Understanding Attrition in Solids Processing

Better qualitative and quantitative understanding of the mechanisms of particle breakage at the level of the particles, the bulk material and the equipment helps minimize the risk, uncertainties and impact of particle attrition in solids processing operations Unwanted breakage, degradation…

Facts At Your Fingertips: Design Considerations for Pneumatic Conveying

Attention to the design of bulk-solids pneumatic-conveying pipelines can help avoid conveying-system problems, such as low conveying rates, plugging, excessive wear-and-tear in the conveying line, high conveying-system pressure drop, product breakage, fines generation and product cross-contamination. This one-page reference provides…

Considerations for Solid Catalyst Loading

Special considerations must be made for loading expensive solid catalyst materials into fixed-bed and tubular reactors Most units in the chemical process industries (CPI) use complex and expensive heterogeneous catalysts aimed at improving reaction performance. Although sometimes overlooked, the solids-handling…

Facts At Your Fingertips: Adsorption bonding

Physical adsorption phenomena play a critical role in many separation and purification processes, including separations of industrial gases, purification of gases, moisture removal from fluids, water purification and others. Adsorption is a surface phenomenon in which a fluid (gas or…
