Produced water treatment

Produced water from oil and gas extraction must be treated to remove contaminants before it can be safely discharged or reinjected. GEA provides efficient and cost-effective processing systems for this purpose ensuring environmental protection and compliance with regulations.

Benefits of our centrifuges
  • Efficient de-oiling of produced water
  • Separation of fine particles
  • Continuous operation with patented self-cleaning sludge removal system
  • Reduce residual oil content to max. 5 ppm, meeting IMO standards
  • Reduced disposal costs
  • Space-saving design
  • Low energy consumption
  • Significant reduction in operating costs
Meeting IMO regulations

Across various processes in the oil and gas industry, including the treatment of produced water, strict adherence to environmental regulations is crucial. To meet the standards set by the International Maritime Organization (IMO), GEA offers specialized high-performance, self-cleaning centrifugal separators and clarifying decanter centrifuges. The goal is to efficiently reduce the oil content to levels below the legally specified limits, often set at 15 ppm or 5 ppm in some regions.

Suitable for offshore and onshore use

GEA's self-cleaning disk-type centrifuges are widely used on drilling vessels and platforms globally, delivering reliable and efficient performance. Thanks to their direct drive and the fact that they are not affected by movements of the vessels, these machines are perfect for offshore tasks but are equally suitable for onshore usage. Depending on the specific requirements, our machines are also available in gas-tight and explosion-protected versions.

Mainstream treatment

Disk stack centrifuges play a crucial role in the mainstream treatment of produced water. Utilizing centrifugal force, these machines efficiently separate fine oil droplets and solid particles from the water. Integrating disk stack centrifuges into the treatment process ensures improved clarity and purity, complying with environmental standards for safe disposal or reinjection.

Sidestream treatment

Decanter centrifuges are vital in the sidestream treatment of produced water. These robust machines efficiently separate solids from liquids by using high-speed rotational forces, making them ideal for handling large volumes of water with high solid content. Incorporating decanter centrifuges into the produced water treatment process significantly boosts the elimination of suspended solids, thus enhancing water quality.
