Mobile evaporators treat shale gas frac water

Natural gas producers will be helped in recycling untreated hydraulic fracturing waters at the well site with this newly introduced mobile evaporator. It is specifically designed to help treat shale gas frac water on site.

The completely mobile evaporator is energy efficient, fully transportable, and will reduce wastewater and fresh water volumes needed to be hauled to-and-from a site. To offset hydraulic fracturing environmental impact, the new evaporator will treat severely impaired waters (frac flowback and produced) for industrial process reuse, it’s noted. It will also help reduce the amount of fresh water consumed.

The new evaporators are 50-gpm, horizontal, shell and tube, forced circulation, mechanical vapor recompression systems. Thermal evaporation removes nearly all impurities in water, allowing producers to easily meet newly passed Pennsylvania discharge regulations of less than 500 TDS, notes the manufacturer. The mobile units mount on a single trailer to reach remote drilling sites.

The new designs will be used for all unconventional gas and frac water applications in global regions where shale gas is found. Initial applications will be in various North American markets. These include the Marcellus Shale reservoirs in the Appalachian Basin. Units will be available early 2011.
