Summit Power (Texas Clean Energy Will Use Scrubber and Wastewater Treatment )
The Venturi scrubber system will require lots of wastewater treatment. Siemens has systems with two venture scrubbers and a demister all with bleed streams to wastewater treatment

In addition to his duties as President, Eric Redman heads Summit’s development of carbon capture projects. He is a frequent speaker and author on coal gasification, carbon capture and carbon management, enhanced oil recovery, and climate matters. Mr. Redman’s seminal book on Congress, “The Dance of Legislation” was a bestseller; he has also written for many newspapers, anthologies, and magazines.
He holds a BA and JD from Harvard and an MA from Oxford, where he was a Rhodes Scholar. Mr. Redman serves on the Board of Directors of the Gasification Technologies Council and has served on numerous non-profit boards.
Barry Cunningham has over 30 years of experience in the power industry and has held positions in a variety of disciplines.
Laura Miller joined Summit in 2008 to work on the Texas Clean Energy Project, an integrated gasification combined cycle (IGCC) project. She served as Mayor of Dallas from 2002 to 2007.
Siemens is the primary equipment provider for Texas Clean Energy Project’s gasifiers, power island and controls, including a “twin pack” of SFG-500 gasifiers, a state-of-the-art SGT6-5000F combustion turbine, and an advanced SPPA-T3000 control system. Siemens will also supply O&M services for the facility.
On the TCEP project, Linde will be designing and costing the handling of the synthesis gas produced by the Siemens gasifiers, including, shift and gas cooling, Rectisol® wash unit, cryogenic nitrogen wash unit, CO2 compression, mercury removal, sulfuric acid production, ammonia production and urea production. Linde will also design an air separation unit for the delivery of nitrogen and oxygen to the gasifiers and combustion turbine.
Selas Fluid Processing Corporation, a subsidiary of The Linde Group, is headquartered in Blue Bell, Pennsylvania. The Company provides combustion-based technologies for hydrocarbon processes throughout the world. Core products and capabilities include complete hydrogen, synthesis gas and air separation plants, process furnaces, fired heaters, cryogenic vaporizers, and thermal oxidation systems for the refining, petrochemical, pharmaceutical, gas and chemical industries.
Whiting will purchase 80 million cubic feet (80,000 Mcf/d) of compressed CO2 per day from TCEP—representing approximately 60% of TCEP’s total volume of captured CO2—during the first five years of TCEP’s operation, with gradually declining amounts and an option to extend the purchases thereafter. In the Permian Basin, approximately one additional barrel of oil can be recovered for each 6,000 cubic feet (6 Mcf) of compressed CO2 injected into the oil field. TCEP will begin delivering CO2 to Whiting when the plant commences operations in late 2014 or early 2015;
In oil fields such as Whiting’s, the injected CO2 mixes with the oil that is left behind in the primary oil-well production and the secondary water-injection stage. Approximately 40% of the initially injected CO2 remains trapped underground. The remainder comes to the surface with the oil, but is then recaptured, recompressed, and re-injected. Ultimately, some 99% of the injected CO2 can be permanently stored (i.e. geologically sequestered) deep underground many thousands of feet below the water table, with no leakage to the atmosphere.
