System Cleans ‘Produced Water’ from Natural Gas Wells
Increased natural gas production is seen as a crucial step away from the greenhouse gas emissions of coal plants and toward U.S. energy independence. But natural gas wells have problems: large volumes of deep water, often heavily laden with salts and minerals, flow out along with the gas. That so-called “produced water” must be disposed of, or cleaned.
Now, a process developed by engineers at MIT could solve the problem and produce clean water at relatively low cost. After further development, the process could also lead to inexpensive, efficient desalination plants for communities in the developing world, the researchers say.
