VERFAHREN ZUR DESULFURIERUNG VON GASFOERMIGEN EFFLUENTEN |
摘要 |
A gaseous stream comprising a substantial quantity of sulphur compounds such as SO2, SO3 and/or H2S is desulphurized by (a) introducing, at a first end of an absorption zone 21, particles of an absorbent mass comprising at least one zeolite in a matrix, magnesium oxide, nickel oxide, iron oxide and vanadium oxide the absorbent mass having a grain size distribution between 5 and 5000 micrometres and a specific surface between 0.1 and 500 m<2>/g; (b) the introduction of the gaseous stream at a temperature between approximately 400 and 1000 DEG C at said 22 of the absorption zone in such a way that the surface velocity in the absorption zone is between 0.3 to 40 m/s; (c) the contacting, in the flowing fluidized bed, of the gaseous stream and said particles in the presence of an oxygen- containing gas under absorption conditions such that the sulphur content of said gaseous stream is reduced and a mixture is obtained of particles enriched with the sulphate of the metal introduced in stage (a) and sulphur-depleted gaseous effluent; (d) the at least partial separation of said sulphate-enriched particles from said sulphur-depleted gaseous effluent in a separation zone at the opposite end of the absorption zone; and (e) the recovery of the first gaseous effluent having a reduced sulphur content; and the sulphur-enriched absorbent is regenerated. <IMAGE>
