Aerosol formation during absorption processes - Causes and solution strategies

If a gas phase contains inerts or components with a wide range of volatilit y then supercooling may occur during an absorption or partial condensation process. The resulting supersaturation can lead to aerosol formation in the presence of condensation nuclei. During the production and processing of c hemical products aerosol formation can lean, far instance, to corrosion, no n-fulfilment of specifications, or catalyst poisoning. Aerosol separators o ften represent a costly problem solution because they consume energy and re quire additional investment, whereas the avoidance of aerosol formation, if possible, represents a cost-favourable alternative, In this article, the c auses of aerosol Formation are analysed and four strategies for solving the problem of aerosol formation are developed. Industrial aerosol problems ar e considered to illustrate how these strategies can be implemented in pract ice.
