Abstract

Boric acid has the molecular formula H3BO3 have an important role in various industries, both as an adjuvant in the glass industry, ceramic coatings industry, bleach in chemical industry, and materials in the manufacture of drugs in the pharmaceutical industry. The boric acid plant designed to meet domestic demand. The boric acid plant designed capacity of 11.000 ton/year. The process of making this boric acid using the acidification process with mole ratio of borax:sulfuric acid = 1:1,01. The reaction is exothermic and is run in a continue strirred tank reactor (CSTR), liquid-liquid phase, irreversible and kept isothermal operating conditions and pressure of 1 atmosphere with raw materials borax as many as 1.223,07 kg/hr and sulfuric acid as many as 384,56 kg/hr. Process support unit includes a water supply unit as many as 5.579,87 kg/hr is obtained from Brantas river water, units procurement steam with the needs of 52,646 kg/hr, units procurement of compressed air at 60,48 m3 per hour, units procurement of electricity from PLN and generator set as many as 400 kW for backup, as well as fuel procurement unit of IDO at 58,72 liter/hour. The factory is planned to be established in the industrial area of Gresik, East Java with land area of 25.550 m2 and the number of employees as many as 139 people. The results of the economic analysis, the boric acid plant requires a fixed capital of Rp 346.313.089.667,77 and working capital of Rp 79.924.962.676,07. Profit before tax of Rp 105.233.369.792,84/year. Profit after tax of Rp 94.710.032.813,56/year. Feasibility analysis results obtained from the Return On Investment (ROI) before tax of 30,39% and after tax of 27,35%. Pay Out Time (POT) before tax of 2,48 years and after tax of 2,68 years. Break Even Point (BEP) of 46,59%, and Shut Down Point (SDP) of 24,05%. Discounted Cash Flow (DCF) of 33,66%. The results of the economic analysis concluded that the plant boric acid from borax and sulfuric acid using acidification process capacity of 11.000 ton/year feasible to set. Keywords : boric acid, borax, acidification process, continue stirred tank reactor (CSTR)
