Heterogeneous catalysis in industrial processes involves a complicated set of physical and chemical phenomena that help lead to products. This one-page reference provides information about the formation of products in an industrial process using solid catalyst materials. Catalyst materials…
Water-treatment programs for cooling towers have evolved in recent years, favoring non-phosphorus programs today. This article reviews the impact on water chemistry and operating reliability Cooling towers are a critical component of many industrial facilities. Cooling towers evaporate only pure…
When properly selected and stored, intermediate bulk containers (IBCs) can be used to safely transport products in the chemical process industries Demand within the global market for rigid intermediate bulk containers (IBCs) has grown at a steady rate in recent…
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…
A number of factors are involved in selecting the right intermediate bulk container (IBC). An overview is presented here An intermediate bulk container (IBC) is a large package for transporting chemicals into a plant or products from the plant. IBCs…
This article provides practical guidance for engineers and highlights the importance of combining mathematical skills, domain expertise and proper communications The role of mathematical models in chemical engineering keeps increasing, to the point that some engineers become specialized “modelers.” To…
