Iran to use heat from power plants to run desalination projects: Minister

Iran’s Energy Minister Reza Ardakanian says massive desalination projects located south of the country would be no longer an environmental concern as they would rely on waste heat collected from power plants as their main source of energy.

Ardakanian said on Tuesday that electricity factories in Iran would provide the energy needed to run major desalination projects along the coast of the Persian Gulf and the Sea of Oman.

Desalination, the process to filter and evaporate sea water, is a very energy-intensive and leads to high levels of pollution because of emissions of greenhouse gases.

However, Ardakanian said Iran’s use of modern technology would boost efficiency and final costs of desalination.

“Supplying energy to a desalination unit through using the exhaust of gas-fired and combined-cycle power plants would both increase efficiency at thermal power plants and help supply drinking water to a bulk of coastline provinces,” he said.

Iran, an arid country facing droughts and shortage of water, is working on two major desalination projects to transfer water from southern seas to provinces located in the Iranian Plateau.

“Surveys are being carried out for supplying water to 17 provinces using saline sea water and through installation of desalination (plants) ...,” Ardakanian told the semi-official Fars news agency.

The minister also added that a second phase of the country’s largest desalination factory, opened two years ago in the southern port city of Bandar Abbas, would come on line within the next few weeks.

“... (this) would ensure supply of more than enough water to Bandar Abbas and surrounding cities,” he said.
