ABSTRACT LIQUID-VAPOR CONTACT COLUMNS A packing for a liquid-vapor contact column is provided which comprises metallic sheets defining liquid-vapor passages and having at least one wettable surface comprised of a coating of porous metal. The sheets are perforated to permit vapor to pass between them. The porous metal coating is formed by spraying a particulate mixture of metal and a plastics material onto the sheet to form a coating of plastics particles embedded in metal and then heating to volatilize the plastic thereby forming porosity in the metal coating.
