Multiple hydrocyclone apparatus including plural loop-like arrays of hydrocyclones is provided with a walkway space inside the innermost array. A passageway is provided to permit entry of an operator into the walkway space for inspection and repair of the inner hydrocyclones. The apparatus may be made in an elongated form to fit available mounting space. Baffles may be provided within the feed plenum for directing the flow of feed stock. Appropriate devices may be provided for bleeding minor portions of the feed stock from the feed plenum to maintain the velocity of the stock flowing within the plenum.

Multiple hydrocyclone apparatus

Systems for evacuating process fluids having condensable and incondensable components, especially those including corrosive constituents, include a condenser for condensing at least part of the condensable component and discharging the condensate from the system, a jet diffuser supplied with atmospheric air as a motivating fluid for diluting and increasing the pressure of the uncondensed portion of the process fluid, and a liquid ring suction pump for further increasing the pressure of the diluted uncondensed process fluid and discharging it from the system.
