Abstract
A process for suppressing foam formation in a vessel includes the steps of feeding a liquid and a gas to a vessel at a liquid velocity and a gas velocity respectively; adding particles of a solid material to the liquid, the particles having a particle size and particle density; and selecting at least one of the liquid velocity, particle size and particle density so as to fluidize the particles in the liquid, whereby foam formation in the vessel is suppressed. The particles are preferably liquid phase phobic particles.
