Hydrogen Fluoride Substance Flow Analysis: In Case of the Chemical Industry in South Korea

Abstract : Up to date, many chemical accidents were occurred in the world. We know that recently there was a big chemical explosion accident and its expose of toxic chemicals in Tianjin, China. According to the Korean Ministry of Environment, the number of chemical accidents was increased 7 cases in 2006 to 104 cases in 2014. Therefore, it should be considered and conducted many studies on sustainable chemical substance’s safety management and prevention of the chemical accidents as well as establishment of related chemical management regulations. In this study, we selected and studied about hydrogen fluoride (the chemical formula HF, CAS NO: 7664-39-3). This colorless gas or liquid is the principal industrial source of fluorine, often in the aqueous form as hydrofluoric acid, and thus is the precursor to many important compounds including pharmaceuticals and polymers (e.g. Teflon). HF is widely used in the petrochemical industry and is a component of many superacids. In this study, we quantified, analysed and mapped the HF flows in the chemical industry of South Korea by applying substance flow analysis (SFA). Our result shows that the amount of consumption in each company (and industry), location of manufactures using HF as well as HF’s flow (import, export, stocks and flows) in Korean industrial system (between industries including companies). Finally the result of this study can support for chemical accident prevention system and sustainable chemical management in South Korea.
