New project sets to change the water treatment game at Natural Gas sites

Techbeing tested is predicted to reduce the need of transporting water for disposal and maintaining local water balances, while reducing operating costs.

Geoscience BC and NGIF Industry Grants (a division of NGIF Capital Corporation) are supporting Saltworks Technologies Inc. to develop its AirBreather evaporator-crystallizer.

Saltworks’ AirBreather Pilot uses excess heat from natural gas production to efficiently and effectively treat produced water on-site. The project will test its innovative evaporation system on saline (salty) produced water samples, collected from natural gas operations in the Montney Play in British Columbia’s Northeast Region. Produced water is water that flows to the surface with gas and oil during the production process.

 AirBreather units turn saline produced water into clean water for reuse, or into water vapour for safe release into the atmosphere. Saltworks has estimated that the natural gas sector spends approximately $180 million per year managing ponds and transporting saline water from production sites in northeastern BC. The technology being tested is predicted to reduce the need of transporting water for disposal and maintaining local water balances, while reducing operating costs.

“On-site treatment with AirBreather cuts the number of trucks on the road hauling wastewater between sites, reducing greenhouse gas emissions and the impact of natural gas operations,” said Henry Tsin, project lead and Vice President of Commercial Development at Saltworks Technologies Inc. “We estimate that on-site water treatment saves 30% over the cost of traditional disposal methods.”

AirBreather testing will take place at Saltworks’ Richmond, BC facility, using samples of produced water from BC’s Northeast region, where hundreds of natural gas production sites produce approximately 87 per cent of BC’s natural gas from the Montney Play.

“Saltworks’ AirBreather is an inventive evaporation alternative that is designed to garner positive environmental results,” said John Adams, President and CEO of NGIF Capital Corporation. “NGIF is proud to once again support Saltworks as they demonstrate a commitment to innovation, affordability, and environmental performance.”

Geoscience BC Executive Vice President and Chief Scientific Officer Carlos Salas said, “Geoscience BC aims to use advanced science and innovative geoscience technologies to improve the environmental and economic competitiveness of Montney Play natural gas operations. Supporting Saltworks’ made-in-BC AirBreather is an important step towards meeting that goal.”

“Supporting Saltworks’ AirBreather is yet another example of the gas industry’s commitment to work across the value chain to improve environmental performances while maintaining reliable, affordable energy services,” said Timothy M. Egan, President and CEO of the Canadian Gas Association and Chair of NGIF Capital Corporation.
