Naphtha steam cracker: furnace, quench, compression, cryo train
The full ethylene-plant process shape (steam-methane-cracking's headline technology, e.g. Linde's steam cracking line): a fired-heater convection preheat, a three-reactor lumped pyrolysis furnace, a transfer-line-exchanger quench, a primary fractionator pulling off pyrolysis gasoline, two-stage compression with interstage knockouts, selective acetylene hydrogenation, and a cryogenic cold train (cold-flash light-gas rejection, deethanizer, C₂ splitter, depropanizer) delivering four real products — ethylene, propylene, a butadiene-rich C₄ cut, and a pygas/heavy-ends byproduct — plus an H₂/CH₄-rich tail gas and two knockout condensate streams.

The other real use of cracked-gas acetylene: instead of being hydrogenated away as a trace impurity (see naphtha-steam-cracker's ACETYLENE_HYDRO step and patent-c3-selective-hydrogenation), acetylene is deliberately RECOVERED as product when present at high enough concentration — industrially via selective solvent absorption (DMF or NMP preferentially dissolve acetylene over the other light hydrocarbons), then stripped back out to release a pure acetylene stream.
