To avoid problems with solids flow in bins and hoppers, the friction between the equipment walls and the flowing solids is an important factor to understand. Provided here is a review of flow patterns in bins and hoppers, and practical…
Tumble-growth agglomeration can reduce dust in solids-handling processes. Here’s how it works Handling and processing bulk solids appears in nearly every industrial sector, from energy to agriculture. Dust is a ubiquitous and challenging issue when working with bulk solids, because…
The following list is a selection of recently published books with relevance for the chemical process industries (CPI), July 2019 Guidelines for Investigating Process Safety Incidents, 3rd ed. By the Center for Chemical Process Safety, Wiley/AIChE Publishing, 2019, 408 pages,…
Several methods and calculations are available for determining particle size and particle-size distribution. This article provides and overview on how to use them The behavior of particulate material is greatly dependent on its geometric properties, including particle size, shape and…
Paying closer attention to the air-filtration systems of pneumatic conveying operations can avoid losses in efficiency in compressed-air usage during filter cleaning The inefficient use of compressed air in solids-handling processes, such as pneumatic conveying, can waste a significant amount…
By focusing on ignition sources, such as static discharges, and housekeeping, facilities handling solids can minimize their risk for combustible dust explosions Dust explosions in industrial facilities can cause injuries, destruction of property, and — as history will attest —…
Adjustment and control of moisture levels in solid materials is a critical aspect in the manufacture of many chemical products. Drying can be defined as the vaporization and removal of water or other liquids from a solution, suspension, or other…
