Siemens Energy is supplying SNF SAS, France, a chemical company that specializes in polymers, with a produced water treatment system as part of the company’s plant expansion in the Petrocedeño oil field, located in the Orinoco Belt in Venezuela. The system includes a Spinsep vertical flotation unit and a Monosep high-flow walnut shell filter to treat 10,000 barrels per day of produced water as part of the Petrocedeño EOR Polymer Field Test Project. The equipment is scheduled to be operational by the end of October 2012 and will be deployed onsite in 2013.
The produced water treatment system used on this project will enable the polymer plant to mix the treated water with its polymers for reinjection in the well to enhance oil recovery. Water will first flow to the Spinsep system for primary oil/water separation and then flow through the Monosep high-flow walnut shell filter for tertiary treatment.
The vertical design and compact footprint of both the Spinsep flotation system and the Monosep high-flow walnut shell filter makes the system more economical than a typical flotation system. Additionally, the internal scrubbing design of the walnut shell filter eliminates external backwash system and its associated pumps, making operation easier and more trouble-free.
SNF is a manufacturer of polymers used in water treatment, oil and gas, and mineral extraction applications. It is headquartered in France, with several research and development and production facilities throughout Europe, the Americas and Asia. SNF SAS is the contracting company for this project.
Petrocedeño is a joint venture between Venezuela-based PDVSA (60%), France-based Total (30%) and Norway-based Statoil (10%). It is exploiting oil fields in the Orinoco belt of Venezuela. PDVSA is in charge of operating and developing the fields on this project.
