Miscible antifoams are provided that do not separate out of a target liquid and that are easy to incorporate in the target liquid. A method or system involves mixing a liquid (‘a miscible antifoam’) into a target foaming liquid. This miscible antifoam is engineered/chosen such that it has both a higher surface tension and is more volatile than the target liquid, or engineered such that it has both a lower surface tension and is less volatility than the target liquid. The miscible antifoam leads to surface tension gradients that cause bubble rupture up to 10 times faster than the target liquid without the antifoam. Further, the miscible antifoams are easy to incorporate and do not separate out from the target liquid during operation—both of which are key limitations faced by existing antifoams.
A method of controlling foam using a miscible antifoam formulation, comprising:
