Effects of hardness ions on valuable element recovery in oilfield produced water: Mechanisms and implications
“In response to the issue of the influence of hardness ions on the purity of valuable element recovery in oil and gas production water, experts have proposed the nuclear crystal granulation technology for removing hardness. After optimizing the process parameters, the removal rates of calcium and magnesium ions reached 94.5% and 85.3%, respectively, and the loss rate of valuable elements was less than 20%. This provides a new idea for efficient separation of hardness ions and recovery of valuable elements.”
