Title (EN) PROCESS FOR TREATING FLUE GASES IN CDS FLUE GAS TREATMENT
(FR) PROCÉDÉ DE TRAITEMENT DE GAZ DE COMBUSTION DANS UN TRAITEMENT DE GAZ DE COMBUSTION À ÉPURATEUR À SEC À LIT CIRCULANT (CDS)
Abstract:
(EN) Process for treating flue gases in a circulating dry scrubber device wherein flue gases containing pollutants pass to a reactor where said flue gases contact a sorbent comprising high pore volume and high specific surface area slaked lime or hydrated lime being further sent to a particulate control device where said sorbent particles are separated from said flue gases substantially depleted in pollutants and form respectively a flow of flue gases substantially depleted in pollutants and a flow of sorbent particles being recycled and returned to said reactor.
(FR) Un procédé de traitement de gaz de combustion dans un épurateur à sec à lit circulant dans lequel des gaz de combustion contenant des polluants passent dans un réacteur où ils entrent en contact avec un sorbant possédant un volume poreux élevé et de la chaux éteinte à surface spécifique élevée ou de la chaux hydratée; ils sont ensuite envoyés à un dispositif de contrôle de particules dans lequel lesdites particules sorbantes sont séparées desdits gaz de combustion sensiblement appauvris en polluants et forment respectivement un flux de gaz de combustion sensiblement appauvri en polluants et un flux de particules sorbantes qui est recyclé et renvoyé audit réacteur.
