In many cases non-zinc anodes outperform actual zinc anodes, depending upon the type of metal you need to protect and the nature of the water in which the metal being protected is immersed. It all has to do with the voltage of the anode when referenced against a standard.
Chemical engineers at pharmaceutical manufacturers have the same duties as those of consumer goods manufacturers, but they have additional duties as well. Their focus is on developing new drugs or products to enhance the health of humans and animals.
Nearly all chemical engineers work full time. Occasionally, they may have to work additional hours to meet production targets and design standards or to troubleshoot problems with manufacturing processes. About 2 out of 5 chemical engineers worked more than 40 hours per week in 2016.
