Abstract
A process whereby freshwater is generated and wastewater is eliminated through the employ of waste combustion gas; wherein combustion gas is cooled below dewpoint, via the effects of a wastewater fed evaporative cooler, resulting in the combined benefits of freshwater generation from the combustion gas and evaporative reduction of the wastewater.
Claims34
A system for reducing wastewater and generating freshwater comprising:
- a wastewater evaporator;
- a combustion gas contactor;
- a heat exchanger wherein said heat exchanger transfers heat from a combustion gas within said combustion gas contactor to a wastewater within said wastewater evaporator;
- and wherein said heat transfer cools said combustion gas to a temperature below the temperature at which freshwater begins to condense from said combustion gas.
A system for reducing wastewater and generating freshwater comprising:
- a wastewater evaporator;
- a combustion gas contactor;
- a first heat exchanger wherein (i) said first heat exchanger transfers heat from a combustion gas within said combustion gas contactor to a wastewater within said wastewater evaporator and (ii) said heat transfer with said first heat exchanger cools said combustion gas to a temperature above the temperature at which freshwater begins to condense from said combustion gas;
- and
- a second heat exchanger wherein (a) said second heat exchanger further transfers heat from said combustion gas within said combustion gas contactor to said wastewater within said wastewater evaporator and (b) said heat transfer with said second heat exchanger cools said combustion gas to a temperature below the temperature at which freshwater begins to condense from said combustion gas.
A method for reducing wastewater and generating freshwater comprising:
- transferring heat from a combustion gas to a wastewater wherein said transferring cools said combustion gas to a temperature below the temperature at which freshwater begins to condense from said combustion gas and wherein said transferring assists at least partial evaporation of said wastewater.
A method for reducing wastewater and generating freshwater comprising:
- firstly transferring heat from a combustion gas to a wastewater wherein said firstly transferring heat cools said combustion gas to a temperature above the temperature at which freshwater first begins to condense from said combustion gas;
- secondly transferring heat from said combustion gas to said wastewater wherein said secondly transferring heat cools said combustion gas to a temperature below the temperature at which freshwater begins to condense from said combustion gas;
- and evaporating at least a portion of said wastewater with said firstly transferring heat and with said secondly transferring heat.
