Gas-to-Liquids (GTL) Technologies has emerged as a viable industry over the past thirty years offering market diversification to remote natural gas resource holders. GTL technologies includes more than Fischer–Tropsch technology and extends to other liquid fuels, especially in the oxygenate family (methanol, dimethyl ether, etc.). This study is a safety analysis on a DME plant. Currently, efforts are to commercialize DME as a high-quality diesel alternative. KOGAS has developed a process in which syngas is produced from natural gas and converted to DME using a single reactor, unlike the conventional 2 stage processes having methanol as intermediate. The purpose of this study is to first obtain the most updated simulation of the plant using Aspen Plus® based on the already existing simulation results and then to apply risk analysis to quantify the individual and societal risks of operating such a large scale DME plant by making use of Phast and Safeti QRA software and suggest necessary changes in case the risks are above the acceptable limits. |
