Abstract: In various embodiments, the present invention relates to heat dissipation systems including a hygroscopic working fluid and methods of using the same. In various embodiments, the present invention provides a method for heat dissipation using a hygroscopic working fluid. The method can include transferring thermal energy from a heated process fluid to the hygroscopic working fluid in a process heat exchanger, to form a cooled process fluid. The method can include condensing liquid from a feed gas on a heat transfer surface of a feed gas heat exchanger in contact with the cooled process fluid, to form a cooled feed gas, the heated process fluid, and a condensate. The method can include dissipating thermal energy from the hygroscopic working fluid to a cooling gas composition with a fluid-air contactor. The method can include transferring moisture between the hygroscopic working fluid and the cooling gas composition with the fluid-air contactor. The method can include adding at least part of the condensate to the hygroscopic working fluid.

Abstract: Chilled seawater formed through interaction with a liquefied gas vaporizer may facilitate various types of heat exchange processes. The extent to which the seawater may be cooled is often limited by local environmental regulations for discharging the seawater once heat exchange has taken place. The foregoing issues may be addressed by systems comprising a liquefied gas vaporizer; a supply line configured to distribute seawater upon the liquefied gas vaporizer; a collection reservoir below the liquefied gas vaporizer configured to gather chilled seawater passing therethrough; a heat exchanger in fluid communication with the collection reservoir; and a heat exchanger outlet line configured to discharge heat-exchanged seawater to a sea location. The heat exchanger may be in direct or indirect thermal communication with a flow pathway for air provided to a gas engine or gas turbine, which may alter speed, power or efficiency of the gas engine or gas turbine.
