Pra Rancangan Pabrik Ammonium Chlorida dari Ammonium Sulfat dan Sodium Chlorida dengan Kapasitas 10.000 Ton/Tahun

Abstract

Preliminary plant design of Ammonium Chlorida with capacity 10,000 ton/year is planned to be built in industry area Gresik-East Java, in the area of land 24,875 m2 . This chemical plant will be operated for 330 day/year or 24 hours a day with 120 employees. Raw material neededs is Ammonium Sulphate 1,560.157,592 kg/hour and Sodium Chloride 1,377.131,843 kg/hour. The production process will be operated at temperature 100 ̊C, at pressure about of 1 atm using Continuous Stirred Tank Reaktor (CSTR) with yield 95 % . The utility consist of 7,186.9494 kg/hour of cooling water; 8,319.1057 kg/hour of steam; 638.9122 kg/hour of Industrial Diesel Oil (IDO); 430.2009 kg/hour of fuel oil while the power of electricity of about 624.1539 kW provided by PLN. This chemical plant also use generator set as reserve. Based on economic analysis shows thats this chemical plant need to be covered by fixed capital of about Rp 115,895,982,304.31 working capital of about Rp 20,703,553,844.64. The profit before tax is Rp 26,286,198,363.35 while the profit after tax is Rp 15,771,719,018.01. Percentage of return on investement (ROI) before tax is 22.6809 % while after tax is 13.6085 %. Pay out time (POT) before tax is 3.0599 years while after tax is 4.2358 years. The value of break even point (BEP) is 44.58 % and shut down point (SDP) is 12.82 % with Discounted Cash Flow Rate (DCFRR) is 27.68 %. Based on the economic analysis, it is concluded that plant design of Ammonium Chlorida with capacity 10,000 ton/years visible to be built.
