Abstract

UN PROCESO PARA ENFRIAR O SOMETER A LICUEFACCIÓN UNA CORRIENTE RICA EN L'IIDROCARBUROS, POR EJEMPLO UNA CORRIENTE DE GAS NATURAL, EN PLANTAS DE FLOTACION LUN, EN DONDE EL ENFRIADO O LICUEFACCIÓN DE LA CORRIENTE RICA EN HIDROCARBUROS PROCEDE EN CONTRA DE UN CICLO REFRIGERANTE MISTO, EN DONDE EL REFRIGERANTE MIXTO ESTÁ SUJETO A COMPRESIÓN, ESTANDO PRESENTE A LO MENOS EN PARTEEN FORMA CONDENSADA DENTRO DEL CICLO REFRIGERANTE MIXTO YEN TODOS LOS ESTADOS DEL PROCESO, EN PARTICULAR EN LA SUCCIÓN DEL COMPRESOR TIENE UNA DENSIDAD MOLAR DE A LO MENOS 0,30 KMOL/M3, DE PREFERENCIA A LO MENOS 0,35 KMOL/M3, YEN DONDE LA COMPRESIÓN DEL REFRIGERANTE MIXTO, PROCEDE POR MEDIO DE UN COMPRESOR DE EJE SIMPLE QUE TIENE UNA CARCASA VERTICAL DIVIDIDA.A PROCESS TO COOL OR SUBMIT TO LIQUEFACTION A CURRENT RICH IN HYDROCARBONS, FOR EXAMPLE A CURRENT OF NATURAL GAS, IN LUN FLOATING PLANTS, WHERE THE COOLING OR LICUFACTION OF THE RICH CURRENT IN HYDROCARBON-REFURBISHED MERGER WHERE THE MIXED REFRIGERANT IS SUBJECT TO COMPRESSION, IT IS PRESENT AT LEAST IN PART IN A CONDENSED FORM WITHIN THE MIXED REFRIGERANT CYCLE AND IN ALL PROCESS STATES, IN PARTICULAR IN THE COMPRESSOR SUCTION IT HAS A LESS MOLAR DENSITY OF 0.30 KMOL / M3, PREFERABLY AT LEAST 0.35 KMOL / M3, AND WHERE THE COMPRESSION OF THE MIXED REFRIGERANT, COMES THROUGH A SINGLE SHAFT COMPRESSOR THAT HAS A SPLIT VERTICAL CASE.
