Abstract

A method for blending dry material in a plant comprises automatically controlling fluidization of the dry material, transfer of the material, or both. In various embodiments, the automatically controlling comprises optimizing an amount of time that the dry material is fluidized prior to transfer, optimizing the transfer rate of the dry material, detecting and eliminating a developing plug of the dry material, estimating the weight of the dry material in the transfer line, minimizing dribbling during transfer of the dry material, and combinations thereof.
