The economic feasibility of mentioned industrial project was also analyzed, which was shown in Table 9. The production capacity of ethanol, CNG and LPCM is 20,000 t/y, 1000,000 m3/y and 60,000 t/y, respectively. The production cost of ethanol is divided into materials cost, variable operation cost, fixed operation cost and investment cost. The costs of ethanol production are largely dominated by materials costs and investment costs, while fixed and variable operating costs play a minor role.
