Description

For process operators throughout the chemical process industries (CPI), the need to effectively and efficiently mix and blend powders and other bulk solids presents many challenges. For instance, engineering challenges arise when it comes to selecting and specifying the most appropriate mixer or blender to meet the needs of the process and the physical and chemical attributes of the powders (and thus dictate bulk solids behavior), and there is always a need to protect workers and safeguard the environment during operation and maintenance of these systems.

This selection of practical tutorial-style engineering articles provides informative, actionable information for process engineers and other technical professionals throughout the CPI. Several topics discuss different mixer and blender options. Others provide targeted engineering recommendations on how to manage specific safety issues— such as the risk of dust explosions — that can arise when handling powders and other bulk solids.

All of these articles in this PDF guidebook were published in Chemical Engineering magazine between 2009 and 2020. Volume 1 of this series — entitled “Mixing & Blending: Volume 1 — Combining Liquids” — is available separately.

Delivered in a PDF format. 87 Pages.

Topics Include:

Taking Representative Samples in Solids Handling Processes

Non-representative sampling in solids processes has costly consequences. A better understanding of the mathematical basis for sampling and of acceptable quality levels can help to alleviate potential sampling issues and more closely approximate reality

Selection of Silos for Bulk Storage

To determine what kind of storage silo is best for your site and your materials, begin by answering the following five questions
