Compabloc - compact performance Compabloc - the new laser welded heat exchanger series

more resistant to pressure peaks and cycling. This boosts the reliability and safety of the unit as well as providing better heat transfer performance. Flow paths The two media flow in alternately welded channels between the corrugated plates. They flow in a cross-flow arrangement within each pass (see figure at right) while the overall flow arrangement is counter-current for a multi-pass unit (see sectional view below). When required, the unit can be designed with overall co-current operation. Each pass is separated from the adjacent passes by a pressed baffle, Panel Heat transfer plate pack...

Flow configurations for different duties Compabloc can be designed with both single-pass or multi-pass flow configurations. For condensation and liquid-toliquid duties without temperature cross, the single-pass configuration is suitable with its total cross-flow. For duties with temperature cross and close temperature approaches, a multipass configuration is suitable. Each pass is in cross-flow, but the overall flow pattern within the heat exchanger is counter-current. The configuration of Compabloc has unique advantages that permit: • a different number of passes on the two circuits, thereby...

Compabloc as pre-heater, condenser and reboiler column condenser reboiler pre-heater vapour non-condensable gases condensate vapour/liquid mixture liquid condensate steam Reboiler Two-pass process condenser with gas/liquid seperation • Compactness – takes only a fraction of the floor space of a shell-and-tube heat exchanger. Condensation & evaporation In condensing and evaporating duties, the Compabloc provides additional advantages: • Large cross-flow area and short flow path – fit low-pressure condensing duties and allow very low pressure drops. Designed with demanding duties in mind When it...
