The invention provides an improved system for separation technology intended to reduce unwanted catalyst/thermal reactions by minimizing contact of the hydrocarbons and the catalyst within the reactor.

FCC yield selectivity improvements in high containment riser termination systems

An injection of a small amount of sweet vacuum residue into an FCC feed consisting of sweet gas oil combined with shape selective catalyst additives technology improves propylene and butylene yields significantly.

FCC feed additive for propylene/butylene maximization

Fluid medium such as light cycle oil, water, FCC slurry and decanted oil, improve this method for vacuum distillation of a petroleum product. The method may be used in the petroleum refining industry for fractionating of petroleum base stock in a vacuum column. The fluid medium prevents the formation of thermoset polymers and the resultant fouling of the wash beds in the vacuum column.

Method to migrate fouling of a vacuum wash bed

This procedure uses a low carbon fuel with a FCC Catalyst Heater-Fuel Gas/Catalyst Combustion Chamber. The low carbon content fuel source will minimize CO2 emissions while satisfying unit heat balance. This will further reduce coke yield and CO2 emissions while improving energy efficiency.

Using low carbon fuel with a catalyst charge heater

This device is an FCC Catalyst Charge Heater. The device uses a catalyst cooler to preheat FCC feedstocks. It can be used with or without an FCC Catalyst Heater in the regenerator to satisfy the FCC unit heat balance while maximizing liquid volume yield and reducing FCC emissions.
