Beschreibung
Zusammenfassung:The invention relates to a method for controlling and optionally regulating the level of liquid P2S5 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 P2S5-feed inlet, and forced to bubble through the liquid P2S5. The pressure difference which establishes in accordance with the P2S5 liquid level in the device is measured and variations in the respective pressure difference are utilized for regulating the supply of liquid P2S5 to the cooling device so as to maintain a predetermined liquid level therein.
