Abstract

Un proceso para la sintesis de amoniaco, el cual incluye la produccion de gas de compensacion en un extremo delantero y la conversion de dicho gas de compensacion en un circuito (5) de sintesis de amoniaco que incluye un dispositivo (6) de circulacion, un convertidor (7), una seccion de condensacion (8) y una seccion (9) de separacionde amoniaco liquido, incluyendo: cuando el circuito operaa una carga parcial y se encuentra reducido un caudal de flujo del gas de compensacion transferido desde el extremo delantero hacia el circuito de sintesis, se controlaal circuito mediante la separacion de una corriente gaseosa desde un conducto de alimentacion (10) del convertidor, en un punto en corriente ascendente del convertidor (7), para formar asi una corriente de derivacion(15); la reintroduccion de dicha corriente de derivacion en el lado de succion (24) del dispositivo de circulacion (6) o en un punto del circuito (5) en corriente descendente de dicha seccion (9) de separacion.
