Reliable and Cost-Effective Solids Feeding

By Richard Farnish, University of Greenwich |

A holistic approach to bulk-solids-feeding installations can improve the effectiveness and efficiency of operations involving solids handling Many chemical processes involve the extraction of bulk solid materials at a controlled rate from a storage vessel for delivery into the process. The extraction of solid materials usually requires the use of technology that can deliver the solids into the process at the required feedrate and with minimal variation in rate when in operation. For every industrial installation, bulk solid material type and set of process requirements, a different optimal technology exists. This article presents some of the key considerations involved in obtaining reliable and cost-effective extraction from storage vessels. One of the most important aspects of efficient feeder installation is to understand that adopting a holistic approach is required to optimize any type of feeder and solids-feeding process. Such an approach considers the storage vessel, the interface between the storage vessel and the feeder along with the feeder itself as a single project entity whereby each element of the process must be specified and designed to work together. For “clean sheet of paper” projects, this approach is usually…
