    Abstract: Sulfur contaminants, such as elemental sulfur (S8), hydrogen sulfide and other sulfur components in fluids (e.g., air, natural gas, and other gases, as well as water and other liquids) are removed using a silicone-based chemical filter/bath. In one embodiment, a silicone-based chemical filter includes a membrane having a cross-linked silicone that is a reaction product of an olefin and a polyhydrosiloxane. For example, sulfur contaminants in air may be removed by passing the air through the membrane before the air enters a data center or other facility housing computer systems. In another embodiment, a silicone-based chemical bath includes a housing having an inlet port, an outlet port, and a chamber containing a silicone oil. For example, sulfur contaminants in air may be removed by passing the air through the silicone oil in the chamber before the air enters a data center or other facility housing computer systems.

  • Patent number: 8568512
    Abstract: The method and system for methane separation and purification from a biogas includes collecting a raw Biogas gas stream having methane, carbon dioxide, water, sulfur compounds and non-methane organic compound (NMOC) constituents. The Biogas stream is fed into the intake of a liquid sulfur scrubber or a sulfur adsorber unit where the Biogas is separated into a main gas stream routed downstream in the system and a sulfur compounds stream removed from the system. The main gas stream is then processed by an NMOC absorber and further downstream, by an NMOC adsorber. NMOC produced by both NMOC processes is liquefied, removed from the system and stored. Upstream from the NMOC processes, the main gas stream is processed by at least one CO2, N2, O2 gas separation unit that produces a usable product stream of enriched methane gas, and an off-gas stream, which a VPSAU processes for venting and recycling.

    Abstract: Effective synthesis gas purification is achieved by applying copper adsorbents which are resistant to the reduction by the components of the synthesis gas H2 and CO at normal operation conditions. The novel adsorbents are produced by admixing small amounts of an inorganic halide, such as NaCl, to the basic copper carbonate precursor followed by calcination at a temperature sufficient to decompose the carbonate. The introduction of the halide can be also achieved during the forming stage of adsorbent preparation. These reduction resistant copper oxides can be in the form of composites with alumina and are especially useful for purification of synthesis gas or gas streams containing hydrogen carbon monoxide or other reducing agents.

Active desorbing of volatiles can be carried out with forced thermal desorption, where the interior surfaces of the building are heated while the air is removed and replaced with air free of the volatile compounds. The absorbent for passive desorption can be a nanoparticulate metal oxide.

  • Patent number: 8323603
    Abstract: A method for producing a substantially desulfurized a hydrocarbon fuel stream at temperatures less than 100° C. The method includes providing a nondesulfurized fuel cell hydrocarbon fuel stream that may include water and passing the fuel stream sequentially through a zeolite Y adsorbent and a selective sulfur adsorbent. The zeolite Y adsorbent may be exchanged with copper ions. The method produces a substantially desulfurized hydrocarbon fuel stream containing less than 50 ppb sulfur.

  • Patent number: 8317902
    Abstract: A process for removing polar components from a process stream in a refinery process without cooling the process stream. The process stream is fed to a first adsorber unit to remove contaminants containing sulfur at substantially the same elevated temperature by exposing the process stream to a metal oxide and/or a mixed metal oxide to remove the sulfur containing contaminants and produce a metal sulfide and a desulfurized process stream. The metal sulfide may be regenerated by exposing it to a stream of oxygen and the desulfurized process stream exposed to the regenerated metal/mixed metal oxide to remove moisture from the stream. The stream is then processed within a second adsorber unit to remove nitrogen containing contaminants at substantially the same elevated temperature by exposing the stream to a molecular sieve and/or zeolite.

  • Patent number: 8293133
    Abstract: Crystals of [VOBDC](H2BDC)0.71 were synthesized hydrothemally. The guest acid molecules were removed by heating in air to give high quality single crystals of VOBDC. VOBDC was observed to show crystal-to-crystal transformations on absorption of the guest molecules aniline, thiophene and acetone from the liquid phase. Accurate structural data of the guest molecules and framework deformations were obtained from single crystal X-ray data. VOBDC was also shown to absorb selectively thiophene and dimethyl sulphide from methane.
