Abstract
A method for feeding a subliming material into a liquid is disclosed, by which the end of a pipe is submerged below the surface of the liquid, and a subliming, particulate material is propelled through the pipe and into the liquid by a flow of gas. The flow rate of the entraining gas is sufficient to prevent the formation of deposits on the interior walls of the pipe by countercurrent gaseous diffusion of the subliming material.
