Method and plant for joint production of electricity, steam and desalinated water

摘要

The process for joint production of electricity, vapor and desalinated water, comprises producing vapor using a unit (2), passing the vapor to a turbine (3) to produce electricity and vapor, evaporating sea water to produce the desalinated water by exchange of heat with the vapor, and controlling a quantity of vapor required to the turbine according to a demand of electricity, desalinized water and vapor. A part of vapor produced by the unit is mixed with the vapor produced by the turbine. The vapor produced by the turbine becomes a condensate. The process for joint production of electricity, vapor and desalinated water, comprises producing vapor using a unit (2), passing the vapor to a turbine (3) to produce electricity and vapor, evaporating sea water to produce the desalinated water by exchange of heat with the vapor, and controlling a quantity of vapor required to the turbine according to a demand of electricity, desalinized water and vapor. A part of vapor produced by the unit is mixed with the vapor produced by the turbine. The vapor produced by the turbine becomes a condensate, which is used as a complement source in water by the vapor production unit. A gas turbine (1) is used to produce a part of electricity and an exhaust gas (5) is used to produce the vapor. The desalinated water is produced by a reverse osmosis technology using the electricity produced by the turbine. An independent claim is included for a machine for producing electricity, vapor and desalinated water.
