摘要： In an atmospheric fractionator, the number of theoretical stages are increased in the upper light distillate flash zone and in the middle heavy distillate flash zone. The middle distillate pumparound circuit has been eliminated. The reflux to distillate ratio for the light distillate as well as the effluent feed temperature have been substantially increased. As a result, increased yields for middle distillate (e.g. kerosene) and heavy distillate (eg diesel) have been achieved which more than offset the increased energy consumption used for the higher feed temperature In the example of hydrocracking technology, the improved fractionation has benefits in the hydrocracking unit outside of the fractionation unit Increased fractionation efficiency reduces the severity in the hydrocracking unit reactor catalyst and less hydrogen is consumed. The invention can be applied to several other refining technologies besides hydrocracking.

摘要： Disclosed is an apparatus for recovery power from an FCC product. Gaseous hydrocarbon product from an FCC reactor is heat exchanged with a heat exchange media which is delivered to an expander to generate power. Cycle oil from product fractionation may be added to the gaseous FCC product to wash away coke precursors.

摘要： A process and apparatus for indirectly exchanging heat with narrow channel in a heat exchange type reaction zone uses manifold space to interconnect the common ends of channels and to provide controlled distribution of additional reactants. The invention simplifies the operation and construction of the heat exchanging type reaction zone by directly communicating reaction channels and/or heating channels with a manifold located at the end of the channels. The manifold can provides the extra function of mixing additional reactants. The invention promotes simplified intermediate injection of reactants over tube and shell heat transfer arrangements that have been used for similar purposes. Improved process control has particular benefits for exothermic reactions. The narrow channels are preferably defined by corrugated plates. The reaction channels will contain a catalyst for the promotion of the primary reaction.
