Abstract
Devices, systems, and methods for cooling a gas is disclosed. A slurry is passed through a droplet generating device to produce droplets of the slurry. The slurry comprises a contact liquid and solids. A melting point of the solids is higher than a vaporization point of the contact liquid. A carrier gas is passed across the droplets to exchange heat between the carrier gas and the droplets. At least a portion of the heat transferred to the droplets melts the solids.
Claims15
A method for cooling a gas comprising:
- passing a slurry through a droplet generating device to produce droplets of the slurry, wherein the slurry comprises a contact liquid and solids, and wherein a melting point of the solids is higher than a vaporization point of the contact liquid;
- passing a carrier gas across the droplets to exchange heat between the carrier gas and the droplets, wherein at least a portion of the heat transferred to the droplets melts the solids;
- and
- wherein the droplet generating device comprises a drip tray, spray nozzles, a protrusion droplet generator, capillary tubes, or combinations thereof, the droplet generating device is installed in a direct-contact exchanger, the direct-contact exchanger comprises a counter-current, a co-current, or a cross-current flow relative to the droplets, and the contact liquid and melted solids are cooled through a heat exchanger, freezing the melted solids and forming the slurry.
