The dense phase is a high concentration of product. It moves forward as plugs or dunes. The quantity of air is significantly lower than for the diluted phase (10 to 20x less for the same product) but the head loss is high (transport pressure up to 7 bars).
The SABE pressurised dense phase is to be used for:
The SABE pressurised dense phase should be avoided for:
The SABE vacuum dense phase is used for:
