High Purity Chemicals: Processing Equipment Essentials

By William M. (Bill) Huitt |

Some practical tips regarding the design and fabrication of piping systems and equipment for high-purity applications are presented here Figure 1. The evolution of high-purity equipment can follow the steps shown here[/caption] Chemical processing, and the chemical process industries (CPI) on the whole, have evolved lightyears beyond their very beginnings — beginnings in which chemistry was more or less a form of alchemy and the mixing of basic natural elements. From such humble beginnings, and more pointedly over the past several decades, the chemical industry has progressed dramatically from those early times to today’s high-tech chemical processing, which include bioprocessing and the electronics industry. These are two industries that not only rely on what is referred to as high-purity, ultrahigh-purity, and ultra-pure chemistry, they could not exist without it. This discussion does not focus on the chemistry itself, but on the various nuances in the equipment used to manufacture, monitor and handle these chemicals.   The purity quotient Since the topic of this discussion focuses on what is vaguely termed “high purity,” “ultrahigh purity,” and “ultra-pure” chemical processing, we need to provide some clarification…
