Abstract
Se describe un método de compresión, un sistema de compresión de múltiples etapas y un método y una planta en los cuales un gas se comprime en una serie de etapas de compresión para producir un gas comprimido y cada una de las etapas de compresión incorpora un compresor de velocidad variable. En tal método y sistema de compresión, el aire comprimido se produce a una presión que permanece estable durante las condiciones operacionales normales y durante las condiciones de desaceleración durante las cuales se reduce la velocidad de flujo del gas. Esta reducción se logra al reducir la velocidad del compresor en una etapa de compresión inicial de tal manera que el compresor opere en un punto a lo largo de su línea de operación de eficacia máxima en la cual la relación de presión es directamente proporcional a la velocidad de flujo y de tal manera que la menor velocidad de flujo reducida se obtenga a una presión reducida que se forma en las etapas de compresión sucesivas.
