ABSTRACT:
The invention relates to a method for controlling and optionally regulating the level of liquid P.sub.2 S.sub.5 in a cooling device. To this end, an inert gas is introduced into the cooling apparatus arranged in inclined position. More particularly, the inert gas is introduced into the cooling apparatus' lower end portion through an inlet opening thereinto near a P.sub.2 S.sub.5 -feed inlet, and forced to bubble through the liquid P.sub.2 S.sub.5. The pressure difference which establishes in accordance with the P.sub.2 S.sub.5 liquid level in the device is measured and variations in the respective pressure difference are utilized for regulating the supply of liquid P.sub.2 S.sub.5 to the cooling device so as to maintain a predetermined liquid level therein.
