    Abstract: REFERIDO A UN SISTEMA Y METODO PARA ENFRIAR Y LICUAR UN GAS EN UN INTERCAMBIADOR DE CALOR QUE INCLUYE COMPRIMIR Y ENFRIAR UN REFRIGERANTE MIXTO UTILIZANDO UN PRIMER Y ULTIMO CICLOS DE COMPRESION Y ENFRIADO DE MODO QUE SE FORMEN CORRIENTES DE LIQUIDO Y VAPOR A ALTA PRESION. LAS CORRIENTES DE LIQUIDO Y VAPOR A ALTA PRESION SON ENFRIADAS EN EL INTERCAMBIADOR DE CALOR Y LUEGO EXPANDIDAS DE MODO QUE UNA CORRIENTE DE REFRIGERACION PRIMARIA ES SUMINISTRADA EN EL INTERCAMBIADOR DE CALOR. EL REFRIGERANTE MIXTO ES ENFRIADO Y EQUILIBRADO ENTRE EL PRIMER Y ULTIMO CICLOS DE COMPRESION Y ENFRIADO DE MODO QUE UNA CORRIENTE DE LIQUIDO PRE-ENFRIADO SE FORME Y SE SUB-ENFRIE EN EL INTERCAMBIADOR DE CALOR. LA CORRIENTE ES LUEGO EXPANDIDA Y PASADA A TRAVES DEL INTERCAMBIADOR DE CALOR COMO UNA CORRIENTE DE REFRIGERACION PRE-ENFRIADA. UNA CORRIENTE DE GAS ES PASADA A TRAVES DEL INTERCAMBIADOR DE CALOR EN CONTRACORRIENTE CON LA CORRIENTE DE REFRIGERACION PRIMARIA Y LA CORRIENTE DE REFRIGERACION PRE-ENFRIADA DE MODO QUE EL GAS SE ENFRIE

    Abstract: sistema e método de refrigerante misturado pré-resfriado integrado. a invenção refere-se a um sistema e método para resfriar e liquefazer um gás em um trocador de calor que inclui comprimir e resfriar um refrigerante misturado utilizando um primeiro e último ciclos de compressão e de resfriamento de modo que fluxos de líquidos e de vapor de alta pressão sejam formados. os fluxos de líquido e de vapor de alta pressão são resfriados no trocador de calor e então expandidos de modo que um fluxo de refrigeração primário seja provido no trocador de calor. o refrigerante misturado é resfriado e equilibrado entre os primeiro e último ciclos de compressão e de resfriamento de modo que um fluxo de líquido de pré-resfriamento seja formado e subresfriado no trocador de calor. o fluxo é então expandido e passado através do trocador de calor como um fluxo de refrigeração de pré-resfriamento. um fluxo de gás é passado através do trocador de calor em troca de calor de contracorrente com fluxo de refrigeração primário e o fluxo de refrigeração de pré-resfriamento de modo que o gás seja resfriado.

    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: 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.
