Dilute or Dense Phase Pneumatic Conveying? | AIChE
Typically, a dilute phase line conveys less than 15 lb (~7 kg) of solids per pound (~0.5 kg) of gas at a pressure of less than 15 psig (~1 barg). Dense phase. This occurs when particles are conveyed in the gas stream at a velocity that is less than the saltation velocity. Two modes of flow can result in dense phase, namely piston/plug flow and ...
