New process will lower fracking's carbon footprint and cost

from Vancouver Sun

A University of British Columbia research team is pioneering a water-treatment technology that could significantly reduce fracking's environmental impact. The technology relies on advanced dialysis cells that use carbon dioxide to desalinate wastewater and while producing hydrochloric acid and carbonate salts as byproducts. Because hydrochloric acid and carbonate salts are both used in the fracking process, deriving them from wastewater means they do not have to be purchased, thus saving money, nor do they have to be shipped to the fracking site, saving more money while eliminating the greenhouse gases that would otherwise be associated with the transportation system. Bonus: The carbon dioxide used in the process comes from on-site gas flaring and generator operation. more
