Abstract
The invention relates a process for removing coke formed during steam-cracking of a hydrocarbon feed. The process includes providing a decoking feed to at least one radiant coil of a steam-cracking furnace under conditions to remove at least a portion of coke from the at least one radiant coil to form a decoking effluent. The decoking effluent is cooled with a liquid quench medium to provide an partially-quenched decoking effluent. The partially-quenched decoking effluent is cooled with a gaseous quench medium to provide a quenched effluent. An apparatus configured to perform such a process is also described.
