METHOD FOR DECREASING AN AMOUNT OF A HARMFUL SUBSTANCE OF AN OFF-GAS STREAM FORMED OR USED IN A THERMAL TREATMENT OF A MATERIAL |
| 摘要 |
A method for decreasing an amount of a harmful substance of a chlorine-containing off-gas stream formed or used in a thermal treatment of a material may comprise dividing the chlorine-containing off-gas stream into a main stream and a substream, separating at least some chlorine from the main stream, lowering an amount of the harmful substance in the main stream by introducing a chlorine-containing additive into the main stream to enhance separation of the harmful substance, and filtering the substream such that a filter cake separated from the substream comprises at least part of the chlorine-containing additive. |
