Processes for pyrolyzing biomass. A catalyst is used to both pyrolyze and deoxygenate the biomass within the pyrolysis zone. A source of carbon monoxide is also passed to the pyrolysis reactor. The source of carbon monoxide may comprise a stream of gas that includes carbon monoxide, or a material capable of generating or being converted in carbon monoxide within the pyrolysis zone. The carbon monoxide may be used as a reactant for a water gas shift reaction or as a reducing agent to remove oxygen from oxygenated hydrocarbons. The catalyst preferably comprises iron (III) oxide.

The present invention relates to a hydrotreating process that includes providing a vacuum gas oil stream; heating the vacuum gas oil stream; passing the heated vacuum gas oil stream to a hydrotreating reactor; passing the hydrotreated effluent to a hot separator to form a gas stream and a liquid stream; passing the gas stream to a cold separator to form a heavy liquid stream, a light liquid stream and a vapor stream; and passing the vapor stream to an amine scrubber. Aspects of certain embodiments of the present invention also relate to a hydrotreating process in which the hydrotreating reactor is operated at a pressure within the range of approximately 35-50 kg/cm^(2)g.


Patent
Uop Llc | Date: 2016-09-30

Processes for separating a feed stream for a combined hydrotreating zone into multiple components. The hydrotreating zone receives at least two streams from the separation, preferably a naphtha stream and a diesel stream. The two streams are treated in the hydrotreating zone and then separated into naphtha and diesel streams. In at least one embodiment, three separation columns are used. In at least one embodiment, two separation columns are used.


Processes and apparatuses for co-processing pyrolysis effluent and a hydrocarbon stream in which a char produced by the catalytic cracking of the pyrolysis effluent is recovered and utilized to provide energy, such as heat to the catalytic cracking zone. The char can be burned in various combustion zones associated with the catalytic cracking zone. The char is produced from a renewable resource.

A process for treating an ionic liquid containing waste stream is described. If there is a liquid waste stream, the liquid waste stream is introduced into a liquid treatment zone. The ionic liquid in the liquid waste stream is neutralized. The concentration of the ionic liquid in the liquid waste stream is determined, and the allowed concentration of the ionic liquid in the liquid waste stream is determined. The concentration of the ionic liquid in the neutralized liquid waste stream is reduced to the allowed concentration, and the liquid waste stream having the allowed concentration is released. If there is a vapor waste stream, the vapor waste stream is introduced into a vapor treatment zone. The vapor waste stream is treated to form a treated vapor waste stream, and the treated vapor waste stream is released to a plant vapor treatment zone.


Patent

A method of controlling a hydrocarbon conversion process is described. The method involves introducing a reactant into a reaction zone containing an ionic liquid catalyst. The reaction zone has at least two zones. The mass transfer resistance in the second zone is greater than the mass transfer resistance in the first zone.


Patent

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.


The present invention involves processes and equipment for handling chloride in an ionic liquid alkylation system. The processes involve not only breaking down the organic chloride to active HCl for ionic liquid activation, but also recovering HCl in the effluent downstream to maintain the HCl requirements while also reducing HCl emissions. This equipment may be used in conjunction with an isomerization reaction zone which is integrated into the ionic liquid alkylation process to further isomerize n-paraffins to isoparaffins for recycle to the alkylation reaction zone.


A medium separator is used to recover a gaseous stream from a hydroprocessed liquid stream for hydrogen recovery in a hydrogen recovery unit. A medium flash drum may further remove liquid components from the gaseous stream prior to hydrogen recovery in the hydrogen recovery unit.


Patent
Uop Llc | Date: 2017-03-15

One exemplary embodiment can be a process for treating a hydroprocessing fraction. The process can include obtaining a bottom stream from a fractionation zone, and passing at least a portion of the bottom stream to a film generating evaporator zone for separating a first stream containing less heavy polynuclear aromatic compounds than a second stream.
