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).
Chemical engineers have the opportunity to enjoy a diverse career, and there are a range of different jobs from which to choose. You can work in a laboratory, in an office, in the outdoors or on an industrial plant, or combination of all of these in the one job.
