摘要： A system for processing a hydrocarbon feed has a final stage reactor and internal separator with cyclone that forms a substantially gas stream and a substantially non-gas stream. The substantially gas stream is sent directly from the final stage reactor and separator to further downstream processing.

摘要： A system for reactivating a catalyst having a predetermined heat content includes a reactor, a regenerator, and an electrically energized heater. The reactor is configured to generate a spent catalyst. The regenerator is configured to receive the spent catalyst from the reactor. The electrically energized heater has a plurality of energy emitting members at least partially immersed in the spent catalyst. The heater is configured to provide a supplemental heat content to obtain the predetermined heat content.

摘要： A dividing wall column is used in an alkylation process flow scheme to fractionate an alkylate reactor effluent to produce an iso-butane-rich stream as a recycle feed for the alkylation reactor while also separating iso-butane, normal butane and alkylate as separate product streams depending on the reactor effluent composition. In an optional embodiment, the scheme may contain propane.

摘要： A method for testing a body having a feature and an outer surface includes configuring a probe to emit a focused ultrasonic beam; configuring a control unit to control the probe, adjusting a focal distance of a focal point of the beam with reference to a test location; adjusting a position of the focal point along at least one axis with reference to the feature; emitting the beam into the outer surface; and determining a presence of a crack at the test location by evaluating % a signal response from the probe. A related apparatus includes the control unit, the transducer, and a shoe assembly having a shoe member and a shoe adapter. A coupling fluid in a variable volume chamber in the shoe adapter separates the transducer from the shoe member and allows changes in a focal distance of the focal point. The apparatus also includes one or more positioners for adjusting a position of the focal point.

摘要： Co-production a product anode grade coke and a product fuel grade coke is done using a system configured to implement a method that includes: directing an anode grade coker charge material from a tower to a first coke drum set; generating the product anode grade coke using the first coke drum set while directing a first vapor stream from the first coker drum set to the tower; directing a fuel grade coker charge material from a fractionator to a second coke drum set; generating the product fuel grade coke using the second coke drum set while directing a second vapor stream from the second coke drum set to the fractionator; and directing a third vapor stream from the tower to the fractionator while generating the product anode grade coke using the first coke drum set and generating the product fuel grade coke using the second coke drum set.

摘要： A process for slurry-phase hydrocracking of a heavy hydrocarbon feedstock in a reactor, such as an upflow bubble column reactor, includes separately introducing additive in two size ranges into the feedstock. A fine size particle additive is introduced upstream of a coarse size particle additive.
