    Abstract: A system and method for cooling and liquefying a gas in a heat exchanger that includes compressing and cooling a mixed refiigerant using first and last compression and cooling cycles so that high pressure liquid and vapor streams are formed, The high pressure liquid and vapor streams are cooled in the heat exchanger and then expanded so that a primary refrigeration stream is provided in the heat exchanger. The mixed refrigerant is cooled and equilibrated between the first and last compression and cooling cycles so that a pre-cool liquid stream is formed and subcooled in the heat exchanger. The stream is then expanded and passed through the heat exchanger as a pre-cool refrigeration stream. A stream of gas is passed through the heat exchanger in countercurrent heat exchange with the primary refrigeration stream and the pre-cool refrigeration stream so that the gas is cooled.

    Abstract: Un sistema y un método para enfriar y licuar un gas en un intercambiador de calor que incluye comprimir y enfriar un refrigerante mixto usando un primer ciclo de compresion y enfriamiento y un ultimo ciclo de tal manera de formar corrientes de liquido y de vapor a alta presion. Las corrientes de líquido y de vapor a alta presion se enfrían en el intercambiador de calor y luego se expanden de tal manera de suministrar una corriente de refrigeracion primaria al intercambiador de calor. El refrigerante mixto se enfría y equilibra entre el primero y el ultimo ciclo de compresion y enfriamiento de tal manera de formar una corriente de liquido preenfriado que se subenfría en el intercambiador de calor. Luego se expande la corriente y se hace pasar a través del intercambiador de calor como una corriente de refrigeracion preenfriada, Se hace pasar una corriente de gas a través del intercambiador de calor en relacion de intercambio de calor en contracorriente respecto de la corriente de refrigeracion primaria y la corriente de refrigeracion preenfriada de tal manera que el gas se enfría. Una corriente de vapor que se obtiene como resultado, proveniente del pasaje de la corriente de refrigeracion primaria y una corriente de dos fases proveniente del pasaje de la corriente de refrigeracion preenfriada que salen del extremo caliente del intercambiador y se combinan y luego se las somete a una operacion de transferencia simultánea de calor y masa antes del primer ciclo de compresion y enfriamiento de tal manera que al compresor de la primera etapa se le suministra una corriente de vapor a menor temperatura de manera tal de reducir el consumo de energía del sistema. Adicionalmente, casi se cierra el extremo caliente de la curva de enfriamiento, reduciendo más el consumo de energía. Los componentes pesados del refrigerante también se mantienen fuera del extremo frío del proceso, reduciendo la posibilidad de congelacion del refrigerante, y también como facilitando el esquema de gestion del refrigerante.

    Abstract: A system and method for cooling and liquefying a gas in a heat exchanger that includes compressing and cooling a mixed refrigerant using first and last compression and cooling cycles so that high pressure liquid and vapor streams are formed. The high pressure liquid and vapor streams are cooled in the heat exchanger and then expanded so that a primary refrigeration stream is provided in the heat exchanger. The mixed refrigerant is cooled and equilibrated between the first and last compression and cooling cycles so that a pre-cool liquid stream is formed and subcooled in the heat exchanger. The stream is then expanded and passed through the heat exchanger as a pre-cool refrigeration stream. A stream of gas is passed through the heat exchanger in countercurrent heat exchange with the primary refrigeration stream and the pre-cool refrigeration stream so that the gas is cooled. A resulting vapor stream from the primary refrigeration stream passage and a two-phase stream from the pre-cool refrigeration stream passage exit the warm end of the exchanger and are combined and undergo a simultaneous heat and mass transfer operation prior to the first compression and cooling cycle so that a reduced temperature vapor stream is provided to the first stage compressor so as to lower power consumption by the system. Additionally, the warm end of the cooling curve is nearly closed further reducing power consumption. Heavy components of the refrigerant are also kept out of the cold end of the process, reducing the possibility of refrigerant freezing, as well as facilitating a refrigerant management scheme.
