NORAM
Engineering and Constructors Ltd (Vancouver, B.C.) has received an
order for the first Generator Acid Purification (GAP™) system for a
Kraft mill.
The GAP™ system converts waste sodium sesquisulfide from ClO2
generators into re-usable sodium sulfate and sulfuric acid. Both
products can be used in the pulping process, thus eliminating a waste
product and saving on chemicals.
The GAP™ system,
developed by FPInnovations and Eco-Tec Inc., is based on the
technologically-advanced Eco-Tec short bed ion exchange system. Over
1,500 such installations find application in the metals industry, but
this application represents a first for the pulp and paper sector.
Inputs to the process are minimal, as only water is required for resin
bed regeneration. Escalating chemical costs in the industry, and the
low GAP™ operating costs, are expected to drive widespread uptake of
the technology. Start-up at the North American site is expected in
early 2009.
