The coal-oil industrial layout evaluation based on water footprint theory

"The Water Footprint Concept" as introduced by Hoekstra (2002), indicates the consumption of water needed for the production of the goods and services in a certain period of time consumed by any of the known population. The products and services referred here contain the necessary human food, all kinds of daily necessities, domestic water and environmental water. Green water, Blue water and Gray water are the three components of the water footprint. Coal Oil/CTL, also known as Coal Liquefaction, is short for the coal chemical technology of producing liquid fuels and chemical raw materials based on coal. Based on water footprint theory, we calculated the blue water footprints and gray water footprints of the planned coal-oil industries in the nation's five largest coal bases: Shendong, Jindong, Ningdong, Shanbei and Xinjiang Yili. All in all, the coal-oil industry layout planning should follow the principles of supply-side management and be based on local water resources and water environmental capability.
