Project Engineering: Nickel Refinery Water Improvement
A nickel refinery based in the United Kingdom required support to reduce the negative impacts of importing canal and river water into the site for the purpose of cooling water.
InSite Technical Services completed a conceptual report identifying and evaluating potential options and recommending a preferred option. Water samples were taken and tested to determine the solids loading and particle size distribution. This provided the basis on which available particle removal technologies were evaluated. Extensive research was undertaken on the suitability of products currently on the market.
The preferred solution would be a combination of modifications to address the issues. These included:
- Installation of pre-pump screens
- Replacement of the canal water pumps to improve reliability and reduce the requirement to utilise river water
- Install post-pump filters to reduce fouling problems in the downstream cooling water system
- Install a canal abstraction flowmeter to allow for total abstraction rate to be measured
