An absorber intercooler having a heat exchanger formed integrally therein. The absorber intercooler includes a cylindrical outer casing having a tube bundle disposed longitudinally therein. Inlet and outlet ports are provided in the cylindrical casing to allow for the flow of refrigerant around the tube bundle. Upper and lower end plates, having a plurality of openings therein, seal the upper and lower ends of the bundle. A liquid inlet pipe provides a flow of liquid absorbent through the upper end plate into the tube bundle. A vapor inlet pipe provides a flow of vapor into the bottom of the intercooler, and the vapor flows through a central opening in the lower end plate into a centrally disposed vapor flow pipe. The vapor flows upwardly therein through the upper end plate. A cap is provided on the upper end of the vapor flow pipe to prevent liquid absorbent from flowing down into the pipe, and also provides for an even radial distribution of the vapors at the cap. A distributor pan is positioned below the aforementioned cap, and provides for an even distribution of the resultant liquid into the tube bundle.

Absorber intercooler

A continuously operated liquid-solids separator for separating a powdered resin material suspended in water forming a slurry by permitting the resin, which is of a lower specific gravity than the water, to float or be impelled upwardly within a separator vessel or upright tank from which it is withdrawn through an outlet orifice as a thickened slurry. Anti-swirl baffles in the form of vertically extending plate members are located in circumferentially spaced relationship interiorly of the vessel in at least the upper regions thereof in order to restrict the undue agitation and swirling of the resinous material and limit resultant downward movement thereof as it floats upwardly within the liquid towards the outlet orifice, while agitation is imparted to the thickened slurry in the uppermost region of the separator vessel through the intermediary of a suitable rotatable impeller mounted in the upper section of the vessel proximate and at a level below the outlet orifice in order to maintain the accumulated resin or particulate material uniformly dispersed in the thickened slurry as the latter is being withdrawn from the separator. A generally horizontal stilling baffle or screen extends across the separator vessel between the inlet orifice for the solids-liquid suspension or slurry and an outlet orifice for the purer or clarified liquid located proximate the bottom of the separator.
