Abstract
The global interest in using natural gas has increased considerably, and some factors such as low cost, safety, availability, environmental advantages, technological development, and its applications especially for gas turbines, have caused petroleum fuels replaced by natural gas. Many technologic solutions proposed in the market are reviewing the challenges and opportunities of using natural gas for the sake of knowing the relevant productive ways. As one of these solutions, in this article, a model for selecting the best fuel in the natural gas value chain through four options has been introduced, Compressed Natural Gas, Liquefied Natural Gas, Dimethyl Ether, and Gas-To-Liquids. Based on a comprehensive study, the criteria affecting the decision are determined. Then, using a Delphi method and expert judgments, 20 final criteria were selected. After that, the criteria were ranked; using a group consensus among the experts with Kendall's coefficient of concordance equal to 0.808. To transform the ranks into the weights, the paper uses the Rank Order Centroid (ROC) method. Finally, the best fuel is determined, with the use of the Combined Compromise Solution (COCOSO) method. The results have shown that at first LNG and then CNG is the best options for Iran. The realities of the world are verifying the accuracy of the model.
