Abstract: Methods and systems for estimating remaining or utilized scrubbing capacity of a gas scrubber are described. Inside the gas scrubber, a reaction gas is produced by an exothermic or endothermic reaction. Temperature sensors are positioned along the gas flow path, and temperature readings are obtained. Temperature differences between pairs of adjacent temperature sensors are determined. The largest temperature difference for each such pair is recorded. A recent temperature difference is normalized by dividing the recent difference by the largest recorded for the same pair. One or more of the normalized temperature differences may be weighted. The normalized temperature differences and/or the weighted temperature differences are combined to provide a life-value, which is indicative of the remaining or utilized scrubbing capacity of the gas scrubber.

Abstract: A method and system are provided for estimating remaining absorptive capacity of a gas absorber. Inside the gas absorber, a reaction gas is produced by an exothermic or endothermic reaction. A plurality of temperature sensors include a first temperature sensor positioned at the gas absorber's inlet and subsequent temperature sensors spaced apart along the gas's flow path therethrough. Temperature differences between each subsequent temperature sensor and the first temperature sensor are determined. Each temperature difference is normalized using the largest one of the temperature differences so that corresponding normalized temperature differences are generated. The normalized temperatures differences are indicative of the remaining absorptive capacity of the gas absorber in accordance with a selected, experimentally-determined calibration function.
