Life Cycle Assessment for Coal Derived Methanol Transportation Pathway

Abstract:

According situation of the existing coal to methanol industry, we used life cycle assessment method, established a coal to methanol model for transportation pathway. Comprehensive assessment of its energy efficiency, CO₂ emissions and economic costs performance. In terms of energy efficiency, coal-to-methanol for transportation pathway is 9.51%, and terminal power consumption accounts for 31% of the entire model. In terms of CO₂ emissions, the CO₂ emissions is 892.27g/MJ of whole model. In methanol production processes, it emissions a lot of CO₂ and loses a lot of energy. In terms of economic cost, the methanol produced by coal-to-methanol technology is able to make a profit.
