Abstract
Systems and methods for producing water from process gas are provided herein. The systems include a water generating system that adjusts the pressure and temperature conditions surrounding a hygroscopic material in order to release water vapor generated by exposure of the hygroscopic material to the process gas.
Claims30
A system for producing liquid water from a process gas, the system comprising:
- a sealable housing defining an interior volume, the sealable housing comprising a process gas inlet configured to input the process gas into the interior volume during a load time;
- a hygroscopic material retained within the interior volume, wherein the hygroscopic material is configured to capture water vapor from the process gas during the load time, and wherein the hygroscopic material is configured to absorb thermal energy during a release time;
- and
- a means for producing a reduced pressure condition within the interior volume during the release time, wherein the reduced pressure condition is characterized by reduction of a partial pressure of water vapor within the interior volume to below a vapor pressure of water captured by the hygroscopic material during the load time;
- wherein the means for producing the reduced pressure condition comprises the process gas inlet, and wherein the process gas inlet is configured to leak a carrier gas into the interior volume during the release time.

A method for producing liquid water from a process gas comprising:
- inputting the process gas through a process gas inlet into an interior volume defined by a sealable housing during a load time, wherein a hygroscopic material retained within the interior volume is configured to capture water vapor from the process gas during the load time;
- forming a reduced pressure condition within the interior volume during a release time by increasing a ratio of vapor pressure of water captured by the hygroscopic material to water vapor partial pressure in the interior volume;
- wherein the forming of the reduced pressure condition comprises inputting a carrier gas into the interior volume during the release time;
- and
- wherein the carrier gas is leaked into the sealable housing via the process gas inlet;
- exposing the hygroscopic material to a thermal energy source during the release time, wherein the hygroscopic material is configured to absorb thermal energy during the release time;
- and
- communicating a water vapor output from the interior volume during the release time.

A system comprising:
- a sealable housing defining an interior volume, the sealable housing comprising a process gas inlet configured to input the process gas into the interior volume during a load time;
- and
- a hygroscopic material retained within the interior volume, wherein the hygroscopic material is configured to capture water vapor from the process gas during the load time, and wherein the hygroscopic material is configured to absorb thermal energy during a release time, and,
- wherein the carrier gas is leaked into the sealable housing via the process gas inlet;
- wherein the sealable housing is configured to enable for a reduced pressure condition within the interior volume during the release time, and
- wherein the reduced pressure condition is characterized by reduction of a partial pressure of water vapor within the interior volume to below a vapor pressure of water captured by the hygroscopic material during the load time.
