A method for processing flue-gas, in an exemplary embodiment, includes providing an absorber unit having a membrane contactor, channeling a combustion flue gas along a first surface of the membrane contactor, and channeling an ammonia-based liquid reagent along a second opposing surface of the membrane contactor. The method also includes partially separating the ammonia-based liquid from the flue gas such that the ammonia-based liquid and the flue gas contact at gas-liquid interface areas, defined by a plurality of pores of the membrane contactor, to separate COfrom the flue gas by a chemical absorption of COwithin the ammonia-based liquid to produce a CO-rich ammonia-based liquid.

A system and method of predicting telemetry signal dropout creates a prediction of patient destination. The method includes defining a telemetry coverage area, receiving a location of a monitored patient, recording the received location, calculating a trajectory and speed, and comparing the location, trajectory, and speed of the patient to historical patient movement trends to predict patient destination. The system includes a remote unit worn by a patient and at least one telemetry receiver, a location services computer, a patient location database, a location prediction computer, and a graphical display. The location services computer receives the location information and computes a location, speed, and trajectory of the patient. The location prediction computer compares the computed location, speed, and trajectory of the patient to previously acquired locations, speeds, and trajectories to predict a patient destination.

A method to facilitate improving electrostatic precipitator performance is provided. The method includes providing an electrostatic precipitator including an inlet, a collector chamber and an outlet, where the collector chamber includes a plurality of discharge electrodes and a plurality of collector electrodes. The method also includes defining a respective discharge electrode V-I performance for each of the plurality of discharge electrodes, identifying a particle removal characteristic for each respective discharge electrode based on the respective discharge electrode V-I performance for each of the plurality of discharge electrodes and positioning each of the plurality of discharge electrodes in the electrostatic precipitator according to the particle removal characteristic for each respective discharge electrode.

An apparatus for cleaning a continuous emissions monitor system that is in fluid communication with a flue stack conducting exhaust gas from a combustion source. The apparatus comprises a housing and a probe mounted in the housing. The probe is tubular and in fluid communication with the flue stack to acquire a sample of gas from the flue stack. The probe tends to have deposits from the exhaust gas accumulate on the inner walls of the probe. A device imparts cleaning energy to the probe for dislodging accumulated deposits from the inner walls of the probe.
