Abstract

REFERIDO A UN PROCESO PARA LA DESNITROGENACION DE UNA ALIMENTACION DE GAS NATURAL LICUADO, EL CUAL CONTIENE 1-10 MOLES POR CIENTO DE NITROGENO, QUE COMPRENDE: A) EXPANDIR A LA CORRIENTE DE ALIMENTACION DE GAS NATURAL LICUADO A TRAVES DE MEDIOS DISPUESTOS PARA EXPANDIR A DICHA CORRIENTE Y ENFRIARLA EN UN PERMUTADOR TERMICO CON CALDERA; B) INTRODUCIR A LA CORRIENTE DE GAS NATURAL LICUADO ENFRIADO Y EXPANDIDO HACIA UNA COLUMNA DE ELIMINACION DE NITROGENO; C) RETIRAR UNA CORRIENTE DE VAPOR DE LA PARTE SUPERIOR DESDE LA COLUMNA; D) RETIRAR UNA CORRIENTE LIQUIDA RESIDUAL DESDE LA COLUMNA; E) HACER PASAR A LA CORRIENTE RESIDUAL DESDE LA ETAPA (D) A TRAVES DE UNA BOMBA PARA AUMENTAR LA PRESION DE LA CORRIENTE LIQUIDA RESIDUAL; F) DIVIDIR A LA CORRIENTE RESIDUAL EN UNA PRIMERA CORRIENTE Y UNA SEGUNDA CORRIENTE; G) VAPORIZAR POR LO MENOS PARCIALMENTE A LA SEGUNDA CORRIENTE MEDIANTE LA REDUCCION DE PRESION DE ESTA ULTIMA Y HACIENDOLA PASAR LUEGO A TRAVES DEL PERMUTADOR TERMICO CON CALDERA DE LA ETAPA (A); Y H) INYECTAR A LA SEGUNDA CORRIENTE PARCIALMENTE VAPORIZADA DE LA ETAPA (G) A LA COLUMNAREFERRED TO A PROCESS FOR THE DENITROGENATION OF A LIQUEFIED NATURAL GAS SUPPLY, WHICH CONTAINS 1-10 MOLS PER PERCENT OF NITROGEN, WHICH INCLUDES: A) EXPANDING THE SUPPLY CURRENT OF NATURAL GAS TO DISPOSE OF THROUGH LIQUEFIED MEDIA. SAID CURRENT AND COOL IT IN A THERMAL SWAP WITH BOILER; B) INTRODUCE THE LIQUEFIED AND EXPANDED LIQUEFIED NATURAL GAS CURRENT TO A NITROGEN ELIMINATION COLUMN; C) REMOVE A STREAM OF VAPOR FROM THE UPPER PART FROM THE COLUMN; D) REMOVE A RESIDUAL LIQUID CURRENT FROM THE COLUMN; E) MAKE THE RESIDUAL CURRENT PASS FROM STAGE (D) THROUGH A PUMP TO INCREASE THE PRESSURE OF THE RESIDUAL LIQUID CURRENT; F) DIVIDE THE RESIDUAL CURRENT INTO A FIRST CURRENT AND A SECOND CURRENT; G) VAPORIZE AT LEAST PARTIALLY THE SECOND CURRENT BY REDUCING THE PRESSURE OF THE SECOND CURRENT AND THEN MAKING IT PASS THROUGH THE THERMAL SWITCH WITH BOILER OF STAGE (A); AND H) INJECTING THE SECOND PARTIALLY VAPORIZED CURRENT FROM STAGE (G) TO THE COLUMN
