Abstract
método de comprimir um gás, método de separar ar, sistema de compressão de múltiplos estágios para comprimir um gás, e, instalação de separação de ar um método de compressão, um sistema de compressão em múltiplos estágios e um método ei uma instalação de separação de ar em que um gás é comprimido em uma série de estágios de compressão e cada um dos estágios de compressão incorpora um compressor de velocidade variável. em tais método e sistema de compressão, o ar comprimido é produzido em uma pressão que permanece estável tanto durante as condições de operação normais quanto durante condições de desaceleração durante as quais a vazão do gás é reduzida. esta redução é obtida reduzindo a velocidade do compressor em um estágio de compressão inicial de tal modo que o compressor opera em um ponto ao longo de sua linha de operação de eficiência de pico em que a razão de pressão é diretamente proporcional à vazão e de tal forma que a razão de desaceleração inferior é obtida a uma pressão reduzida que é constituída em estágios de compressão sucessivas.method of compressing a gas, method of separating air, multistage compression system for compressing a gas, and, air separation installation, a compression method, a multistage compression system, and a method i and a air in which a gas is compressed in a series of compression stages and each compression stage incorporates a variable speed compressor. In such a method and compression system, compressed air is produced at a pressure that remains stable both under normal operating conditions and during deceleration conditions during which gas flow is reduced. This reduction is achieved by reducing the speed of the compressor at an initial compression stage such that the compressor operates at a point along its peak efficiency operating line where the pressure ratio is directly proportional to flow and such. This means that the lower deceleration ratio is obtained at a reduced pressure which is constituted by successive compression stages.
