摘要： A FCC product recovery section operates at greater efficiency by recovering separate riser product streams and reactor product streams and quenching and absorbing lighter, more valuable hydrocarbon products from the reactor product stream in separate quench and absorption vessels. The quench and absorbtion vessels are intergrated with a main fractionator and gas concentration section of a typical FCC product recovery section. Heavy hydrocarbons, clarified oil and/or cycle oil absorb hydrocarbons from the reactor product stream in the quench and absorption vessels and return the absorbed products to the main fractionator while net gasoline product from the reactor product stream enter the primary absorber of the gas concentration section. This arrangement is particularly useful in increasing the product recovery capacity of an existing FCC product separation section.

摘要： An FCC apparatus uses a highly efficient separation device to remove product from the catalyst so that the reactor vessel receives a low volume of feed hydrocarbons and riser by-products. The separation device encloses an upwardly directed outlet end of a ballistic separation device in low volume disengaging vessel that collects disengaged catalyst from the riser in a dense bed. Immediate contact of the dense bed with a stripping fluid minimizes the amount of hydrocarbons that are carried out of the disengaging vessel into the open volume of the reactor vessel.

摘要： An FCC process and apparatus is arranged to provide a low volume dilute disengagement zone in a reactor vessel and a quench zone immediately downstream of the reactor vessel. A vented riser that provides an open discharge of catalyst and gaseous products is directly discharged into a reactor vessel. The interior of the reactor vessel is arranged such that the outlet of the reactor riser is located close to and directed at the top of the reactor vessel. The reactor vessel operates with a dense bed of catalyst having an upper bed level that is only a short distance below the outlet of the reactor riser. The cyclone separators are located to the outside of the reactor riser and circulate catalyst back to the dense bed of the reactor section. The quenching takes place downstream of the cyclone separators.

摘要： Hydrocarbon feedstock is dispersed in an FCC riser by directing jets of atomized feed droplets into a flowing stream of catalyst particles in a direction substantially perpendicular to the axis of the riser. By directing the feed into the riser in a substantially perpendicular direction feed is more quickly dispersed across the entire cross section of the riser. By quickly dispersing feed the mixture of hydrocarbons and catalyst particles is completely mixed after traveling only a short distance along the riser from the point of feed introduction. Reducing this contact zone length improves the quality of riser products by eliminating variations in the contact time between the feed and catalyst. In addition to the short contact zone length this invention also combines the desirable features of catalyst pre-acceleration and feed atomization. The apparatus used for practicing this invention may also include a central strike surface in the riser to prevent erosion of the riser wall from the radially directed feed jets.

摘要： A process for the fluidized catalytic cracking of an FCC feedstock uses a backmix catalyst cooler to heat FCC feed and control tube wall temperatures to avoid coking and thermal cracking. Heated FCC feed contacts the catalyst in a reactor riser to convert the feedstock. Prior heating of the feed raises its temperature so that it is more easily vaporized and better distributed throughout the riser. Using FCC catalyst to heat the feed maintains the heat balance between the reactor and the regenerator so that the catalyst circulation to the riser can remain unchanged. The backmix type cooler has heat exchange tubes located in a separate vessel. Catalyst from the dense bed of a regeneration zone is circulated to a section of the cooler located above the heat exchange tubes. One form of the invention uses two conduits to transfer catalyst to the section of the cooler above the exchange tubes and thereby control the temperature of the catalyst above the heat exchange tubes. Heat exchange and tube wall temperatures are controlled by the addition of fluidizing gas.
