Oil and gas reservoirs have a natural water layer (formation water) that lies under the hydrocarbons. Natural gas production is seen as a crucial step away from the greenhouse gas emissions of coal plants. But natural gas wells contain 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.
A new process is developed by engineers at MIT and collaborators at King Fahd University of Petroleum and Minerals (KFUPM) to produce clean water at relatively low cost. Researchers say, after further development, the process could also lead to inexpensive, efficient desalination plants for communities in the developing world.
MIT Mechanical engineering professor, Lienhard says, “We became interested in the humidification dehumidification (HDH) process at the start of our collaboration with KFUPM as a means of providing water to off-grid regions of the developing world. Both the MIT and the KFUPM faculty wanted to develop a technology that might benefit people all over the world.”
The work was supported by KFUPM through the Center for Clean Water and Clean Energy at MIT and KFUPM.
