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 chemical engineer develops raw materials into a range of useful products. A career in the field offers you the chance to create things such as petrochemicals, medicine and plastics. As a chemical engineer, you will be involved in the design and development of a diverse range of products.
