Aquatech bangs drum for flash thermal process in reuse
Water and wastewater technologies firm
OTF is designed to recycle heat to convert produced water into clean water with high
purity. It can reduce power consumption by up to two fifths claimed Aquatech.
The process captures heat from the Once-through Steam Generators (OTSGs) that
are commonplace in the Alberta Oil Sands market to use in a thermal desalination
“Based on the proven and robust vertical-tube falling film design principles, the OTF
technology reduces power consumption by 20-40%, lowering operating expenditure. In
addition, it features a simpler process configuration than conventional designs and is able
to deliver a substantial capital cost savings of more than 10%,” said Aquatech’s
applications engineering manager, Greg Mandigo,
OTF yields water recycle rates of more than 95%, and so complies with the Alberta
energy regulation said Aquatech. OTSGs typically allow recovery rates between 80-90%.
