Abstract

é divulgado um método para operar uma unidade de compressor (2) compreendendo um ou mais compressores (8, 9, 10), a unidade de compressor (2) estando disposta em um sistema de compressão a vapor (1). são definidas duas ou mais opções para distribuir a capacidade de compressor disponível da unidade de compressor (2) entre ser conectada a uma linha de sucção de alta pressão (11) e a uma linha de sucção de pressão média (13). para cada opção prevê-se um impacto esperado em um ou mais parâmetros operacionais do sistema de compressão a vapor (1), resultante da distribuição da capacidade de compressor disponível conforme a opção. é selecionada uma opção com base no impacto esperado previsto para as opções, e com base nas demandas operacionais atuais do sistema de compressão a vapor (1), e a capacidade de compressor disponível é distribuída conforme a opção selecionada, por exemplo, por meio de configurações de um ou mais arranjos de válvula (14, 15).
