Abstract: Parametric characterization of nitric oxide (NO) gas exchange using a two-compartment model of the lungs is a non-invasive technique to characterize inflammatory lung diseases. The technique applies the two-compartment model to parametric characterization of NO gas exchange from a tidal breathing pattern. The model is used to estimate up to six flow-independent parameters, and to study alternate breathing patterns.

Abstract: An apparatus and method to characterize NO gas exchange dynamics in human lungs comprising the steps of: (1) performing a series of breath hold maneuvers of progressively increasingly breath hold times, each breath hold maneuver comprising a) inhaling a gas, b) holding a breath for a selected time duration, and c) exhaling at a flow rate which is uncontrolled but which is effective to ensure evacuation of the airway space and (2) measuring airway NO parameters during consecutive breath hold maneuvers. As a result disease states of the lungs are diagnosed using the measured airway NO parameters.

Abstract: An apparatus and method to characterize NO gas exchange dynamics in human lungs, including performing a plurality of breathing maneuvers of substantially constant flow rates within a predetermined range, measuring data relating to at least one of an NO concentration and an NO elimination rate as a function of exhaled volume or exhalation flow rate, applying a lung model to the measured data, and obtaining at least one parameter indicative of disease states of the lung based on the lung model and the measured data, wherein the lung model, when applied in the predetermined range, predicts a substantially linear relationship between the NO elimination rate and the exhalation flow rate.

Abstract: A recovery plant for recovery of a gaseous component from a process gas has an absorber employing a lean solvent and a semi-lean solvent that absorb the gaseous component from the process gas, thereby producing a rich solvent, a semi-rich solvent, and a lean process gas. A regenerator extracts the gaseous component from the rich solvent, thereby regenerating the lean solvent and the semi-lean solvent. A solvent flow control element combines at least part of the semi-rich solvent and the semi-lean solvent to form a mixed solvent, and a cooler cools the mixed solvent that is subsequently fed into the absorber. In a method of removing a gaseous component from a process gas, a stream of lean solvent and a stream of semi-lean solvent are provided. In another step, the stream of lean solvent and the stream of semi-lean solvent contact the process gas in an absorber to produce a stream of semi-rich solvent and rich solvent.

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.
