FIELD: process engineering.
SUBSTANCE: invention is intended for separation of solid particles from gases. Proposed process comprises the steps that follow. Catalyst is recovered in regenerator and solid particles are separated in the first and second stage cyclones. Gas flow is forced from second stage separator into third stage external separator. Gas flow is directed from said external separator into cyclone recycling unit to get a clean gas flow. Solid particles are charged to cause their agglomeration in said recycling unit. In implementation of this process, extra flow is fed from cyclone recycling unit into third stage external separator. Another flow is fed therefrom into the filter. Separate gas flow derived from the filter is fed into offgas heat recovery system and, then, into chimney. Additional flow from cyclone recycling unit is fed into the filter. DC electric field is created in said cyclone recycling unit.
EFFECT: higher quality of gas cleaning.
