Abstract

PROCEDIMIENTO MEJORADO PARA ENFRIAR Y FLUIDIFICAR UN LECHO DE PARTICULAS.CONSISTENTE EN: A) MEZCLAR UN CRIOGENO LIQUIDO Y UN GAS INERTE QUE ESTA A TEMPERATURA AMBIENTE, EN UN PUNTO EXTERNO DEL LECHO, PERO PROXIMO AL MISMO, PARA PROPORCIONAR UNA MEZCLA DE CRIOGENO LIQUIDO Y GAS A TEMPERATURA BAJA, PARA MANTENER EL LECHO A LA TEMPERATURA DE FUNCIONAMIENTO DESEADA; B) INTRODUCIR LA MEZCLA PROCEDENTE DE LA ETAPA (A) EN DOS SERPENTINES DE TRANSFERENCIA DE CALOR CONECTADOS EN PARALELO Y SITUADOS EN EL LECHO, PARA COMUNICAR AL LECHO LA TEMPERATURA DE FUNCIONAMIENTO DESEADA Y VAPORIZAR AL CRIOGENO LIQUIDO DE LA MEZCLA; Y C) RETIRAR LA MEZCLA DE CRIOGENO LIQUIDO VAPORIZADO Y GAS FORMADA EN LA ETAPA (B), DESDE LOS SERPENTINES E INTRODUCIR LA MEZCLA EN EL LECHO PARA FLUIDIFICAR EL LECHO.
