摘要： A process for synthesis of ammonia including generation of makeup gas in a frontend and conversion of said makeup gas in an ammonia synthesis loop including a circulator, a converter, a condensation section and a liquid ammonia separation section, including: when the loop operates at a partial load and a flow rate of makeup gas transferred from the front end to the synthesis loop is reduced, the loop is controlled by separating a gas stream from a converter feed line at a point upstream of the converter thus forming a bypass stream; reintroducing said bypass stream at the suction side of the circulator or at a point of the loop downstream of said separation section.
