| 1. For use in a process that includes a foam laden gas stream in which the presence of foam results in the carry over of liquids
and/or solids, the method comprising:
injecting the foam laden stream tangentially into a cyclonic separator having a gas outlet and a liquid outlet under pressurized
conditions in which the gas stream is subjected to centrifugally generated gravitational force sufficient to substantially
collapse the foam, providing an outlet gas stream that is substantially liquids, solids and foam free.
