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.
Chemical engineers use their knowledge in chemistry, mathematics, and biology to design and develop products in the healthcare, pharmaceutical and energy industries, among others. There are many different roles a chemical engineer could have.
