Hydrocyclones: A Solution to Produced-Water

Produced water represents an increasing portion of the total produced fluids during the life of a field. Although the treatment of produced water offers no direct economic incentive, a considerable portion of both engineering and operations time is spent modifying and maintaining produced-water cleanup systems to ensure satisfactory operation.

2021-6-25  Hydrocyclones and dissolved air flotation (DAF) tanks are installed on our offshore platforms to treat suspended hydrocarbons and ensure the quality of produced water. But this equipment cannot remove dissolved organic compounds, which is a problem now that a new E.U. regulation requires the industry to demonstrate that it has largely detoxified water discharged close to production sites.
