  • Separation of gases from particle streams
    Patent number: 4313910
    Abstract: An apparatus for separating a carrier gas from a particle stream is disclosed which comprises deflecting said particle stream about a curved surface to compact the stream and separate therefrom a major proportion of said carrier gas, and introducing a substitute fluid into said compacted stream via at least one aperture in said curved surface to displace substantially the remainder of the carrier gas from the spaces between the particles. The invention is usefully applied for rapid disengagement of gases from a particulate stream, particularly in the catalytic cracking of hydrocarbons.
