Prarancangan Pabrik Pembuatan Metil Klorida Menggunakan Proses Hidroklorinasi Metanol dari Bahan Baku Metanol dan Asam Klorida Serta Katalis Zinc Klorida dengan Kapasitas Produksi 15.000 Ton Tahun

Abstract

Preliminary design of methyl chloride using hydrochlorination methanol process from methanol and hydrogen chloride with zinc chloride as catalyst with production capacity of 15,000 tons/year and operate for 330 days in a year. The main process in the preliminary of this plant consists of two stages, the methyl chloride formation stage with hydrochlorination reaction and the cooling and purification stage. In the preliminary design of this methyl chloride, we will use a fixed bed multitube reactor. The reactor operates at 150°C; 2 atm which requires 1226,8020 kg/hour of methanol, 3696,7409 kg/hour of hydrochloric acid with 48,5668 kg/year of zinc chloride catalyst. In the hydrochlorination process, the methyl chloride conversion was 98,12% and the purity was 99,99%. The plant location is planned in Tanara District, Serang, Banten with an area of 13,334 m2. The factory's water needs come from the Cidurian River. The factory's electricity using an electric generator with a power of 118,969 kW. The planned form of business entity is a Limited Company (PT). The planned form of organization is a line and staff organization with a required workforce of 127 people. The result of the economic evaluation of the Methyl Chloride Manufacturing Factory are as follows:  Capital Investment (CI) : Rp 689.868.596.753  Total Cost (TC) : Rp 545.034.770.932  Sales Proceeds : Rp 720.000.002.304  Net Profit : Rp 138.397.498.015  Profit Margin (PM) : 23,0857%  Break Even Point (BEP) : 47,3483%  Return on Investment (ROI) : 20,0614%  Pay Out Time (POT) : 4 years 11 months  Return on Network (RON) : 33,4357%  Internal Rate of Return (IRR) : 18,7%
