Systems including a condensing apparatus such as a bubble column condenser

The patent applies pneumatic principles by using gas bubbles (air-water mixture) as the condensing medium instead of liquid water or metallic surfaces. The vapor-containing gas stream is contacted with cold gas bubbles in a bubble column, where condensation occurs on the bubble surfaces. This pneumatic approach eliminates the thermal resistance problem associated with non-condensable gases on solid surfaces, as the bubbles provide a fluid interface that maintains high heat and mass transfer rates even in the presence of non-condensable gases.

The bubble column condenser uses pneumatic principles to create gas bubbles that serve as the condensing surface. These bubbles have high surface area to volume ratio and are constantly renewing, providing excellent heat and mass transfer characteristics. The system requires less energy input because the pneumatic bubble-based condensation process is more efficient than traditional surface condensers, particularly in handling vapor streams containing non-condensable gases.

The invention replaces metallic solid surfaces with pneumatic gas bubbles as the condensing medium. The gas bubbles provide a fluid interface that eliminates the thermal resistance barrier created by non-condensable gases accumulating on solid surfaces. The continuous formation and rupture of bubbles ensures fresh contact surfaces, maintaining high condensation effectiveness without the thermal resistance problems of traditional metallic condensers.
