Abstract

Preliminary design of Benzyl Alcohol with capacity 5,000 tonyear is plant to be built in industry area Gresik-East Java, in the area of land 50000 m2. This chemical plant will be operated for 330 dayyear or 24 hours a day with 150 employees. Raw material neededs is Benzyl Chloride 0.7781 ton hour, Sodium Carbonat 0.4479 ton hour, and Water 0.6719 ton hour. The production process will be operated at temperature 100 C, at pressure about of 1 atm using Continuous Steared Tank Reaktor (CSTR) with conveslon 72% . The utiliy consist of 11,145.68 kg hour of cooling water, 806.2285 kg/hour of processing water, 3504.167 kg hour of housing water, 121.8459 kghour of steam, 214.2159 m3 hour offuel while the power of electricity of about 114.664 kwh provided by PLN. This chemical plant also use generator set as reserve. Aneconomic analysis shows thats this chemical plantneedto be covered by fixed capital of about Rp. 179,430,684,521.36 working capital of about Rp.51,298,627,745.51. The profit before tax is Rp.39,731,020,047.53 while the profit after tax is Rp. 19,865,510,024. Percentage ofreturn on investemen (ROI) before tax is 22.1428% while after tax is 11.0714%. Pay out time (POT) after tax is 3.1111 years while after tax is 4,7458 years. The value ofbreak even point (BEP) for about 40.6890% and shut down point (SDP) of about 14.5106%. Based on the economic analysis, It is concluded that plant design of Benzyl Alcohol with capacity 5,000 tonyears visible to be built.
