  • Patent number: 7556055
    Abstract: In one embodiment, the invention provides a rupture disk assembly having a rupture disk and a rupture disk holder. The rupture disk holder has a first annular member downstream of the rupture disk, a second annular member upstream of the rupture disk, and an optional third annular member upstream of the second annular member. An outer peripheral portion of the rupture disk is sandwiched between the first and second annular members; and, if a third annular member is present, (a) the second annular member is sandwiched between the outer peripheral portion of the rupture disk and the third annular member, and (b) the third annular member includes a fluid port aimed at the rupture disk. However, if the third annular member is not present, the second annular member includes a fluid port aimed at the rupture disk.

  • Patent number: 7063827
    Abstract: A conical reactor head for use in chemical processes or other systems is provided. The reactor head includes a robust internal insulator to boost efficiency while maintaining safety by allowing the reactor head to self-radiate at high temperatures. The reactor head also includes a plurality of support lugs to protect its bottom flange from scratches or other damage when the reactor head is set on the ground. The reactor head is adapted to connect to a catalyst-containing barrel which is specially designed to facilitate easy installation and removal of catalysts or other equipment from outside the barrel. The reactor may be coupled with a rotation vane to induce laminar flow at the inlet of the reactor to increase reactor efficiency and prolong catalyst life.
