Fact Sheet
Mobile Evaporator Treat Shale Gas Flowback and Produced Water at
the Well Site
Product Overview
GEs new, completely mobilized evaporator is designed to enable
onsite flowback and produced water recycling, reducing the volume
of wastewater and fresh water that needs to be hauled to and from
the 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 gallon per minute (gpm),
truck-mounted, mechanical vapor recompression (MVR) system. It
features a well-proven and robust, horizontal shell and tube,
forced circulation evaporator.
Typical Applications
Through its robust design and compact footprint, the mobile
evaporator will be able to treat all types of unconventional gas
wastewater streams throughout the world, including shale gas
produced water applications and coal bed/seam methane
applications.
Regions like the Marcellus Shale are unique in that they produce
very high TDS flowback and produced water, have limited deep well
capacity and increasingly stringent discharge regulations.
General Properties
The mobile 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 gas well return water recycling.
The mobile evaporator is a truck-mounted design that fits within
one standard trailer - a truly mobile system with straightforward
setup and operation.
Key Properties Include:
Robust heat exchanger configuration
MVR (high efficiency) design can reduce energy costs by
approximately 35%
Reduced fouling rates
Easy access for cleaning and maintenance
Excellent on-stream availability
Mobile design fits within one standard trailer
No site support equipment (cranes, etc.) required
Completely self-contained with all ancillary equipment included
within the trailer
Single drop trailer provides maximum clearance for remote site
access
