Overcoming pressure-drop constraints
Acceptable Compressor KOD (ΔP) under vacuum or very low suction pressure conditions is very low. Generally, lower the pressure-drop across an ME, lower is its mist capturing efficiency and higher is the possibilty of liquids entering into the compressor. Where low ΔP is critical and not high mist capture efficiency (MCE), a vane unit or low density mesh pad suffices. However, a dual density mesh pad consisting of entry side low density mesh and exit side high density mesh also offers high capture efficiency at marginally higher ΔP.
