PROCESS FOR CONTROLLING A DESALINATION PLANT POWERED BY A RENEW ABLE ENERGY SOURCE AND ASSOCIATED PLANT

摘要

The invention relates to a method for controlling a desalination plant of the type comprising one primary seawater supply loop (21, 24, 25, 27) having at least one reverse-osmosis tangential filtration unit (12a, 12b) comprising filtration membranes, one secondary loop (22) having an energy recovery unit (14), and means for supplying (23) power generated by a renewable energy source supplying, according to variable frequencies and power outputs, the pumps of the primary and secondary loops (1, 7, 13), characterized in that the control method includes at least one operating mode in which the pressure and flow rate of the secondary loop (22) are adjusted such that the flow rate of the permeate and the conversion rate change constantly, in parallel and continuously, between a zero value and the maximum value thereof according to the power supplied by the renewable energy source. The invention also relates to the associated plant.
