FIELD: chemistry.
SUBSTANCE: invention can be used in chemical industry. Apparatus for producing liquid sulfur dioxide contains a sulfur melting and filtration unit, a sulfur pump, a sulfur furnace, a sulfur vapor condenser, an oxygen supply line to a sulfur furnace, a sulfur dioxide condenser, a refrigerating unit, a liquid sulfur dioxide pump and heat exchangers. Sulfur furnace is combined with condenser of sulfur vapors in one device. Plant is equipped with a sanitary tower loaded with adsorbent for absorption of uncondensed sulfur dioxide.
EFFECT: invention reduces power consumption, improves installation reliability due to elimination of crystallisation of liquid sulfur in equipment, increases environmental friendliness.
