Systems including a condensing apparatus such as a bubble column condenser

The patent employs a bubble column condenser where vapor and non-condensable gases are introduced as bubbles into a liquid column. This pneumatic approach allows the vapor to come into direct contact with the liquid phase, enabling efficient mass transfer and condensation even in the presence of non-condensable gases. The bubbling action creates large interfacial area between vapor and liquid, dramatically improving heat and mass transfer rates compared to conventional surface condensers.

The invention changes the physical state and phase distribution parameters by introducing the vapor mixture into the liquid phase rather than condensing on a cold surface. By transforming the condensation process from surface-based to bulk liquid-based, the system achieves improved transfer rates. The liquid column acts as both the condensing medium and the heat transfer medium, fundamentally changing the operational parameters of the condensation process.

The bubble column design uses the liquid phase to absorb both the condensable vapor and the non-condensable gases simultaneously. The vigorous mixing and large interfacial area created by bubbling ensure that non-condensable gases do not form insulating layers on condensation surfaces, thereby minimizing thermal resistance. The system handles gas mixtures efficiently by design rather than by exclusion.

The liquid column serves as an intermediary medium that facilitates heat and mass transfer between the vapor phase and the condensation process. Instead of vapor condensing directly on a cold surface where non-condensable gases would create thermal resistance, the liquid acts as an intermediate carrier that absorbs heat and vapor simultaneously, bypassing the thermal resistance issue.

The bubble column condenser is designed to utilize the inherent energy of the incoming vapor stream to drive the condensation process. The vapor itself provides the driving force for bubbling and mixing, and the liquid column is cooled by the process conditions rather than requiring external high-energy cooling systems. The system achieves condensation with minimal external energy input by leveraging the thermodynamic properties of the process streams.

The invention changes the energy utilization parameters by operating in a regime where mass transfer and heat transfer occur simultaneously in the liquid phase. This eliminates the need for high-energy external cooling systems required by conventional surface condensers, as the liquid column naturally accepts the latent heat of condensation and the non-condensable gases are handled without additional energy input.
