NOVELTY - Producing electrical power from a syngas comprises purifying the syngas to remove at least one impurity; enriching the syngas via subjecting it to a water-gas shift reaction to produce a product relatively enriched in hydrogen and carbon dioxide; reacting the purified, enriched syngas within a fuel cell to produce electrical power and a fuel cell anode exhaust stream; and separating the fuel cell anode exhaust stream to produce a first separator stream relatively enriched in water.    USE - The methods are useful for producing electrical power from a syngas and for separating carbon dioxide and water (all claimed).    ADVANTAGE - The present invention provides improved systems and methods for the separation of carbon dioxide from water.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are:    (1) a system, for producing electrical power from a syngas, comprising: a fuel cell configured to produce electrical power from syngas; a purification unit upstream of the fuel cell, the purification unit configured to remove at least one impurity from a syngas stream; a water-gas shift reactor upstream of the fuel cell, the water-gas shift reactor configured to produce a stream enriched in hydrogen and carbon dioxide relative to the stream fed to the water-gas shift reactor; and a separator configured to produce a stream relatively enriched in water from a feed stream comprising or derived from at least a portion of a fluid product of the fuel cell; and    (2) a method of separating carbon dioxide and water by (A) separating a first fluid stream comprising carbon dioxide and water within a first flash drum to create a second fluid stream enriched in water relative to the first fluid stream; and separating the second fluid stream comprising carbon dioxide and water within a second flash drum to create a third fluid stream enriched in water relative to the second fluid stream; or (B) separating, without the use of a non-aqueous solvent, a first fluid stream comprising carbon dioxide and water within a first separation unit to produce a second fluid stream containing at least 99.8 wt% water.
