WERKWIJZE VOOR DE BEREIDING VAN ZWAVEL UIT TWEE ZURE ZWAVELWATERSTOFBEVATTENDE GASSEN, WAARVAN EEN AMMONIAK BEVAT. |
摘要 |
<p>A process to produce sulphur from two acid gases both containing hydrogen sulphide and one of which contains ammonia, using a modified Claus technique. The acid gas containing ammonia is burnt in the presence of air under substoichiometric conditions in a first heat-reaction chamber, while the ammonia-free acid gas is burnt in a second heat-reaction chamber, forming a series with the first chamber, with the right quantity of air to provide a molar ratio of H2S to SO2 of approximately 2/1 at the catalytic reaction stage inlet. The mixed effluents from both heat-reaction chambers may pass through a high-temperature residence chamber before being conveyed to the heat-recovery stage. Gas effluents from the heat-reaction stage contain H2S and SO2 in the right ratio for the catalytic reaction stage, and no hydrocarbons or harmful quantities of NH3 and NO.</p> |
