Patent GB-2038972-A (GB)
Title: Flange sealing joint with removable metal gasket
IPC: F16L23/02
Filed: 1979-12-03
Abstract: An all-metal joint is provided wherein a metal gasket 31 disposed between mating flanges 10, 20 can readily be removed when the joint is disassembled. Opposing faces of the mating flanges are configured to provide a recess between the flanges in which a soft metal gasket of annular configuration can be received when the flanges are coupled together. Symmetrically disposed ridges 13, 23 on the opposing flange faces penetrate into a peripheral region of the gasket, thereby causing a portion of the gasket material to flow into an annular groove that forms the periphery of the recess between the opposing flange faces. This compressed flange material in the annular groove provides a gas-tight seal between the mating flanges. The configuration of the opposing flange faces is such that when the joint is disassembled, the net force tending to retain the gasket in position against either one of the flange faces is minimized. In particular, each flange face is configured so that the residual compressive forces present when the flange coupling mechanism is released, distributed over the surface of the gasket, are in net effect substantially equal to or greater than the frictional and bonding forces that might tend to retain the gasket in contact with either flange. <IMAGE>

Title: Catalyst regeneration process and apparatus
IPC: B01J23/90
Filed: 1980-02-19
Abstract: In the regeneration of a spent hydrocarbon conversion (e.g. FCC) catalyst, hot regenerated catalyst is recycled (6, 39) from a dense bed (17) in the regeneration zone to mix with incoming spent catalyst (28) in a riser- mixer (4). The riser-mixer operates in dense phase and is supplied with a relatively small amount of an oxygen- containing regeneration gas as fluidizing medium (34, 44), preferably air. After the mixing of spent and regenerated catalyst is substantially completed, a relatively large amount of a oxygen-containing regenerating gas, preferably air, is admixed (40, 41) with the catalyst mixture, and some coke oxidation occurs. The balance of coke oxidation takes place in a downstream-situated regeneration zone (1) of substantially conventional design. The regenerating gas addition is preferably made at the base of a cone-shaped transition zone (5) in order to provide a venturi effect which ensures good regeneration gas-catalyst mixing. <IMAGE>
