The chrome 6 was eventually released into the ambient air and the groundwater in the surrounding area. One strategy for reducing fugitive emissions is to reduce the number of these units by reducing or eliminating backup units and redundancy. This strategy will reduce routine air releases but will increase the probability of a catastrophic release or other safety incidents. Simply put, the objective of pollution prevention is to reduce the overall level of risk in all areas and not to shift risk from one population to another. Problem Example problem 9.3-3 Estimate the magnitude of the mixing effect on reaction yield.
Additional data is shown below.
Estimate the reaction yield as a fraction of the expected yield. Thus, the mixing in this reactor is almost sufficient to achieve the expected yield. Byproduct generation is not affected to a large degree by mixing in this CSTR, but could be improved slightly by operating the mixer at higher speeds. There are many solvents and processes developed over the past century to accomplish this step. The original process used a synthetic organic solvent to extract caffeine from un-roasted coffee beans.
