GE introduces a mobile evaporator for the purpose of assisting natural gas producers in recycling untreated waters that result from the hydraulic fracturing process at a well site. The new system is an effort by GE to advance a solution for unconventional gas production. The new completely mobilized evaporator is full transportable, as well as energy efficient and cost effective. The system will allow onsite frac-water recycling, minimizing the volume of wastewater and freshwater needed to be hauled to and from the site.
Significant amounts of natural gas and oil exist deep below the surface of the earth, within shale reservoirs, which lack the natural permeability to reach the surface for recovery. The hydraulic fracturing process, involving the creation of small fractures in the rock around the reservoir as a path for natural gas and oil to flow, has allowed production from oil and gas resources that were otherwise considered unrecoverable.
The hydraulic fracturing process increases the production rate of oil and gas wells, however also uses a large amount of freshwater and produces billions of gallons of wastewater annually. GE’s mobile evaporator offsets the environmental impacts of that process by treating severely impaired waters, such as frac flowback and produced water. The system makes it possible to reuse the water in the industrial process, reduce consumed fresh water and minimize subsequent environmental impact from discharge.
The mobile evaporator will be used in unconventional gas and frac water applications in areas where shale gas can be found, including China, Europe, Indonesia and North America. Initial applications will be in various North American markets such as the Marcellus Shale reservoirs located in the Appalachian Basin.
“GE’s objective is to create a solution that not only lessens the environmental impact of gas drilling, but also one that reduces the current treatment cost to service providers and producers. As the mobile evaporator illustrates, our research and development teams are continually working toward offering new solutions to meet our customers’ challenges throughout the industry,” stated Jeff Connelly, vice president, engineered systems—water and process technologies for GE Power & Water.
