摘要

Process for reducing the foam produced during vaporization or gasification of foam-forming liquids comprises feeding the vapor or gas into the space above the liquid at the start and/or during vaporization or gasification. Preferred Features: The vapor introduced is produced by vaporizing the condensate from a temporary vaporization. Vapor produced from the vaporization is fed back into the space above the liquid. The gas introduced is fed back into the space above the liquid from the gasification in a partial stream. The gas necessary for the start of a discontinuous gasification process is removed from an intermediate storage device.
