Frac water recycling on-site
GE’s new, completely mobilized evaporator is designed to enable on-site frac water recycling, reducing the volume of wastewater and fresh water that needs to be hauled to and from the project site. The mobile evaporator will enable natural gas producers to significantly decrease their transportation and disposal costs. Additionally, the communities will benefit from less truck traffic and decreased wear and tear on local roads.
The mobile evaporator is a 50-gallons-per-minute (gpm), truck-mounted, mechanical vapor recompression (MVR) system. It features a well proven and robust, horizontal shell and tube, forced circulation evaporator.
Through its robust design and compact footprint, the mobile frac evaporator will be able to treat all types of unconventional gas wastewater streams throughout the world, including shale gas frac water applications and coal bed/seam methane applications.
The initial application will be treating frac water in the Marcellus Shale. The Marcellus Shale is unique in that it produces very high total dissolved solids (TDS) frac water, has limited deep well capacity and increasingly stringent discharge regulations.
The Mobile Frac Evaporator provides greater reliability, higher on-stream availability, lower power consumption and reduced fouling of heat exchange surfaces as compared to systems currently in use for frac water recycling. The mobile frac evaporator is a truck-mounted design that fits within one standard trailer—a truly mobile system with straightforward setup and operation.
