Application examples

This example presents the ammonia synthesis process from natural gas. This example includes two simulations: one simulation is dedicated to the entire process and another to the reactor alone to take into account its technological specificities. A pinch analysis of the process is also carried out.

This example corresponds to the simulation of a manufacturing unit of nitric acid by a dual-pressure process. It is a rather traditional process of industrial production of nitric acid. The main modules specific to the simulator ProSimPlus HNO3 are implemented here: absorption column of nitrous vapors, nitrous vapors condensers, oxidation reactors, heat exchangers with oxidation volumes, nitrous vapor compressors, etc.

This example illustrates the simulation of a manufacturing unit of nitric acid by a monopressure process. It is also a rather traditional process of nitric acid industrial production. The main modules specific to the simulator ProSimPlus HNO3 are implemented here: absorption column of nitrous vapors, nitrous vapors condensers, oxidation reactors, heat exchangers with oxidation volumes, nitrous vapor compressors, etc.

This example uses a column with two packing beds to absorb the NOx of a gas stream with a weak solution of nitric acid. The flow rate of this solution is determined to respect the NOx content of the gas stream leaving the column.
