摘要： Hydrocarbon feedstock containing resid is cracked by a process comprising: (a) heating the hydrocarbon feedstock; (b) mixing the heated hydrocarbon feedstock with steam and optionally water to form a mixture stream; (c) introducing the mixture stream to a flash/separation apparatus to form i) a vapor phase at its dew point which partially cracks and loses/or heat causing a temperature decrease and partial condensation of the vapor phase in the absence of added heat to provide coke precursors existing as uncoalesced condensate, and ii) a liquid phase; (d) removing the vapor phase as overhead and the liquid phase as bottoms from the flash/separation apparatus; (e) treating the overhead by contacting with a hydrocarbon-containing nucleating liquid substantially free of resid and comprising components boiling at a temperature of at least about 260° C. (500° F.) under conditions sufficient to at least partially coalesce the coke precursors to provide coke precursor liquid, in the form of hydrocarbon droplets or a continuous hydrocarbon liquid phase; (f) collecting and removing the droplets; (g) directing the treated overhead from which the droplets are removed, to a heater to provide a heated vapor phase; (h) cracking the heated vapor phase in a radiant section of a pyrolysis furnace to produce an effluent comprising olefins, the pyrolysis furnace comprising a radiant section and a convection section; and (i) quenching the effluent and recovering cracked product therefrom. An apparatus for carrying out the process is also provided.

摘要： A process for decoking of a process that cracks hydrocarbon feedstock containing resid and coke precursors, wherein steam is added to the feedstock to form a mixture which is thereafter separated into a vapor phase and a liquid phase by flashing in a flash/separation vessel, separating and cracking the vapor phase, and recovering cracked product. Coking of internal surfaces in and proximally downstream of the vessel is controlled by interrupting the feed flow, purging the vessel with steam, introducing an air/steam mixture to at least partially combust the coke, and resuming the feed flow when sufficient coke has been removed. An apparatus for carrying out the process is also provided.

摘要： A novel outlet fitting for use in connection with a heat exchanger. The heat exchanger is used in the role of a quench exchanger for cooling cracking effluent and solves particular problems associated with gas-oil cracking applications and other heavy feed based applications wherein differences between process outlet temperature and coolant temperatures are larger than in, for example, naphtha and gas cracking applications. The specific solution is achieved through a novel outlet fitting for the quench exchanger that eliminates the need for a steam purge, addresses thermal stress issues and reduces pressure drop within the system. The outlet fitting includes internal insulation to avoid the need for a steam purge. In addition, the outlet fitting includes a low-angle diffuser with an angle of less than 7 degrees and preferably less than 5 degrees.

Coking of internal surfaces in and proximally downstream of the vessel is controlled by interrupting the feed flow, purging the vessel with steam, introducing an air/steam mixture to at least partially combust the coke, and resuming the feed flow when sufficient coke has been removed.
