A method and apparatus for removing sulfur from a hydrocarbon-containing fluid stream wherein desulfurization is enhanced by improving the contacting of the hydrocarbon-containing fluid stream and sulfur-sorbing solid particulates in a fluidized bed reactor.

Desulfurization system with enhanced fluid/solids contacting

A system for enhancing fluid/solids contacting in a fluidization reactor by controlling the particle size distribution of the solid particulates in the reactor.

Enhanced fluid/solids contacting in a fluidization reactor

A novel apparatus and process, including a perforated-pipe sparger, for atomizing a liquid stream is disclosed. This novel apparatus and process can be utilized in a fluidized catalytic cracking process or in a coking process for atomizing an oil stream prior to contact with a fluidized catalyst.

Atomizer system containing a perforated pipe sparger

A novel apparatus and process, including a baffle, for contacting a first fluid with a second fluid of lower density than the first fluid in counter-current flow in a manner that increases the contacting efficiency.

Baffles for a fluid to fluid contactor

An improved apparatus and method for the fluidized catalytic cracking (FCC) of hydrocarbons. Turbulence generation means disposed on the internal surface of an FCC riser-reactor are utilized to provide for a more uniform catalyst flow pattern within the riser-reactor and to thereby provide for a better conversion and product slate.

Process and apparatus for fluidized catalytic cracking of a hydrocarbon

This invention concerns an apparatus and process for effectively contacting oil, catalyst, and a gas. This invention has specific applications in the design and operation of catalytic cracking units and specifically, the processing and upgrading of heavy oils to higher valued components.

Feed zone performance for a cat cracker

Catalytic regenerators, nozzle designs and processes suitable for introducing regeneration air into a catalytic cracking unit which substantially reduce erosion induced nozzle failures include a plurality of nozzle elements having a roughness defined upon the outside surface of said nozzle elements so as to reduce erosion due to the impact of fluidized catalyst particles within the catalytic regenerator.
