METHOD OF PURIFICATION FROM SULFUR Russian patent published in 2014 - IPC B01D53/14 B01D53/48 B01D53/78 B01D53/86 B01D53/96 C01B17/00 

FIELD: chemistry.

SUBSTANCE: method of purification from sulfur includes continuous supply of acidic gaseous hydrocarbon, which contains hydrogen sulphide, into absorber, working under P1, which exceeding 100 ft/in², contact of acidic gas with water solution of catalyst in absorber to convert hydrogen sulphide into elementary sulfur in solid form and obtain waste solution of catalyst, which contains sulfur in solid form, removal of gas flow from absorber, pumping waste catalyst solution, which contains sulfur in solid form, into oxidiser, working under pressure P2, where P2≥P1+5 ft/in², regulation of pressure in oxidiser by monitoring opressure in absorber and changing pressure by pressure regulator on exhaust line of oxidiser, oxidation of waste catalyst solution by compressed air in oxidiser with formation of regenerated catalyst solution, separation and removal of solid sulphur from regenerated catalyst solution from oxidiser and removal of regenerated catalyst solution from oxidiser.

EFFECT: effective removal of sulphur from gas flows by redox method under high pressure.
