyl Cellulose is an organic compound with the molecular formula C8H11O7Na which is a derivative of cellulose which is commonly used in various industries such as the detergent, paint, ceramics, textile, paper and food industries. The main raw materials used in making carboxymethyl cellulose using the Wyandotte Continuous Process are cellulose, monochloroacetic acid and sodium hydroxide. This factory is planned to operate for 330 days per year and work continuously 24 hours/day with a capacity of 6,000 tons/year which will be established in the city of Babakan, West Java. The company form chosen is a Limited Liability Company (PT) with a line and staff organizational system. The employee work system is based on the division of working hours consisting of shift and non-shift employees. The main equipment design in this factory is the Rotary Dryer (RD-101) which functions to reduce the water content of carboxymethyl cellulose to the remaining 5% using hot air at a temperature of 105°C . Economic analysis in the design of this factory shows that this factory is feasible to build. With a Break Event Point (BEP) value of 58%, Pay Back Period (PBP) of 4.1 years, Rate of Investment (ROI) of 16.19%, and Interest Rate of Return (IRR) of 22.75%.
Keywords: Carboxymethyl Cellulose, Cellulose, Continue Wyandotte Process, Rotary Dryer.
