What Does High Hemoglobin Mean? High hemoglobin levels mean that measured hemoglobin levels are above the upper limits of normal for the age and sex of the person (see above normal values). For example, a 19 year old that has a detected hemoglobin level of above 17.7 g/dl would have a high hemoglobin level.
Some chemical engineers specialize in a particular process, such as oxidation (a reaction of oxygen with chemicals to make other chemicals) or polymerization (making plastics and resins).
A variety of industries employ chemical engineers, representing a diverse range of products, employers, and services. The focus of companies in this industry is on the development, extraction, isolation, combination, and use of chemicals and chemical by-products. Chemical engineers design and operate processes and systems to combine, transport, separate, handle, recycle, and store them.
