Facts at your Fingertips: Nucleation Phenomena in Crystallization

Industrial crystallization processes are widely used in the chemical process industries (CPI) for their ability to separate and purify products in a single step, often to greater than 99.9% purity. Crystal growth proceeds after nucleation, a molecular aggregation process whereby…

Steam Quality Considerations

Steam often provides the majority of heat, but its quality is not always carefully managed. Here are some tips on how to improve and maintain steam quality Plant operations focus on production activity, maintaining tight control on process algorithms, feedstocks…

High-Purity Water Simplified

There are a number of process technologies available to meet the strict standards for high-purity water in different industrial sectors It is easy to think that the water coming out of our faucets can be used anywhere. Although potable water…

Detection Systems for Reducing the Risk of Hydrogen Fires

Today’s detection equipment can provide early sensing of H2 gas and flames, provide alarm information to a fire- and gas-safety system controller to initiate mitigating measures, and integrate with process control to further minimize H2-fire risk Hydrogen is the most…

Facts at your Fingertips: Distillation Trays and Packing

Industrial distillation columns use either trays or packing to promote vapor-liquid contact in separating the components of liquid mixtures to the desired purity. Approximately one half of columns are equipped with trays globally, and the other half contain packings. This…

Batch Drying: Maximizing Product Yields

Use the strategies discussed here to maximize the yields of solid products from batch drying vessels Successfully drying a wet solid in a drying vessel does not complete the operation — the dry solids must be removed from the vessel.…
