    摘要: Hydrocarbon derivatives are produced by contacting a hydrocarbon with oxygen obtained from an air separation unit in the presence of a partial oxidation reaction catalyst. After separation of the hydrocarbon derivative from the reactor effluent, unreacted hydrocarbon is recovered from the effluent by adsorbing the unreacted hydrocarbon onto an adsorbent at superatmospheric pressure and removing the adsorbed hydrocarbon from the adsorbent by depressurizing said adsorbent and purging the adsorbent with nitrogen obtained from the air separation unit. The recovered unreacted hydrocarbon is recycled to the partial oxidation reactor.

    摘要: A method for blending deuterium-containing gas mixtures used for optical fiber manufacturing and recovering, purifying and recirculating these mixtures. A process is also disclosed for producing optical fiber wherein the optical fiber is treated by soaking the optical fiber with a deuterium-containing gas mixture. The spent or unused deuterium-containing gas is recovered from the chamber containing the optical fiber and purified. This purified deuterium-containing gas is then mixed with fresh deuterium gas and analyzed for purity. If the purity is of sufficient quality, the blend of deuterium gases is directed to a storage tank and onwards to the process chamber containing the optical fiber. Additionally, the purified blend of deuterium-containing gas and fresh deuterium gas can be added directly to the process chamber.

A process is disclosed for producing optical fiber wherein the optical fiber is treated by soaking the optical fiber with a deuterium-containing gas mixture. The spent or unused deuterium-containing gas is recovered from the chamber containing the optical fiber that has been soaked and purified. This purified deuterium-containing gas is then mixed with fresh deuterium gas and analyzed for purity. If the purity is of sufficient quality, the blend of deuterium gases is directed to a storage tank and onwards to the process chamber containing the optical fiber which will be soaked.

    摘要: A process for enriching a crude ammonia stream having moisture and/or metal impurities and/or gas impurities therein. The crude ammonia stream is condensed to form a crude liquid ammonia stream. A distillation membrane or pervaporation membrane is contacted with the crude liquid ammonia stream to form an enriched ammonia vapor stream, which is removed as a permeate. When the crude ammonia stream originates from a manufacturing tool, the enriched ammonia vapor stream may be recycled to the manufacturing tool. There is also an apparatus for enriching a crude ammonia stream.
