| titleOfInvention | Method, composition and apparatus for removing water from a non-corrosive gas stream |
| abstract | PROBLEM TO BE SOLVED: To remove water from a mainstream used in the production of semiconductors, drugs, optical fibers and products which dislike water in production. The present invention relates to a method for removing water from a wet non-corrosive gas (for example, one containing oxygen or CO 2 ). Methods, compositions and equipment for removing water concentrations of ２０20 ppb. According to the invention, the dehydrating agent is an oxide or salt of a positive metal, at least 140 m 2 / g, preferably 140-500 m 2 / g, and is compatible with gases, preferably such gases can be dehydrated to as low as 1 ppb, more preferably as low as 500 ppt. Positive metals are Group 3b, It may be a Group 4b or lanthanide metal or vanadium. Preferred dehydrating agents are high surface area titania, zirconia, yttria or vanadia, with titania being particularly preferred. The dehydrating agent may be in the form of a pelletized or fine-grained bulk material or a coating on the support or within the pores of the support. |
