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.
In the field of engineering, a chemical engineer is a professional, who is equipped with the knowledge of chemical engineering, works principally in the chemical industry to convert basic raw materials into a variety of products, and deals with the design and operation of plants and equipment.hemical engineering is a male-dominated field: as of 2009, only 17.1% of professional chemical engineers are women. However, that trend is expected to shift as the number of female students in the field continues to increase.
