Patent number: 7901485Abstract: Vortex gas separation is forced in radial counterflow between counter-rotating coaxial centrifugal impellers. Feed is at the axis of rotation. Axial extraction of nitrogen and water vapor is driven by an axial pump and by back pressure from the tank while radially outward flow of carbon dioxide and scrubbing targets is driven by the impellers. Scrubbing of the concentrated targets is in high turbulence during a long residence time. Tiny centrifugation effects of innumerable turbulent eddy vortices in a shear layer between the impellers and in the tank are integrated by the forcing regime of the impellers and the axial pump. Radial vortices caused by shear between the counter-rotating impellers provide coherent sink flow conduits for axial extraction of nitrogen ballast. Fine fly ash (PM-2.5) scrubbing is concurrent with NOx and SOx scrubbing and with carbon capture.Type: GrantFiled: July 11, 2007Date of Patent: March 8, 2011Assignee: McCutchen Co.Inventor: Wilmot H. McCutchen
