Generally includes the processes linked to the production of chemical compounds used on an industrial scale. Such processes consist of combinations of unit operations (reactions, exchange of mass, heat and momentum) that are carried out in specific equipment (reactors, columns, exchangers, separators, compressors, pumps, valves and pipes). The separators in particular are widely used in all of these processes, whenever it is necessary to separate liquid entrainments from a vapour phase or liquid entrainments dispersed in another liquid phase that is immiscible with the first.
