摘要： A method of forming a gas treatment element for use in a gas treatment apparatus, such as a desiccant dryer, is disclosed. The element is formed by casting a sheet material by phase inversion of a dope mixture including a solvent, an adsorbent material such as a desiccant and a polymer binder. Layers of the sheet material are located adjacent one another and this is most readily achieved by rolling the sheet material to form the gas treatment element.
