For a standard process, there are several licensors like UOP, Axens, Lummus, etc. & they are responsible for developing the PFD. Process flow diagrams of open art process units like CDU (Crude distillation unit), and VDU (vacuum distillation unit) can be found in the literature and encyclopedia of chemical technology.

The Following flow chart shows a process of producing iron by reducing Fe 3 O 4 .The reactions are- Fe 3 O 4 + H 2 FeO + H 2 → 3 FeO + H 2 O → Fe + H 2 O Two reactors are needed due to the nature of the reactions. Both of the reactions occur in the Reactor -1 . However, only the second reaction occurs in the Reactor-2.

Abstract The author investigated the modes of thermal and heat-and-radiation treatment of ferruginous bauxite from Vezhayu–Vorykva deposit and revealed different mechanisms of mineral transformations. Under thermal treatment, oxo-hydroxides transform into anhydrous iron and aluminum oxides, while under heat-and-radiation …
