| 摘要 |
The present invention concerns a method and an arrangement for dehumidifying and desalting interior air in off-shore installations. A simplified arrangement is presented wherein exterior intake air containing water rich in supersaturated and wet salt particles is pretreated with dry and salt free pretreatment air before entering a dehumidifying and de-salting unit from which the intake air exits as desalted and dehumidified exit air. A part of this desalted and dehumidified exit air is then redirected to the intake air flow path to serve as pretreatment air thereby simplifying construction and enhancing the lifetime of the dehumidifying and desalting unit. |
