Pra Rancangan Pabrik Epiklorohidrin dari Diklorohidrin dan Natrium Hidroksida dengan Kapasitas 50.000 Ton/Tahun

Abstract

The rapid development of the chemical, automotive and electronic industries has made the demand for epichlorohydrin increase every year. Currently there is no epichlorohydrin factory in Indonesia so that the industry's need for epichlorohydrin is met from imports. Therefore, the establishment of an epichlorohydrin factory has quite positive prospects for reducing these imports. The preparation of epichlorohydrin begins by reacting dichlorohydrin with sodium hydroxide with a mole ratio of 5 : 1 in 2 stirred tank flow reactors (RATB) at a reactor temperature of 80 ℃ and a pressure of 1 atm. This reaction takes place with an optimum conversion of 95.4% and is exothermic so water cooling is used to maintain the operating temperature. The utilities needed consist of 200183.1275 kg/hour of water, 74 m3/hour of compressed air, 2170.3770 kW of electric power supplied from PLN with a backup generator. The required fixed capital is Rp. 396 billion and working capital of Rp. 420 billion. Production costs (manufacturing costs) are Rp. 2 trillion, and general expenses are Rp. 616 billion. Profit before tax is IDR 100 billion and after tax is IDR 65 billion. This factory is classified as low risk with a Return Of Investment (ROI) before tax of 25.28% and 16.43% after tax. Pay Out Time (POT) before tax is 2.83 years and after tax is 3.78 years). Net Present Value (NPV) IDR 47 billion. Break Event Point (BEP) 40.69 % and Shut Down Point (SDP) 33.13 %.
