Variation of properties in the dense phase region; Part 2 .

The dense phase has a viscosity similar to that of a gas, but a density closer to that of a liquid. Because of its unique properties, dense phase has become attractive for transportation of natural gas. Pipelines have been built to transport natural gas in the dense phase region due to its higher density.

Pneumatic Conveying - Dilute phase - Dense phase Design .

VACUUM dense phase. Vacuum dense phase will present a quite similar setup than the lean phase one. However, in order to accomodate higher solids loads, leading to higher pressure drop, a vacuum pump will be used instead of a simple roots Blower. Very high vacuum will then be generated.

Dense Phase Conveying Equipment – Coperion

Dense phase systems convey materials at slower velocity than traditional dilute phase pneumatic systems. Unlike dilute phase conveying, in which all the material is suspended in a high speed gas stream, dense phase conveying moves material in a slower but more concentrated manner, especially along the bottom of the pipeline.

Dense Phase Pneumatic Conveying – Cyclonaire

Dense phase pneumatic conveying is a relatively low-speed system where the material is not suspended in the air stream. The low velocity of dense phase means less wear and tear on both the system and the materials being conveyed. The velocity is typically set between 400 ft./min. and 1,000 ft./min., though there are several forms of dense .
