Desiccant air dryers - Atlas Copco

Desiccant dryers consist of two towers filled with desiccant such as activated alumina, molecular sieves or silica gel. Wet compressed air passes directly through the substance, which adsorbs the moisture. The desiccant has a finite adsorption capacity before it must be dried out. Hence the twin tower design.

Chemical weapons in World War I - Wikipedia

The use of toxic chemicals as weapons dates back thousands of years, but the first large scale use of chemical weapons was during World War I. They were primarily used to demoralize, injure, and kill entrenched defenders, against whom the indiscriminate and generally very slow-moving or static nature of gas clouds would be most effective.
