| A method for producing ammonia may be provided. The method may include supplying ammonia synthesis gas to a synthesis gas screw compressor and compressing the synthesis gas. The compressed synthesis gas may be joined with a flow of recycle gas compressed in a recycle gas screw compressor. The compressed combined flow may then be introduced to an ammonia reactor. The ammonia reactor may discharge ammonia, purge gas, and unconverted gas, which may be the recycle gas. | ||||||

| The present invention relates to a pumping method in a pumping system (SP) comprising: a primary dry screw-type vacuum pump (3) with a gas entry orifice (2) connected to a vacuum chamber (1) and a gas exit orifice (4) leading into a conduit (5) before coming out into the gas outlet (8) of the pumping system (SP), a non-return valve (6) positioned in the conduit (5) between the gas exit orifice (4) and the gas outlet (8), and an ejector (7) connected in parallel to the non-return valve (6). According to this method, the primary dry screw-type vacuum pump (3) is put into operation in order to pump the gases contained in the vacuum chamber (1) through the gas exit orifice (4); in a simultaneous way, the ejector (7) is fed with working fluid, and the ejector (7) continues to be fed with working fluid all the time that the primary dry screw-type vacuum pump (3) pumps the gases contained in the vacuum chamber (1) and/or all the time that the primary dry screw-type vacuum pump (3) maintains a defined pressure in the vacuum chamber (1). The present invention also relates to a pumping system (SP) able to be used for implementing this method. | ||||||
