Steam cracking, from furnace to C2 splitter
Ethane cracked to ethylene at real furnace-conditions equilibrium, then separated from unconverted ethane in a genuinely high-reflux column.
The actual dark-mode canvas: ethane cracked to ethylene at furnace conditions, quenched and compressed, then split from unconverted ethane in a high-reflux C2 splitter — the same P&ID symbols you edit in the app.
Furnace equilibrium and a real C2 splitter
The cracking extent comes from real chemical equilibrium at furnace conditions, and the C2 splitter is a full MESH column — ethylene/ethane relative volatility is modest, so it genuinely needs the many stages and high reflux this column runs.
