Hydrocracking, from kinetics to the product slate
Heavy VGO cracked over catalyst by a discrete lumped first-order network, then the standard HP-sep, letdown, LP-sep and fractionator train it feeds.
The actual dark-mode canvas: heavy VGO plus excess hydrogen cracked over catalyst, the H₂-rich gas knocked off at pressure, the liquid let down for a second flash, and what remains fractionated into light naphtha, a kerosene/diesel cut, and unconverted oil.
Kinetics, not a yield table
Each lump cracks at its own Arrhenius rate over a residence time set by LHSV, so raising bed temperature genuinely shifts the product slate. The lump matrix is supplied by you rather than invented by us — a licensor's own network runs here unchanged, and we ship no fabricated one.

Single-stage vapor-liquid equilibrium split at a fixed temperature/pressure.
Isenthalpic Joule-Thomson expansion — the same relation cryogenic JT liquefaction relies on.

Stream reactor bed temperatures, HP-separator pressure, and fractionator draw rates from the unit's OPC-UA server into this flowsheet's twin comparison — a conversion drifting from the solved lump network shows up as a flagged deviation, not a monthly yield surprise.
