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.
Chemical engineers held about 33,300 jobs in 2012. Chemical engineers work mostly in offices or laboratories. They may spend time at industrial plants, refineries, and other locations, where they monitor or direct operations or solve onsite problems.
Since chemical engineers are taught to understand how an entire industrial process or how an entire plant works, they are often promoted to managers. They quickly ascend the corporate ladder. Five or six years out of college, the majority of chemical engineers are managers.
