Abstract
LA REDUCCION DE LOS EFECTOS DE HISTERESIS EN UN REACTOR DE TRES FASES CON TRANSPORTE NEUMATICO EN BUCLE,ES EFECTUADA CON UN TUBO DE ASPIRACION PARA SOLIDOS EN SUSPENSION.LAS VELOCIDADES DE FLUJO,DE GAS O DE LIQUIDO PARA GENERAR UNA SUSPENSION DE SOLIDOS COMPLETA, SON SIGNIFICATIVAMENTE MAS ALTAS QUE LAS VELOCIDADES DE FLUJO NECESARIAS PARA MANTENER ESE ESTADO.ESTOS EFECTOS DE HISTERESIS PUEDEN SER SIGNIFICATIVAMENTE REDUCIDOS Y SE OBTIENE UNA REDUCCION SUSTANCIAL DE LA ENERGIA NECESARIA PARA CONSEGUIR EL ESTADO DE SUSPENSION. SE USA,PREFERIBLEMENTE,UN TUBO DE ASPIRACION,QUE CONTIENE APERTURAS A TRAVES DE LAS CUALES,TOMA LUGAR UNA CIRCULACION EXTRA ESPECIALMENTE DURANTE LA FASE DE ARRANQUE
