  • Patent number: 8974675
    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.

  • Publication number: 20140296607
    Abstract: A process for removing halogen compounds, particularly chlorine compounds, from a process fluid, includes the steps of (i) passing a process fluid containing hydrogen halide over a first sorbent to remove hydrogen halide and generate a hydrogen halide depleted process fluid and then, (ii) passing the hydrogen halide depleted process fluid over a second different sorbent to remove organic halide compounds therefrom. A purification system suitable for removing hydrogen halide and organic halide compounds from process fluids is also described.

  • Publication number: 20140263067
    Abstract: A distributor plate for a resin tank of a fluid treatment device such as a water softener includes a central hub, an outer ring, a plurality of ribs extending between the hub and the ring and dividing the distributor plate into discrete segments, and a slotted plate connected therebetween. The distributor plate separates the resin bed from a lower end of the resin tank. The distributor plate further comprises at least one valve plate coupled to an underside of the distributor plate over at least one segment thereof. The valve plate is constructed from a material configured to float in the fluid being treated and is movable between a raised position during upflow and a lowered position during downflow. In this manner, the valve plate acts like a check valve to regulate the manner in which fluid flows through the distributor plate during upflow and downflow, improving resin scrubbing during upflow.
