Abstract

Se proporciona un método para controlar la compresión de una corriente de aire de alimentación entrante a una planta de separación de aire criogénico con el uso de al menos dos unidades de accionamiento directo del compresor de velocidad variable controladas en tándem. La primera unidad de accionamiento directo de velocidad variable impulsa directamente al menos una etapa de compresión en la unidad compresora de menor presión, mientras que la segunda unidad de accionamiento directo de velocidad variable impulsa directamente la etapa de compresión de mayor presión dispuesta en el tren de compresión de aire común de la planta de separación de aire. La primera y la segunda unidad de accionamiento de velocidad variable son, preferentemente, unidades de motor eléctrico de velocidad alta y variable cada una de los cuales tiene un cuerpo de motor, un alojamiento del motor y un vástago del motor con uno o más impulsores acoplados de manera directa y rígida al vástago del motor a través de un acoplamiento de vástago rígido sacrificial.
