Abstract
A method and a device for controlling the flow through a distillation apparatus for separating components of a mixture, particularly a dissolved substance, such as an oil, a wax, a polishing agent or alike, from a liquid mixture, particlularly containing a chlorinated solvent, such as tri- or perchlorethylene. According to the present invention, the feeding of new liquid mixture or solution into the boiling vessel of the distillation apparatus is controlled in response to the liquid level in the boiling vessel, whereas the draining of substance-enriched liquid or separated substance from the boiling vessel is controlled in response to the distillation temperature, or to a variable being co-variant therewith, so as to maintain the distillation temperature within predetermined limits and the flow through the apparatus at an optimal, high level.
