ABSTRACT:
An improved apparatus for separating solid particles from vapor is disclosed which in one embodiment employs at least one zone defined by at least two generally vertical and at least two generally horizontal vanes and in another embodiment optionally employs at least one vane to inhibit turbulence in a lower portion of this apparatus to aid the settling of particles within a particle outlet means.
This apparatus is particularly suited to at least partially separating solid particles from a mixture of vapors and solid particles which arise either when restoring the catalytic activity of solid particles that had previously been used to promote a chemical conversion or when carrying out a chemical conversion, such as for example hydrocarbon cracking or reforming.
Improved methods employing such apparatus are also disclosed.
