Ethylene oxide to glycol, with a real competing side reaction
Ethylene and oxygen reacted over competing epoxidation and combustion pathways, condensed, hydrated, and distilled to monoethylene glycol.
The actual dark-mode canvas: ethylene and oxygen reacted over two competing pathways, EO condensed from the vent gas, hydrated to glycol, and recovered by distillation — the same P&ID symbols you edit in the app.
A real competing side reaction, not idealized selectivity
Low per-pass ethylene conversion (~10%) is realistic — pushing conversion higher would push the competing total-combustion side reaction, modeled here as its own reactor consuming a fixed share of the same ethylene at ~80% EO selectivity, not asserted as a single clean yield.
