What is the difference between the BMCI value and the aromatic potential content? ? ?

The two concepts are different; the potential aromatic content refers to the amount of aromatics that could theoretically be produced from the reformed oil, and it is used primarily to determine whether such naphtha is a suitable feedstock. The BMCI value is a parameter used for evaluating crude oil, and it is often applied to assess both crude oil and the feedstocks used in steam cracking units to produce ethylene.

A simple formula for calculating aromatic potential is: Aromatic potential = N + 2A, where A is the mass fraction of aromatics in naphtha, and N is the mass fraction of cycloparaffins.

The concepts are different: the aromatic potential content is used for reforming feedstocks, while BMCI is used to evaluate the quality of catalytic cracking feedstocks. There are detailed explanations in the book on petroleum refining
