MEMBRANE AND PROCESS FOR STEAM SEPARATION, PURIFICATION AND RECOVERY

摘要

A process of steam separation using a separation membrane in a separation vessel where the separation membrane separates the vessel into an intake chamber and a recovery chamber. The separation membrane comprises at least one porous support; and a cross-linked hydrophilic polymer membrane material with. an inorganic particulate material or a precursor to an inorganic particulate material. The membrane material is applied to the porous support. The process comprises supplying steam to be purified to the intake chamber of the vessel, the pressure in the intake chamber being greater than the pressure in the recovery chamber; and recovering the purified steam from the recovery chamber of the vessel.
