How to remember the refinery process flow sheet in a simple way?
Ans: Well, visualize the refinery into four blocks namely the separation block, the treating block, the reactive transformation block and the rest.
The separation block consists of CDU, VDU, naphtha splitters, C4, C3 and other separators
The treating block consists of all hydrotreaters and gas treating unit
The reactive transformation block consists of thermal cracker (termed as cracking), alkylator, isomerizer and reformer
The last block consists of other units such as blending units, kerosene splitter, n-butane splitter.
This way the refinery can be easily remembered after thoroughly understanding the functional role of each process.
