US 12,320,101 B2 · Water recovery system including integrated contactor with thermally-enhanced recovery

Abstract

A water recovery system including a first fluid stream inlet providing for the flow of a first fluid stream, such as a humidified inlet gas, into the system and a second fluid stream inlet providing for the flow of a second fluid stream, such as a gas having a temperature greater than the humidified inlet gas, into the system. At least one contactor is in fluid communication with the first fluid stream inlet and the second fluid stream inlet. The at least one contactor defining therein a first fluidically-isolated, sorbent-integrated, fluid domain for flow of the first fluid stream and water adsorption, a second fluidically-isolated fluid domain for flow of the second fluid stream wherein the second fluidically-isolated fluid domain is in thermal communication with the first fluidically-isolated, sorbent-integrated, fluid domain and a third fluidically-isolated fluid domain for capture of a condensate and recycling of latent heat of condensation back to the first fluidically-isolated, sorbent-integrated, fluid domain.

Dependent claims

A water recovery system comprising:

a humid gas inlet configured to enable a humid gas to flow into the water recovery system and a thermal fluid inlet configured to enable a thermal fluid to flow into the water recovery system;
and
at least one contactor in fluid communication with the humid gas inlet and the thermal fluid inlet, the at least one contactor comprising:
a sorbent flow path configured to receive the humid gas and adsorb water from the humid gas into a sorbent material;
a thermal flow path configured to receive the thermal fluid, wherein the thermal flow path is configured to transfer heat between the thermal fluid and the sorbent material;
and
a condenser flow path configured to capture a condensate, wherein the condenser flow path is configured to transfer latent heat of condensation to the sorbent material.
