CEFCO Process's patented shockwave technology is an innovative, high-speed contactor that uses collision-impact force to provide energy transfer and superior mixing. This application of shockwave replaces conventional thermodynamics by delivering intense energy and heat upon contact to mix and react chemicals with pollutants followed by processing them in a sub-atmospheric free-jet expansion zone, which rapidly forms, cools and stabilizes the products of reaction.
Designer shockwaves can be customized to user applications to control speed, energy transfer, geometry, vector, length, feedstock driver, and reactants. Shockwaves can be used exclusively or with traditional chemical production methods, such as catalysts, to form unique products. Several applications are concurrently in development featuring this aerophysics-based delivery mechanism.

A multi-million dollar pilot plant was constructed in 2011 to demonstrate CEFCO Process's unique and ultra high-performance method of scrubbing on simulated coal-fired flue gas. This pilot plant, which was designed to capture 99.99%+ of trace metals, PM2.5, SOx, NOx, and CO2 in four unique stages as resalable products, was located in Wichita Falls, TX and involved an external development team. After one year of development, published results included 99.99%+ capture of PM2.5, and SOx.
National energy policy and a downturn in the fossil fuels industry prevented the system from being commercialized at the time. NOx capture and CO2 capture development met indicative success but funding was cut before results could be published.

A multi-million dollar demonstration plant in China was constructed in 2016 with a major, Chinese state-owned power company and is currently undergoing testing and commissioning. This demonstration plant is installed on a 35MWe boiler at a coal-fired power generation plant. This system is designed to capture fly ash, PM2.5, SOx, and NOx to China “Year 2020 Standards.”

“The goal is to reach “China Year 2020 standards,” which is very achievable especially for PM2.5, metals, and SOx. After national adoption, we expect to see blue skies over every major Chinese city in the next five to ten years.”

A portable, skid-based system, designed to capture and manufacture CO2 products at ultra-low cost, was constructed near Dallas, TX. The prototype, using a vertical configuration, was tested throughout 2016. Testing and development was successful and completed in early 2017. The system captures and converts CO2 into sodium carbonate or bicarbonate and is capable of producing up to several tons of solid product a day. Further developments to release the CO2 from the carbon product are underway. Significant breakthroughs were achieved to simplify the system while gaining efficiency. A smaller, horizontal, commercial system and live demonstration will be available in summer 2017.
“The CO2 system processes up to 50#/min (23kg/min) of stack gas per shocktube. The fixed cost of running a shocktube is less than $5/hr of total utility. The goal is to maximize production given this ultra-low OPEX.”
The vertical CO2 system (previously shown for the carbon capture prototype) is being re-purposed as a two-stage flexible flue gas pollutant-scrubber with the ability to target selective pollutants based on user request. The system will be available to be installed at a customer site for testing and demonstration in 2017. More applications are being designed and developed throughout 2017.
