A system for generating electricity, heat, and desalinated water having a gas turbine system connected to a first electric generator, a waste heat recovery boiler (WHRB) system, a combined heat and power (CHP) generation system connected to a second electric generator, one or more solar powered energy systems, and a desalination system. The desalination system is connected to the CHP generation system and the WHRB system. The gas turbine system generates electricity and heat, the WHRB system is connected to and uses the exhaust of the gas turbine system to provide heat and steam power to the CHP generation system. The CHP generation system produces and provides electricity and heat to the desalination system, which produces product water, and at least one solar powered energy system provides thermal energy to one or more of the gas turbine system, the WHRB system, the CHP generation system, and the desalination system.

This disclosure provides a system for coupling supercritical carbon dioxide cycle power generation and lithium extraction from brine. The system comprises an absorption heat pump unit, a supercritical carbon dioxide cycle power generation unit, and a unit for extracting lithium from brine. This system organically couples the exothermic characteristics of the supercritical carbon dioxide cycle system with the endothermic characteristics of the lithium extraction from brine system, and the waste heat is recycled in a cascade as the heat source in the lithium extraction from brine system, thereby effectively reducing the total energy consumption of power generation and lithium extraction and reduce the total equipment investment of the system, and significantly improving the efficiency of adsorption and lithium precipitation in the lithium extraction from brine system.

A method may include providing a humidification-dehumidification unit proximate one or more abandoned wells, circulating a water feed through the one or more abandoned wells, using geothermal heat in the one or more abandoned wells to heat the water feed, directing the heated water feed to the humidification-dehumidification unit, and treating the heated water feed in the humidification-dehumidification unit to provide purified water.

A multi-stage flash reversal unit includes a housing; plural stages located inside the housing; an evaporation port that receives a water feed having a first temperature; a condensation port that outputs a concentrated water feed having a second temperature, which is lower than the first temperature; and a cooling unit that cools down the concentrated water feed.

Evaporator system used for the production of maple syrup. The evaporator system includes at least one receptacle, a combustion chamber, an evacuation port and an air supply system. The evaporator system also includes a door assembly being configured for removably mounting onto a corresponding support frame of the evaporator system, and being operable between an opened configuration for allowing access to the combustion chamber and to be able to selectively feed biomass into the combustion chamber via the inlet thereof, and a closed configuration for preventing access to and closing off the inlet of the combustion chamber, the door assembly being provided with at least one aeration passage extending between an outer portion of the door assembly and an inner portion therefor, for providing a supply of secondary air to the combustion chamber via said at least one aeration passage of the door assembly when operated in the closed configuration.

The invention relates to a system and device for desalination by liquid water jet compression, which is a phase-change desalination with a high-efficiency latent heat exchanger in which the pressure of the primary saturated vapor is increased until obtaining the secondary saturated vapor by injecting translational and rotational kinetic energy via pressurized water jets, so as to leave an unobstructed path through which the vapor flows at high speed in order to achieve a high flow rate and high efficiency.

A mechanical vapor recompression evaporation system wherein a fluid stream from a fluid source is compressed in a compressor and used to transfer heat to an incoming stream of liquid, the system comprising a combustion engine mechanically coupled to the compressor to drive the compressor, and having a combustion exhaust gas conduit; and a mixing chamber or heat exchanger in fluid communication with the combustion exhaust gas conduit and the fluid to transfer heat from the hot exhaust gas to the fluid stream.

A system for processing saltwater or brackish water while recovering energy otherwise wasted in electricity generation by a natural gas generator or turbine. Heat in the generator exhaust is used to directly heat and process the water in the saltwater or brackish water into high quality steam, separating the majority of salt and contaminants from the water, and leaving potable water that can be permitted and released to the environment or sold for agricultural or industrial use such as oilfield activities. The system also captures and liquefies CO.sub.2 in the generator exhaust.

Method of concentrating aqueous alkali and apparatus suitable for this purpose. A very energy-saving method of concentrating aqueous alkali originating, for example, from a chloralkali electrolysis plant and an apparatus suitable for this purpose are described. The method/the apparatus utilizes heat of reaction from the formation of 1,2-dichloroethane and includes multistage concentration of the aqueous alkali, where at least part of the heat required for concentrating the aqueous alkali originates from the plant for preparing 1,2-dichloroethane and at least a further part of the heat required for concentrating the aqueous alkali originates from at least one of the higher stages of the plant for concentrating the aqueous alkali and is used for partial heating of the first stage. The apparatus can be used for retrofitting existing integrated plants made up of a DCE plant and chloralkali electrolysis or in the erection of new plants.

A desalination system that can comprise an inlet, an optional preheating stage, multiple evaporation chambers and optional demisters, product condensers, a waste outlet, one or more product outlets, a nested configuration that facilitates heat transfer and recovery and a control system. The control system can permit operation of the purification system continuously with minimal user intervention or cleaning. The desalination system can operate with any number of pre-treatment methods for descaling, and with degassing systems to eliminate or reduce hydrocarbons and dissolved gases. The system is capable of removing, from a contaminated water sample, a plurality of contaminant types including microbiological contaminants, radiological contaminants, metals, and salts.
