METHOD AND DEVICE FOR THE DEGASSING OF LIQUID SULFUR Russian patent published in 2017 - IPC B01D19/00 C01B17/02 

FIELD: chemistry.

SUBSTANCE: way to implement in different, not completely isolated cells, each of which is filled with liquid sulfur first zone and gas filled second zone. Liquid sulfur is pumped from the first zone of each of the chambers in the second zone of this same chamber and sprayed in the area. In the first zone of the first camera insufflated with oxygen-containing gas to remove the H₂S, and in the first zone chamber, located after the first chamber, insufflated with inert gas to remove SO₂. The device contains a container (1), split by partition (4) into two not completely isolated one from another chambers (a, b) filled with liquid sulfur first zone (2) and gas filled second zone (3). The first blowing device (12) is located in the first zone (2) of chamber (b) for oxygen-containing gas injection into liquid sulfur, the second blowing device (31)-in the first zone (2) of chamber (c) after the camera (b) for injection of inert gas into a liquid sulfur. Incoming into the second zone (3) of chamber (b) of the first device (25') for spraying liquid sulfur connected with pump (21'), suction liquid sulfur from the first zone (2) of chamber (b). Incoming into the second zone (3) of chamber (c) second device (25") for spraying liquid sulfur connected with pump (21"), suction liquid sulfur from the first zone (2) of chamber (c).

EFFECT: effective removal of gases contained in the liquid sulphur, low level of SO₂ formation.
