Analysis of technical feasibility to directly use mechanical energy coming from a wind generator to power pumps installation of seawater desalination.
|KEYWORDS||Seawater Desalination; ?Water consumption|
|KEYWORDS TYPE||Designing a pilot installation exploit wind energy|
|MARKET NEED TAILORED|
Problems in the water supply in coastal zones.
High energy consumption in desalination plants.
Water supply with shortages;Subprogramme INNPACTO.
The fundamental objective of the subprogramme INNPACTO is promoting the creation of cooperative projects between research organizations and companies for the joint execution of I+D+i to help boost innovative activity, mobilize private investment, create jobs and improve the technological balance of the country.
Use the mechanical energy of wind power plants directly to power pumps installation of seawater desalination by reverse osmosis and also harness energy from the reject brine to produce electricity through the turbine shaft pelton, something new in desalination technologies.
|STATE OF DEVELOPMENT|
The study aims to face two basic problems common at desalination plants, which are the high energy consumption and pollution from the dumping of brine rejection into the sea.
|INNOVATIVE ASPECTS AND ADVANTAGES|
The shape of the energy supply for the facility proposed in this study is novel, instead of running through the power of the wind turbine generator, to use the mechanical energy produced by its blades without the conversion from this to power.
Another new technology introduced by this project includes also a form of energy recovery using pressure which is brine rejection to power a turbine and generate electricity Pelton.
With this process proposed by the wind energy produced is stored in the form of drinking water, disposal quick and easy storage. The potable water production, therefore, involves no electric power consumption.
|INTELLECTUAL/INDUSTRIAL PROPERTY RIGHTS|
The project has a previous patent owned by GASA: PCT/ES2007/000731
Be implemented in coastal areas of Spain where there is a shortage of potable water provision.
The process will be energetically autonomous
Coastal areas of Spain and the Mediterranean seacoast
|Estimation of risks|
|EVALUATION OF RISKS FOR OUTPUT USERS|
Shortage of flow and water quality for human consumption.
|ECONOMICAL RISKS||Reverse osmosis, compared to other methods, has many advantages from the point of view of implementation, initial investment, consumption both thermal and electrical energy, which in this case are hardly visible values, maintaining that the project is red|
|MARKET RISKS||Only has developed a small scale prototype.|
|NEXT STEPS TO ACHIEVE THE STATUS 'READY TO USE'|
Studying the operating conditions of the installation and optimize the various operating parameters
|TYPE OF PARTNER FOR THE NEXT DEVELOPMENTS||Engineering companies, public authorities (national governments), research centres|
|TASKS TO BE PERFORMED|
Major scientific research and testing on large scales for more specific results and encourage governments made significant investments to develop.
