Abstract

DEPOSITOS DE COQUE QUE SON ELIMINADOS DE MICROPARTICULAS POR LA COMBUSTION EN UN REGENERADOR (4) MEDIANTE UN PROCESO EN EL QUE EL AIRE SE UTILIZA INICIALMENTE COMO OXIDANTE. EL GAS DE COMBUSTION ES SOMETIDO A UN PROCESO DE SEPARACION EN UN SEPARADOR (6) PARA EXTRAER EL NITROGENO DEL MISMO, Y EL FLUJO DE GAS DE DIOXIDO DE CARBONO ENRIQUECIDO RESTANTE, SE RECICLA EN EL REGENERADOR (4) MIENTRAS SE INTRODUCE OXIGENO SUSTANCIALMENTE PURO EN EL REGENERADOR. AL INCREMENTARSE EL NIVEL DE DIOXIDO DE CARBONO EN EL SISTEMA, LA CANTIDAD DE AIRE QUE SE INTRODUCE EN EL REGENERADOR (4) SE REDUCE GRADUALMENTE, Y EN COMPENSACION, LA CANTIDAD DE OXIGENO QUE FLUYE AL REGENERADOR SE INCREMENTA GRADUALMENTE. EVENTUALMENTE, PARTE O TODO EL AIRE ES SUSTITUIDO POR OXIGENO Y GAS DE RECICLAJE DE DIOXIDO DE CARBONO, Y LOS NIVELES DE OXIGENO Y DE DIOXIDO DE CARBONO, SE REDUCEN PARA MANTENER LA TEMPERATURA DESEADA EN EL REGENERADOR (4).
