Coalescers cross-flow devices

Cross-flow device sizing. Cross-flow devices obey the same genera) sizing equations as plate coalescers. Although some manufacturers claim these units arc more efficient than CPIs, the reason for this is neither apparent from theory nor from lab or field tests. 

Cross-flow devices obey the same general sizing equations as plate coalescers. Although some manufacturers claim greater efficiency than CPIs, the reason for this is not apparent from theory, laboratory, or field tests as a result, verification is unavailable. If the height and width of these cross-flow packs are known. Equations (3.18a) and (3.18b) can be used directly. It may be necessary to include an efficiency term, normally 0.75, in the denominator on the right side of Equations (3.18a) and (3.18b) if the dimensions of H or W are large and a spreader is needed.
