ABSTRACT:
A vacuum receiver comprising a closed top vertical cylindrical tank with a central vacuum takeoff at the top, a tangential downwardly inclined feed conduit in the sidewall, an inverted conical bottom section with anti-swirl baffles therein, and a barometric leg extending downwardly from the apex of the bottom to termination in submergence in a lower seal tank. A conduit is provided to recycle a portion of discharge liquor from the seal tank to the top of the barometric leg. The slope of the conical bottom does not exceed about 40.degree. from the vertical wall and inclination of the inlet conduit is about 15.degree. from horizontal. The barometric leg length and diameter as well as the liquor recycle rate are selected to optimize final liquor discharge rate at prevailing vacuum and foam conditions.
