The Population Balance

The Crystal Length-based Population Balance Equation

In crystallization as a separation process, the separability of the particles from the mother liquor by, for example, filtration are of utmost importance, as well as their washability and drying. The efficiency of these processes is directly related to the crystal size distribution (CSD) of the solid, and as soon as the CSD of the solid phase becomes an interesting product specification, the population balance equation (PBE) must be introduced. The PBE describes how the size distribution develops in time as a result of various kinetic processes. The concept of the PBE was introduced to crystallization by Randolph. A general form of the PBE is as follows:

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
