LIQUID DESICCANT REGENERATION SYSTEM, SYSTEMS INCLUDING THE SAME, AND METHODS OF OPERATING THE SAME

摘要

A liquid desiccant regeneration system and method of liquid desiccant regeneration are described. The liquid desiccant regeneration system includes a liquid desiccant regenerator having an engine producing a heated exit stream, and at least one dehydrating tube comprising a first water vapor permeable wall. A low concentration liquid desiccant stream feeds into the liquid desiccant regenerator, while a high concentration liquid desiccant stream exiting the liquid desiccant regenerator. A carrier stream and the low concentration liquid desiccant are in contact with opposite sides of the first water vapor permeable wall, and the low concentration liquid desiccant stream is heated by heat from the heated exit stream to drive water from the low concentration liquid desiccant stream through the first water vapor permeable wall to the carrier stream to form a humidified carrier stream. As a result, the desiccant concentration in the high concentration liquid desiccant stream is higher than a desiccant concentration in the low concentration liquid desiccant stream.

1. A liquid desiccant regeneration system, comprising:
a liquid desiccant regenerator comprising
an engine producing a heated exit stream, andat least one dehydrating tube comprising a first water vapor permeable wall; a low concentration liquid desiccant stream feeding into said liquid desiccant regenerator; and a high concentration liquid desiccant stream exiting said liquid desiccant regenerator, wherein a carrier stream and the low concentration liquid desiccant are in contact with opposite sides of said first water vapor permeable wall, wherein the low concentration liquid desiccant stream is heated by heat from the heated exit stream to drive water from the low concentration liquid desiccant stream through the first water vapor permeable wall to the carrier stream to form a humidified carrier stream, wherein a desiccant concentration in said high concentration liquid desiccant stream is higher than a desiccant concentration in said low concentration liquid desiccant stream.
