Energy Water Solutions (EWS), a scalable oil field services organization whose focus is evaporative technologies for the oil and gas and industrial markets, announced on Dec. 10 that the U.S. Patent and Trademark Office has issued a patent to EWS recognizing the innovative and unique methods used in the company’s proprietary VOX (Vaporization in a Box) evaporative technology and the breakthrough nature of its performance in the field.

EWS' VOXTM technology is currently being used in the oil and gas production market. The VOX 4 product not only offers cost-effective evaporation of produced water, it also benefits from its extremely low emissions profile enabling streamlined permitting. Its modular nature provides operators’ the ability to quickly scale up or down based on the wellpad needs. The VOX’s superior performance and the ability to quickly penetrate the produced water market with its build/own/operate operating model, motivated EWS to pursue a patent to protect its unique technology, according to a company release.

The patent covers the overall containerized system—the wastewater feed, the drip manifold, the packing and tray system, and integrated air system. All of these components make up the VOX technology. Altogether, the Patent contains 99 claims and is valid until November 2031. While the produced water market is large, the company continues to work on additional applications for the VOX technology to expand the company’s ability to serve a broader market.

“We are extremely pleased with the USPTO’s (U.S. Patent and Trademark Office) recognition of our VOX technology. Our VOX 4 product offers a step-change improvement in performance and will only strengthen and expand our footprint as the leader of low emission, evaporative technology as it relates to produced water. We believe this patent is an important milestone and we will continue to focus on fabrication and commissioning of VOX units,” said Paul Kleinen, president of Energy Water Solutions.
