UOP LLC, formerly known as Universal Oil Products, is a multi-national company developing and delivering technology to the petroleum refining, gas processing, petrochemical production, and major manufacturing industries. The company's roots date back to 1914, when the revolutionary Dubbs thermal cracking process created the technological foundation for today's modern refining industry. In the ensuing decades, UOP engineers generated thousands of patents, leading to important advances in process technology, profitability consultation, and equipment design. Wikipedia.

A process for the production of butadiene is presented. The process combines the separation of butenes and butadienes extracted from a non-oxidated dehydrogenation process with the separation of butenes and butadienes from an oxidative dehydrogenation process to increase the butadiene yields and reduce the equipment for the recovery of a butadiene product.

Methods and systems for recovering a hydrocarbon from fluid catalytic cracking (FCC) slurry and for separating a FCC slurry stream from a FCC effluent are provided. An exemplary hydrocarbon recovery method comprises the steps of: contacting a feed 5 with a catalyst in a FCC reactor under conditions suitable to crack one or more hydrocarbons and generate a FCC effluent; separating the FCC effluent with a fractionation column to generate a product stream and a FCC slurry that collects in a lower portion of the fractionation column; drawing a first FCC slurry stream at a first temperature from a first location in the fractionation column; drawing a second FCC slurry 10 stream at a second temperature from a second location in the fractionation column, and separating a hydrocarbon from the second FCC slurry stream, wherein the second temperature is higher than the first temperature.

An asymmetric integrally-skinned flat sheet membrane comprising a miscible blend of an aromatic polyethersulfone (PES) polymer and an aromatic polyimide polymer is used for gas separations such as hydrogen purification, separation of hydrogen and methane and to separate other gases and liquids. UV radiation may be applied to the surface of the membrane for improved properties.

A process and apparatus are disclosed for hydrocracking a hydrocarbon feed in a hydrocracking unit and hydrotreating a vaporous hydrocracked stream. The hydrotreated effluent stream can be separated and stripped to produce a ULSD stream fit for storage without further processing. The hydrocracked liquid stream can be stripped and fractionated to produce a diesel stream that can be transported to the hydrotreating unit.

Apparatus and methods are provided for converting methane in a feed stream to acetylene. A hydrocarbon stream is introduced into a supersonic reactor and pyrolyzed to convert at least a portion of the methane to acetylene. The reactor effluent stream may be treated to convert acetylene to another hydrocarbon process.

Methods for reducing flue gas particulate emissions from fluid catalytic cracking unit regenerators are provided. In one embodiment, a method for reducing flue gas particulate emissions from an FCC unit regenerator includes the steps of combining biochar with a hydrocarbon feedstock to generate a biochar-containing feedstock and contacting the biochar-containing feedstock with an FCC catalyst. In another embodiment, a method for reducing flue gas particulate emissions from a FCC unit regenerator includes the steps of fluidizing catalyst fines and biochar particles in a fluidizing gas and adhering a portion of the catalyst fines to the biochar particles while in the fluidizing gas.

An apparatus and process is disclosed for mitigating coking in an FCC reactor plenum. The apparatus and process utilize a baffle to create a inner volume for the product vapors to prevent contact with a relatively cool plenum. The baffle also limits the amount of the time the product vapors spend in the plenum minimizing time for coke formation and limit product vapors from entering low fluidization zones.
