Abstract

Se describe un procedimiento para enfriar una corriente de uno o más componentes, particularmente una fracción rica en hidrocarburos, por medio de un intercambio indirecto de calor con la mezcla de fluidos refrigerantes de un circuito de mezcla de fluidos refrigerantes, siendo la mezcla de fluidos refrigerantes comprimida al menos en dos etapas y separada en una fracción de mezcla de fluidos refrigerantes, de menor punto de ebullición, comprimida a la presión final del circuito de mezcla de fluidos refrigerantes, y en al menos una fracción de mezcla de fluidos refrigerantes, de mayor punto de ebullición, comprimida a una presión intermedia. De acuerdo a la presente, la fracción de mayor punto de ebullición de la mezcla de fluidos refrigerantes es bombeada a la presión de la fracción de menor punto de ebullición de la mezcla de fluidos refrigerantes, y reunida con la fracción de menor punto de ebullición de la mezcla de fluidos refrigerantes por delante o inmediatamente al comienzo del intercambio indirecto de calor.A process for cooling a stream of one or more components, particularly a hydrocarbon-rich fraction, is described by indirect heat exchange with the mixture of refrigerant fluids of a refrigerant fluid mixing circuit, the mixture of refrigerant fluids being compressed at least in two stages and separated into a fraction of mixture of refrigerant fluids, of a lower boiling point, compressed at the final pressure of the circuit of mixture of refrigerant fluids, and in at least a fraction of mixture of refrigerant fluids, of greater boiling point, compressed at an intermediate pressure. Accordingly, the highest boiling fraction of the coolant mixture is pumped at the pressure of the lower boiling fraction of the coolant mixture, and combined with the lowest boiling fraction of the mixture of cooling fluids ahead or immediately at the beginning of indirect heat exchange.
