Schemes comprising partial oxidation with oxygen

The sequence of operations concerned in this case is as follows (Fig. 1.14ai  

This operation (Fig. 1.15), which is specific to the use of hydrogen produced for ammonia synthesis, is similar in principle to the one used to separate carbon monoxide by scrubbing mth liquid methane (see S on 1.2.3.2). Its value is therefore twofold  

Among the adaptations made to the liquid methane scrubbing scheme is the replacement of the carbon monoxide refrigeration cycle by a similar system operating with nitrogen. 

If a conversion of this type is carried out, the series of operating sequences is as follows (diagram b in Fig. 1.14)
