Abstract: A process for synthesis of ammonia wherein an ammonia synthesis loop includes an ammonia converter where a makeup gas is reacted to form ammonia, and the loop is controlled at a partial load by reducing the synthesis pressure and maintaining the reduced pressure within a desired range by controlling a bypass line of make-up gas of the converter.

Abstract: A reactor system comprising a multibed catalytic converter including a mixing region upstream of a catalytic bed, the mixing region is arranged to mix a feed gas of the catalytic bed with a mixing gas, the mixing gas is introduced in the mixing region via a plurality of mixing gas feed lines, each of said lines includes at least one flow regulators device so that the amount of mixing gas admitted into the mixing region by each of the mixing gas feed lines is independently controlled.
