  • Patent number: 5164076
    Abstract: Processes are disclosed for the separation of hydrogen sulfide from feedstreams containing hydrogen sulfide and hydrocarbons by adsorption using a clinoptilolite adsorbent containing cations having ionic radii of from about 1.10 to 1.40 Angstroms. The processes can provide substantially enhanced adsorption capacities as compared with other adsorbents such as Zeolite 4A. As a result, a throughput of existing sulfur adsorption plants can be increased, e.g., by about 100%. The processes can be operated at elevated adsorption temperatures, e.g., greater than about 200.degree. F., and thus are particularly suitable when integrated with other processing steps such as hydrocarbon conversion reactions that utilize catalysts which are sulfur-sensitive. In addition, the clinoptilolite adsorbents of the present invention have a high tolerance to environments that comprise halides, e.g., HCl.

  • Patent number: 5110903
    Abstract: A process is provided for the preparation of a mixture of parylene dimers wherein the distribution of dimers within the mixture is predetermined by the proper selection of halogenated and non-halogenated 2,2-paracyclophane starting material. Since the dimers are free of alpha-halogens, the formation of environmentally undesirable acid halides during the deposition of parylene films and coatings is avoided. Since the dimers are useful in the preparation of inert, transparent, conformal coatings of parylene, desirable chemical and/or physical properties can be imparted to such coating by formation of a dimer mixture of a predetermined composition. The parylene film properties, composition and deposition conditions will be different by varying dimer distribution.

  • Patent number: 5089034
    Abstract: Processes are disclosed for separating water and carbon dioxide from hydrocarbon streams, e.g., natural gas, by adsorption prior to low temperature hydrocarbon processing operations, e.g., liquid natural gas recovery and nitrogen rejection. The processes employ separate adsorption zones for the water and carbon dioxide adsorption and both adsorption zones are operated with a thermal swing adsorption cycle. A product gas from the low temperature processing operation, e.g., methane, can be used as the purge gas for one or both adsorption zones and the desorbed water and carbon dioxide, along with the purge gas can be recovered and introduced into a natural gas pipeline, for example.

  • Patent number: 5055633
    Abstract: Processes are disclosed for separating by adsorption lower octane normal and mono-methyl paraffins from hydrocarbon feeds containing normal, mono-methyl and more highly branched paraffin fractions in the pentane and hexane carbon range. Adsorbents capable of adsorbing mono-methyl paraffins but not di-methyl branched paraffins are employed to adsorb normal and mono-methyl branched parafins. Isopentane, although adsorbed along with the mono-methyl hexane paraffins, is preferentially adsorbed and eluted from the adsorber bed and recovered as an adsorption effluent along with di-methyl branched hexane paraffin. In one aspect of the invention adsorbents capable of adsorbing normal paraffins but not mono-methyl paraffins are additionally employed to pretreat the feeds to adsorb normal paraffins. Isomerization processes are disclosed for isomerizing the normal and mono-methyl paraffins to produce higher-octane isopentane and more highly branched paraffins.

  • Patent number: 5053058
    Abstract: A process and an apparatus are disclosed for controlling the concentration of a component in an effluent stream from a permeable membrane gas separation system. A gaseous feed stream is passed to the membrane system at a substantially constant flow and elevated pressure. Control is achieved by sensing a characteristic of an effluent stream that is indicative of the concentration of the component, i.e., permeate or non-permeate stream, and performing a pressure adjustment on the permeate stream or non-permeate stream, to vary the concentration of the component in the effluent stream as necessary to obtain a predetermined concentration of the component in the effluent stream. A product stream having a relatively constant pressure and purity can be obtained by sensing a characteristic of a desired effluent stream, e.g., permeate, and performing a pressure adjustment on the other effluent stream, e.g., non-permeate.

  • Patent number: 5042995
    Abstract: A pressure swing adsorption process is provided for the separation of a feedstream containing less readily, intermediately readily, and more readily adsorbable components using first and second adsorption zones. The second adsorption zone utilizes a cycle that includes a cocurrent displacement step and the intermediately adsorbable components are recovered therefrom by countercurrent depressurization. The first adsorption zone is purged with a stream from the second adsorption zone to recover the more readily adsorbable component. In one aspect of the invention, there is provided a methanol reforming process wherein hydrogen and carbon monoxide product streams are recovered from a methanol reactor effluent stream also containing components selected from methanol, methane, dimethyl ether, carbon dioxide, oxygen and water.
