Naphtha-Mogas pool optimization Utilisation options for naphtha
Naphtha components
Steam Cracking prefers paraffinic low boiling point naphtha Quality measured by: monomer yields
Reforming prefers aromatic naphthenic naphtha Quality measured by: Reformate RON, MON = f(N+2A)
Some naphtha may go to Diesel / Kero pool: paraffinic higher boiling point naphtha
components
8
Reforming economics is determined by feed N+2A
Reforming prefers aromatic and naphthenic naphtha
Higher reformer feed N+2A
Higher reformate RON and MON
Better reformer economics
Aromatics: B,T, X,
Naphthenics: Cyclo-paraffins
9
How to calculate SC economics as a function of naphtha quality ?
Steam Cracking prefers paraffinic (iso and n-paraffins) low boiling point naphtha
Normal paraffins Isoparaffins
Steam Cracker margin is determined by the monomer yields.
Which naphtha parameter correlates best with Steam Cracker yields?
Candidates:
- Density
- Boiling points - IBP - T50 - FBP (T95)
- Group composition - Isoparaffin - n-paraffin - aromatics - naphthenic
- Combinations of the above parameters

Start up and use new model
Target Improved Naphtha pool optimisation based on Steam Cracker economics calculated
from expected product yields Consistent handling of own produced and external naphtha components Implementation steps
11
Step 1: Concept
An internal MOL Lean study statement:
Less aromatic naphtha Higher Petchem profitability
Source: MOL internal Lean study: L. Szirmai, M. Bublik, G. Grdonyi, Sz. Simon
12
Step 2: Data acquisition
Naphtha stream lists, sampling points
Laboratory analyses Data preparation
Danube Refinery naphtha streams DCDU3 Light NAPHTHA DCDU2 Light NAPHTHA DCDU1 light Naphtha
Slovnaft naphtha streams Heavy naphtha from BADU5 Heavy naphtha from BCDU6 Heavy naphtha from SPL C5/C6 fraction from AD 5
Import naphthas Source A Source B
Naphtha tank data Refinery tanks Petchem site tanks
Density
Boiling points IBP T50 FBP (T95)
Group composition Isoparaffin n-paraffin aromatics naphthenic
Yearly averages for main streams in naphtha pool
Define typical naphtha compositions for each petchem site

SPYRO yields for each steam cracker and each naphtha component
Expected once-through product yields for each steam cracker and each naphtha component
SC-1 yields Naphtha stream A Naphtha stream B
SC-2 yields Naphtha stream A Naphtha stream B
Grouping of individual components to real components
Apply empirical corrections, simplifications
