Abstract
1533022 Separating particles from gas ASHLAND OIL INC 19 March 1976 [24 March 1975] 11230/76 Headings BIT and B2P An apparatus for separating solid or liquid particles from a gas stream in which they are suspended comprises a chamber 12, a conduit 10 through which the particle-laden gas stream flows, the conduit having an outlet opening 13 leading into the chamber and a side wall port 17 upstream of the opening 13, and a cyclone separator 19 having an inlet connected to the port 17. The apparatus is described in relation to the separation of fine solid catalyst particles from gases produced in catalytic "riser cracking" of petroleum. The conduit 10 is in the form of a riser pipe which enters a gas-disengaging vessel from below and opens at 13 into the disengaging or separating chamber 12. The upper end of the riser pipe is stiffened at 25. As shown, there are two ports 17 in the side wall of the conduit 10 connected to a pair of cyclones 19 which are connected by expansion joints 22 to gas outlet conduits 21 connected to a further pair of cyclones 28 which have gas discharge outlets 30 leading out of the vessel 11 to fractionators. The cyclones 19, 28 have dip legs 20, 29 for discharging separated catalyst particles to the bottom of the vessel 11 from which they are led to a regenerator. The chamber 12 is pressurized by being connected directly to the conduit 10 so that no gas circulation takes place in the chamber. In operation, as the gases are abruptly diverted from the conduit 10 through the ports 17 into the cyclones which are at a lower pressure, the bulk of the catalyst particles are separated from them and are carried by their momentum through the opening 13 into the chamber 12 where they impinge on a deflector 14 which direct them downwardly to the bottom of the chamber. A baffle 33, Fig. 4, may be provided inwardly of the conduit 10 upstream of the port 17 to deflect the particles away from the port. In modifications, the conduit 10 may enter the chamber 12 through its side or top and the cyclones maybe disposed outside of the chamber. Other uses of the apparatus are given.
