  • Apparatus, use of apparatus and process for desalination of water
    Patent number: 10118836
    Abstract: A process for desalinating water is disclosed. The process comprises the steps of passing a feed stream of saline solution 2? in a first desalination step through a reverse osmosis membrane desalination plant 3? comprising at least one reverse osmosis desalination unit 4? to form a first product water stream 5? having a reduced salt concentration relative to that of the feed stream of saline solution 2? and a first byproduct stream 6? having an increased salt concentration relative to that of the feed stream of saline solution 2? characterized in that the first byproduct stream 6? is passed in a second desalination step through a falling film crystallization unit 7 to form a second product water stream 8 having a reduced salt concentration relative to that of the first byproduct stream 6? and a second byproduct stream 9 having an increased salt concentration relative to that of the first byproduct stream 6?. The invention further relates to an apparatus 1 for carrying out said process.
    Type: Grant

    Date of Patent: November 6, 2018
    Assignee: Sulzer Chemtech AG
    Inventors: Severine Dette, Mansour M. M. Ahmad, Manfred Stepanski
