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 use their knowledge of chemistry, physics, engineering and biology to find solutions to challenges involving things like materials manufacturing and food processing.
They may spend time at industrial plants, refineries, and other locations, where they monitor or direct operations or solve onsite problems. Nearly all chemical engineers work full time. How to Become a Chemical Engineer. Chemical engineers must have a bachelorâs degree in chemical engineering or a related field.
