Insights into mass transfer in chemical processes
Thread Content
Mass transfer is one of the most common chemical processes. Packed absorption towers can be regarded as a typical example of mass transfer; the circulating liquid is sprayed from top to bottom, while flue gas flows from bottom to top. Some components in the flue gas are absorbed by the circulating liquid. In mass transfer, some are targets for aggregation, and some are targets for dispersion. Sometimes, to achieve the desired objectives, it is necessary to take indirect approaches; for example, the airflow distribution in a packed absorption tower and the even distribution of liquid by a liquid distributor are very important for improving the absorption efficiency.
