Ke tien Liu, Herman Nack: NO.sub.X reduction in multisolid fluidized bed combustors. Battelle Development Corporation, Barry S Bissell, November 3, 1987: US04704084 (29 worldwide citation)

Nitrogen oxide pollutants are substantially reduced and sulfur dioxide minimized in multisolid fluidized beds by staged combustion of the fuel. The lower combustion region is operated at substoichiometric conditions such that NO.sub.x is reduced by carbon and carbon monoxide to nitrogen gas. The upp ...

Ke Tien Liu, William Rieken: Multiphase flow measurement method and apparatus. Accuflow, Townsend and Townsend and Crew, March 7, 2000: US06032539 (24 worldwide citation)

The invention provides an apparatus (100) for separating at least a first component (e.g., liquid, etc.) from a second component (e.g, gas or vapor, etc.) from a multiphase fluid during non-ideal flows such as plug flow operation. The apparatus (100) generally has a first line section (111) tangenti ...

Herbert Liu, Ke Tien Liu: Multiphase flow measurement apparatus and method. James M Duncan, Klein DeNatale Goldner, December 25, 2007: US07311001 (2 worldwide citation)

An apparatus is utilized for obtaining flow measurements from an individual oil and gas well. The apparatus utilizes pipe segments rather than vessels to separate the fluid components into a gas phase, a water phase, and an oil phase. Separation of the flow stream into the different phases allows th ...
