Abstract: A mechanism for selectively securing a cover to a flange of a pressure vessel. The cover and flange each have openings that are aligned when the cover is in position facing the flange. The mechanism includes an anchor plate having a hole therethrough. A piston is slidable in a direction normal to the cover in alignment with the opening therethrough. A stud extends from to the piston with a stud head remote from the piston. The stud head fits through the opening of the closer of the cover and flange and through a wider portion of the anchor plate hole, and is positioned opposite the flange and cover from the piston when the cover is positioned over the flange. The stud head does not fit through a narrower portion of the anchor plate hole. A resilient member biases the piston away from the cover. A selectively activated actuator overcomes the resilient member and forces the stud head away from the flange and the anchor plate.

Abstract: A predominantly liquid filled, vapor-liquid chemical reactor having an improved distributor plate assembly is disclosed. At least one of the plates in the assembly is formed with an active area having a plurality of apertures formed through the plate, an opening, and a downwardly depending lip proximate the opening. As vapor ascends through the reactor, the plate and the lip cooperate to trap the vapor upwardly against the bottom of the plate, forming a vapor region. This vapor region facilitates vapor liquid interaction and the flow pattern of liquid through the reactor.

Abstract: A combined cycle power generation system incorporates a carbonizer and a pressurized fluidized bed reactor for the generation of fuel gas and flue gases, respectively. A combustor is provided for the combustion of the fuel gas in the presence of the flue gases to produce hot gases. The hot gases are passed through a gas turbine where the gases expand and cool while performing work in the generation of electrical power. The exhaust gases from the gas turbine are passed though a heat recovery unit for the production of steam. The exhaust gases are then combined with air and passed to the pressurized fluidized bed reactor to provide excess secondary gas to aid in driving the gas turbine.

Abstract: A closure device adapted for attachment onto the upper head of a coking drum to prevent hot vapors escaping during drum decoking operations. The closure device includes a cylindrical-shaped housing having a rotatable ball valve and horizontal elongated stem provided in its lower portion, and a cover unit including a packing gland provided at the housing upper end. A rotatable cutting tool provided within the housing above the ball valve has a drive rod extending upwardly through the cover unit packing gland. During operations, the ball valve is opened and the drive rod and its attached cutting tool can be extended downwardly through the ball valve cylindrical-shaped opening into the coking drum and rotated, so as to cut and dislodge coke deposited in the drum.
