ELECTRODIALYSIS DEVICE FOR THE DESALINATION OF WATER FOR OIL AND GAS APPLICATIONS
Original language description
The invention relates to an electrodialysis device for the desalination of water for oil and gas applications comprising: a membrane stack comprising alternating cation- and anion-exchange membranes (2.1, 2.3) and; a plurality of spacers (2.2, 2.4), each spacer being arranged between two successive membranes; wherein at least one of the spacers (2.2, 2.4) comprises a recessed area (3.2) and a non-recessed area (3.3), the non-recessed area (3.3) surrounding the recessed area (3.2), and wherein: the spacer (2.2, 2.4) comprises a central opening (3.1) within the recessed area (3.2); the spacer (2.2, 2.4) is provided with at least four orifices (3.4, 3.5) within the non-recessed area (3.3); the spacer (2.2, 2.4) is provided with respective channels (3.6) which connect at least two of the orifices (3.4) with the central opening (3.1); and one cation-exchange or anion-exchange membrane (2.1, 2.3) is accommodated in the recessed area (3.2). The invention also relates to a water desalination process using the electrodialysis device mentioned above, a process for extracting hydrocarbons from a subterranean formation, as well as a process for the desalination of water performed at a temperature from 35 to 80°C
