In some aspects, the integrated processes can allow for conversion of olefins generated during a fluidized coking process to form additional liquid products. Additionally or alternately, in some aspects the integrated processes can allow for separation of syngas from the flue gas/fuel gas generated by a gasifier integrated with a fluidized coking process.

Because the vapors available are shared among and between compressor stages, the number of compressors can be reduced, improving economics. Balancing vapor mass flow through incremental compressor stages which traverse multiple process stages by splitting vapors between compressor stages enables the overall vapor-compression system to be tailored to individual process energy requirements and to accommodate dynamic fluctuations in process conditions. 1. A multiple-stage , energy-integrated system comprising:(a) a plurality of process sub-systems collectively configured for continuously or semi-continuously converting a feedstock into one or more products, wherein said plurality of process sub-systems is configured to utilize vapor-liquid phase changes; and(b) a vapor-compression sub-system, wherein said vapor-compression sub-system includes at least a first vapor compressor and a second vapor compressor, wherein said first vapor compressor is a mechanical vapor compressor or a thermal vapor compressor, and wherein said second vapor compressor is a mechanical vapor compressor or a thermal vapor compressor,wherein said first and second vapor compressors are sequentially arranged and configured to increase pressure and condensing temperature of first vapors within a first process sub-system and second vapors within a second process sub-system that is physically separated from, but in flow communication with, said first process sub-system;wherein said first vapor compressor is in flow communication with said second process sub-system, or a third process sub-system, via a first compressed-vapor line, ...

A fluid coking unit for converting a heavy oil feed to lower boiling products by thermal has a centrally-apertured annular baffle at the top of the stripping zone below the coking zone to inhibit recirculation of solid particles from the stripping zone to the coking zone. By inhibiting recirculation of the particles from the stripping zone to the coking zone, the temperatures of the two zones are effectively decoupled, enabling the coking zone to be run at a lower temperature than the stripping zone to increase the yield of liquid products.
