摘要： A tangential flow filtration apparatus which utilizes a single manifold to introduce liquid to be filtered into the apparatus and to remove a filtrate stream and a retentate stream from the apparatus is provided. A plurality of filtration members are stacked in a vertical arrangement between the manifold and a plate. Holes and sealing means are provided within the filtration member to effect vertical flow of the filtrate, retentate and incoming liquid through the stack while preventing admixture of the filtrate with the retentate or the incoming liquid.

摘要： A tubular element for removing particulate matter and bacteria of dimensions in excess of a predetermined value from a fluid flowing from the interior to the exterior of the filtration element has a first inner layer of a highly porous material that has a low coefficient of sliding friction, and a second layer of a microporous filtration material having pores of substantially uniform size. The element may include an outer support layer of a porous material that is not subject to shedding. In a preferred form, the inner layer is formed from a high wet strength paper, the microporous filtration layer has sufficiently small pores to remove all bacteria from the fluid, and the outer layer may be a fine porous plastic sheet material or a high wet strength, high porosity paper that is impregnated with the polymeric material that forms the microporous filtration material. The fine pore structure of the outer layer supports the fragile filtration layer. In a preferred form, both ends of the tubular element are impregnated with a suitable sealing material such as a polyurethane potting compound. The ends are preferably dipped in the sealing material to a predetermined depth. When cured, these end portions provide additional mechanical support for the tube ends and block the passage of particulate matter and bacteria past the filtration layer at its edge. A fabrication process for the filtration element that does not damage the fragile microporous filtration layer involves helically wrapping the inner layer on a fixed mandrel to act as a carrier, and helically wrapping an overlying layer of the microporous filtration material. If an outer layer is used this is wrapped on the microporous material. All layers move in unison along the longitudinal axis of the mandrel. Each layer is self-overlapping and at least the filtration layer is sealed in the area of the overlap.

摘要： A technique is described which enables agglomerating coals (caking coals) to be flash pyrolyzed in a fluidized-bed reactor without agglomerates forming in the fluidized-bed. The technique requires the inert particles of the fluidized-bed to be coarser and denser than the particulate coal being pyrolyzed. With this arrangement the momentum of the inert particles in the fluidized-bed is believed to destroy the agglomerates as they form.

摘要： A filtration system is provided that directs a fluid to be filtered through a disposable tubular filtration element, supports the filtration element, and accommodates for "wet growth" of the filtration element. The system operates with an inside-to-outside forced fluid flow through the filtration element and includes a generally cylindrical housing with a fluid inlet and outlet. A perforated outer support screen is mounted within the housing and surrounds the walls of the tubular filtration element with slight clearance. Under the influence of the fluid pressure and the wet growth, the walls of the filtration element bear against the screen. A sealing and support assembly having upstream and downstream fluid guides, each carrying, in a preferred form, a pair of resilient sealing members, is positioned inside the filtration element. A rigid inner member bridges the opposing faces of the resilient member pairs. A rod and nut arrangement draws the flow guides towards one another to apply a longitudinal compressive force on the resilient members caught between a flange on the flow guides and the rigid inner member. This compressive force deforms the resilient members in a radially outward direction to seal the filtration element to the housing and isolate the filtered fluid. In a preferred form, the adjacent faces of each pair of resilient members are aligned with the interior edge of an impregnated end portion of the filtration element. In addition, a tubular prefiltration element may be positioned inside the rigid inner member.

摘要： A process for the production of ethylene from a methane rich gas stream and an ethane rich gas stream. The process comprises the steps of:(a) introducing the methane rich gas stream together with molecular oxygen into a lower zone of a fluidized-bed of particles which are catalytically active in promoting an exothermic oxidative coupling reaction to produce ethylene and other hydrocarbons,(b) mixing the ethane rich gas stream into the fluidized-bed above the level at which substantially all of the molecular oxygen has been consumed, and(c) subjecting the mixture resulting from step (b) to an endothermic pyrolysis reaction in an upper zone of the fluidized-bed to produce further ethylene and other olefinically unsaturated hydrocarbons.The process is characterized in that the pyrolysis step (c) is carried out substantially without the addition of heat to the reactor, other than the heat content of the methane rich and ethane rich gas streams and the heat generated by the exothermic oxidative coupling reaction. The fluidized bed particles are desirably caused to circulate within the reactor in such a manner that there is an efficient transfer of exothermic heat from the oxidative coupling zone to the pyrolysis zone so that the reactions of steps (a) and (c) occur at substantially the same temperature.
