Dilute-phase conveying requires a lot of gas and operates at relatively high gas and solids velocities, possibly making issues of particle attrition, floss and fines, and erosion. Higher utility costs also can result. In this column, Ray discusses how dense-phase conveying can help alleviate these problems.
