Abstract: A recovery plant for recovery of a gaseous component, such as carbon dioxide, from a process gas, such as the exhaust from a combustion turbine, has an absorber (110) employing a lean solvent (126) in an upper section of the absorber and a semi-lean solvent (172) in a lower section of the absorber. A regenerator (120) extracts the gaseous component from the rich solvent (117) thereby producing a regenerated lean solvent (126) and a semi-lean solvent (127). A solvent flow control element (170) combines at least a part of the semi-rich solvent (118) from the upper section of the absorber with the semi-lean solvent (127) from the regenerator to form a mixed solvent (171), and a cooler (112) cools the mixed solvent that is subsequently fed into the lower section of the absorber (110). By cooling the mixed solvent prior to entry into the absorber, the thermal energy required to remove the carbon dioxide from the exhaust gas can be reduced.

Abstract: A topocompositional image of an inanimate object or surface can be generated that comprises data that relates to a topographical image, data that relates to a chemical compositional image, and combining such topographical and chemical compositional data to form a composite image. Conceptually a laser or other suitable imaging source that functions to induce both topographical and chemical compositional data directs a laser beam into a scanning optics source. The scanning optics source directs an active beam to a point on a surface. A sensor subsequently collects data and information from the surface by receiving the reflection or deflection of the active beams in order to provide position, chemical compositional and topographical data that represent the interaction of the active beam with a point. Position data, chemical compositional data and topographical data are transmitted along individual feeds to a data analysis component where they are analyzed and combined in order to generate a composite image.
