The range of prices for alternative liquid fuel (ALF) produced by the installations, depending on the cost of consumed fuel, price of supplied electric power and level of capital investments, has been ascertained. The studies made suggest the conclusion that combined production of dimethyl ether is more efficient from the energy and economic viewpoints than methanol production. Besides, a certain level of oil prices was identified,...
