Pulsed Absorption Contactor Dynamics

The patent applies dynamics by transforming the static packing surface into a dynamic, moving surface through the introduction of a pulsating liquid film. The liquid film oscillates back and forth across the packing elements, creating continuous renewal of the gas-liquid interface while maintaining extended contact time. This dynamic approach allows the system to achieve both large effective surface area and prolonged interaction between gas and liquid phases.

The patent implements periodic action through the pulsating liquid film mechanism that oscillates at controlled frequencies. The periodic pulsation creates repeated cycles of liquid film formation, breakdown, and reformation across the packing surface, which enhances mass transfer by continuously exposing fresh liquid surfaces to the gas phase while maintaining extended contact duration through the oscillatory motion.

The patent resolves this contradiction by introducing dynamic pulsation to the liquid flow while maintaining the counter-flow arrangement. The pulsating liquid film creates periodic reversal of flow direction, which allows the system to benefit from the high concentration gradient of counter-flow while also achieving extended contact duration through the oscillatory motion that repeatedly brings gas and liquid into contact.

The periodic pulsation superimposed on the counter-flow arrangement creates cycles of forward and reverse liquid flow. During each cycle, the liquid film advances across the packing surface creating strong concentration gradient-driven mass transfer, then reverses direction maintaining contact with the gas phase, thereby achieving both high driving force and extended contact duration through the periodic oscillation.

The patent applies dynamics by using a pulsating liquid film that continuously moves and renews across the packing surface. This dynamic motion prevents contaminants from settling and accumulating on the packing elements by constantly disrupting potential deposition sites, thereby maintaining high absorption capacity over extended periods without the contaminant buildup issues associated with static large-surface-area designs.

The continuous pulsation of the liquid film ensures uninterrupted cleaning action across the packing surface. The perpetual oscillatory motion maintains a fresh liquid interface that prevents contaminant accumulation, allowing the system to sustain high absorption capacity continuously without the degradation that would occur in static systems where contaminants gradually build up on the large surface area.
