| description | processo de preparo de adsorventes sulfetados, adsorventes sulfetados e uso. a presente invenção trata de processo de preparo de adsorventes sulfetados à base de fosfato de cálcio que captura mercúrio em correntes gasosas, compreendendo nas etapas de síntese dos precursores, incorporação de um metal de transição e sulfetação do material. estes adsorventes apresentam elevada eficiência tanto para remoção de mercúrio em baixas concentrações como no gás natural, quanto para a estabilização deste poluente. os adsorventes obtidos na invenção podem ser utilizados nas unidades de recuperação de mercúrio (mrus) presentes nas plantas de processamento do gás natural, cuja unidade de remoção de mercúrio pode ser localizada tanto a montante quanto a jusante das unidades de desidratação e de remoção de h2s, devido aos adsorventes obtidos se mostrarem resistentes ao envenenamento por h2s e manterem seu desempenho na presença de umidade.
The present invention is in relation to a process for preparing calcium phosphate-based sulfated adsorbents that capture mercury in gas streams, comprised of the steps of synthesis of the precursors, incorporation of a transition metal, and sulfation of the material. These adsorbents present high efficiency both for removal of low concentrations of mercury, such as in natural gas, and for stabilization of this pollutant. The adsorbents obtained in the invention may be used in the Mercury Removal Units (MRUs) present in natural gas processing plants, which mercury removal units may be located either upstream or downstream of the dehydration and H2S removal units, due to the adsorbents obtained showing resistance to H2S poisoning, and maintaining their performance in the presence of water. |
