Abstract
A system and method including providing a feed having alkyl-bridged multi-aromatic compounds to a tubular reactor, heating the tubular reactor, and cleaving an alkyl bridge of the alkyl-bridged multi-aromatic compounds.
Claims11
A hydrodearylation reactor system comprising:
- a feed conduit operationally coupled to an aromatics complex to receive a hydrocarbon feed comprising alkyl-bridged multi-aromatic compounds, the aromatics complex comprising a distillation column;
- a coiled tubular reactor operationally coupled to the feed conduit to receive the hydrocarbon feed and to cleave an alkyl bridge of an alkyl-bridged multi-aromatic compound of the alkyl-bridge multi-aromatic compounds in presence of hydrogen;
- a hydrogen conduit to add hydrogen to the feed conduit or directly to the coiled tubular reactor;
- a furnace to heat the coiled tubular reactor;
- a discharge conduit to discharge an effluent from the coiled tubular reactor;
- and
- a heat exchanger to heat the hydrocarbon feed with the effluent.

The system of 37, wherein the feed conduit is operationally coupled to the separation system to receive C10+ components from the separation system.
A hydrodearylation reactor system comprising:
- a feed conduit operationally coupled to an aromatics complex to receive hydrocarbon feed comprising aromatic compounds comprising alkyl-bridged multi-aromatic compounds from the aromatics complex, the aromatics complex comprising a distillation column;
- a first coiled tubular reactor operationally coupled to the feed conduit to receive the aromatic compounds and to cleave an alkyl bridge of an alkyl-bridged multi-aromatic compound in presence of hydrogen;
- a first hydrogen conduit to add hydrogen to the feed conduit or directly to the first coiled tubular reactor;
- a first furnace to heat contents of the first coiled tubular reactor to a temperature in a range of 450° C. to 600° C.;
- a first discharge conduit to discharge a first effluent from the first coiled tubular reactor to a second coiled tubular reactor;
- the second coiled tubular reactor to perform hydrodealkylation on aromatic compounds in the second coiled tubular reactor;
- and
- a second furnace to heat contents of the second coiled tubular reactor to a temperature of greater than 600° C.
