METHODS FOR TREATING PRODUCED WATER

摘要

Produced water from fraccing operations is treated by removing contaminants that are contained therein by evaporating the produced water and feeding the evaporated produced water to a combustion chamber preferably along with an oxygen gas and a hydrocarbon fuel source to separate solids from vapors. The vapors are condensed to produce liquid water and waste gases and the liquid water is recovered for reuse or more environmentally friendly disposal. The waste gases may also be employed in a turbine or expander to produce electricity.
