Abstract
A method of converting at least partially molten dibutyltin difluoride contained in a hot, waste gas stream into substantially dry, solid particles suitable for recovery by filtration through a porous bag filter. The method includes the steps of introducing a predetermined amount of liquid water into the stream, and vaporizing the liquid water to cool the gas and the molten dibutyltin difluoride to form substantially dry particles. The amount of liquid water is sufficient to effect the desired cooling without saturating the gas stream.
