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.
The difference between chemical engineers and other types of engineers is that they apply a knowledge of chemistry in addition to other engineering disciplines.Chemical engineers sometimes are called 'universal engineers' because their scientific and technical mastery is so broad.t is the branch of engineering concerned with the design, construction, and operation of machines and plants that perform chemical reactions to solve practical problems or make useful products.
