SYSTEMS INCLUDING AN APPARATUS COMPRISING BOTH A HUMIDIFICATION REGION AND A DEHUMIDIFICATION REGION

摘要

Embodiments described herein generally relate to apparatuses that include a vessel comprising a humidification region (e.g., a bubble column humidification region) and a dehumidification region (e.g., a bubble column dehumidification region), and associated systems and methods. In certain embodiments, the apparatuses are configured to include various internal features, such as vapor distribution regions and/or liquid flow control weirs and/or baffles. In some cases, the apparatuses are used in water purification systems, such as desalination systems. The water purification systems may comprise additional devices external to the apparatuses, such as one or more heat exchangers, one or more heating devices, and/or one or more cooling devices.

主权项

1. A desalination system, comprising:
a vessel, comprising:
a humidification region comprising a humidification region liquid inlet fluidly connected to a source of salt-containing water, a humidification region gas inlet fluidly connected to a source of a gas, and a humidification region gas outlet, wherein the humidification region is configured to produce a vapor-containing humidification region gas outlet stream enriched in water vapor relative to the gas received from the humidification region gas inlet; anda dehumidification region comprising a dehumidification region gas inlet fluidly connected to the humidification region gas outlet, a dehumidification region gas outlet, and a dehumidification region water outlet, wherein the dehumidification region is configured to remove at least a portion of the water vapor from the vapor-containing humidification region gas outlet stream to produce a dehumidification region water outlet stream and a dehumidification region gas outlet stream lean in water vapor relative to the humidification region gas outlet stream.
