PROCEDIMENTO DI TRATTAMENTO DI CORRENTI GASSOSE O LIQUIDE DI COMPOSTI DI ALOGENI |
摘要 |
<p>Halogen containing chemicals are removed from a liquid hydrocarbon stream by a solid non-regenerative adsorbent in a treating zone. When the adsorbent becomes incapable of treating the liquid stream, it is used to treat a gaseous stream to remove halogens. A sequential switching of the liquid and gaseous streams provides continuous operation with fixed beds of adsorbent. The preferred embodiment encompasses a moving-bed process in which fresh alumina removes a boron oxide hydrate complex from a liquid aromatic hydrocarbon stream and the resulting unregenerable used alumina then treats an off-gas stream of the process to remove fluorine.</p> |
