Abstract: A system and method for recovering and separating water vapor and electrolyte vapor from an exhaust stream (22) of a fuel cell uses a membrane tube (72) comprising membrane (74) having an outer wall (76) and an inner wall (78), wherein exhaust stream (22) is directed to contact outer wall (76), electrolyte vapor is condensed on outer wall (76), and water vapor is condensed inside the membrane (74), the condensed water drawn from the membrane (74) to inner wall (78), leaving behind condensed electrolyte (88) on outer wall (76).

Abstract: An emission treatment system includes a separation device having a vessel that includes an inlet for receiving an emission stream having entrained solid particles. A first outlet from the vessel discharges captured solid particles from the emission stream and a second outlet from the vessel discharges a clean stream having fewer entrained solid particles than the emission stream received into the separation device. A particle collector is fluidly connected with the separation device and includes a collection portion for capturing solid particles from the emission stream.

Abstract: An emission treatment system includes a first separation device that is operable to introduce one or more sorbents into an exhaust stream having emission products. The sorbent captures the emission products such that the exhaust stream includes sorbent with captured emission products. A second separation device located downstream from the first separation device receives the exhaust stream and utilizes an electrostatic potential to separate the sorbent with captured emission products from the exhaust stream into a discharge stream to produce a clean stream.

Abstract: A device separates particulates from a gas stream flowing through the device. The device includes at least one high voltage electrode and a substantially cylindrical separator. The high voltage electrode applies a first voltage to the gas stream. The separator has an inlet for introducing the gas stream into the separator tangentially to an interior wall of the separator, a particulate outlet for expelling the particulates from the separator, and a gas stream outlet.

Abstract: A method of separating a coal particle-laden gas mixture into a flue gas recirculation stream and a concentrated sorbent stream includes initiating combustion of a mixture of air and coal in a combustion chamber, extracting a mixture of flue gas and partially-combusted coal particles from the combustion chamber, inducing flow of the mixture of flue gas and partially-combusted coal particles toward a core separator apparatus, and separating the mixture of flue gas and partially-combusted coal particles into the flue gas recirculation stream and the concentrated sorbent stream using a centrifugal action of the core separator apparatus. The recirculation stream and the concentrated sorbent stream flow out of the core separator apparatus on a substantially continuous basis.
