Comparative efficiency of long-distance transportation of national gas and coal

The authors compare different combinations of processing technologies and long distance transportation of natural gas and coals from the fields of the eastern areas of the country. In the result of optimization estimations of different variants of power transmission, the spheres of their effective use are outlined. It is concluded that the variant of large-scale production of methanol and DME with their subsequent long-distance pipe-lining can be viewed as an alternative to long distance transmission of large volumes of gas.
