An improved process for recovery of CO.sub.2 gas in a raw material mixed gas by a PSA apparatus. The process is characterized in that the removal of water in the raw material mixed gas is carried out by cooling the raw material mixed gas and passing it through a rotary dehumidification apparatus to remove water in the raw material mixed gas, and the regeneration of the rotary dehumidification apparatus is carried out by using as a gas for regeneration unadsorbed gas discharged from an adsorption step in the PSA apparatus with heating.

Process for removal of water in raw material mixed gas

This invention relates to a method of producing a corrosion-, heat- and wear-resistant member which comprises packing an atomized powder of a high-carbon high-chromium steel into a capsule, heating the capsule packed with the powder, then extruding the capsule packed with the powder to obtain a stock not containing carbide grains greater than 3 .mu.m, working the stock, polishing a surface of the stock, and evaporating a film of TiC and/or TiN onto the polished surface, and further a corrosion-, heat- and wear-resistant member produced by the method. The corrosion-, heat- and wear-resistant member according to this invention is suitable for being members for tools used under extremely severe conditions, such as various tools for can manufacturing, molding tools for reinforced plastics, etc.
