Solution
Advantages of LEWA Produced Water Treatment Packages:
- The system is hermetically tight and leakage-free.
- With the system, even small flow rates (~ 1 l/h) can be realized.
- Corrosion-resistant materials are used (e. g. 6Mo, super duplex), so that the system is suitable for biocides.
- Pneumatic or electric stroke length adjustment allows proportional flow control.
- The diaphragm pumps have an integrated diaphragm monitoring system (local or remote), which prevents unexpected shutdown and the concomitant maintenance costs.
- Plug & play packages reduce commissioning time.
Background
What is produced water, and how does it come about?
Water that is conveyed along with oil during oil production is called produced water. This water mostly comes from underground layers of water located in the immediate vicinity of the oil deposit. Particularly in the case of older bore holes, it is often necessary also to introduce water or steam so that the oil can still be conveyed. Then the oil being produced contains this water, too. After the oil is purified, the so-called produced water is left behind. The longer a bore hole is in use, the more the percentage of oil being produced decreases, while the percentage of water increases. The produced water still contains hazardous and toxic substances, which must not be allowed to flow back into the natural water cycle.
Produced water treatment packages purify the produced water by removing residual oil and all other contained substances, such as gases, sand, heavy metals and biological and chemical residues.
In accordance with international and regional requirements, the water must meet strict purity specifications before it can return to the water cycle. The IMO (International Maritime Organization) has defined limit values for the percentage of residual oil in the produced water, which are at 15 ppm, in some sensitive maritime regions even at 5 ppm.
