Abstract
LA ENTRADA DE ENERGIA AL MOTOR DE UN COMPRESOR CENTRIFUGO ACCIONADO ELECTRICAMENTE QUE EMITE UNA VASIJA DE PRESION (12, 14) UTILIZADA PARA SEPARAR COMPONENTES DE UNA MEZCLA GASEOSA (52) MEDIANTE ADSORCION OSCILACION DE PRESION U OSCILACION AL VACIO SE REDUCE EN EL MOMENTO EN EL QUE SE INICIA LA SALIDA PERMITIENDO EL GIRO DE LA RUEDA DEL COMPRESOR PARA DESACELERAR MEDIANTE CONTACTO CON LOS COMPONENTES GASEOSOS ABSORBIDOS HASTA QUE LA VELOCIDAD DE GIRO (B) DE LA RUEDA DEL COMPRESOR COINCIDA CON LA PROPORCION DE COMPRESION EFICAZ DEL COMPRESOR. A CONTINUACION EL MOTOR SE VUELVE A ACTIVAR PARA AUMENTAR LA VELOCIDAD DE GIRO DE LA RUEDA DEL COMPRESOR DE ACUERDO A LA CURVA DE MEJOR EFICACIA PARA DICHO COMPRESOR HASTA QUE SE LOGRE UNA SALIDA COMPLETA PARA LA PROPORCION DE PRESION DE ENTRADA (C) A TRAVES DE DICHO COMPRESOR (60).
