摘要： A naphtha hydrotreating process involves the use of a sulfur guard bed (SGB) with a controlled bypass which allows for control of the sulfur in the feed to a downstream processing unit. The SGB is installed on the light ends stripper bottoms stream in a naphtha hydrotreating unit.

摘要： Systems, apparatuses, and methods are described for determining the location of a worker in a plant, such as a petrochemical manufacturing or refining facility in order to render an augmented view of at least one asset in the vicinity of a fiducial marker. A field worker mobile device may scan the fiducial marker and render operating values for a measurable element of the assets in the field of view of the mobile device. Location of the mobile device with respect to the assets in the vicinity of the fiducial marker may be determined based upon the known location and orientation of the fiducial marker and/or the known location and orientations of the assets relative to the fiducial marker.

摘要： Processes and apparatuses for alkylating aromatic hydrocarbons with an alkylating reagent to produce an alkylated aromatic product are described. The processes and apparatuses use a riser reactor operated at a superficial velocity of 10 m/s to 25 m/s to produce the alkylated aromatic product. In some embodiments, a combination of steam and aromatic hydrocarbon is used to lift the catalyst.

摘要： Processes incorporating a common organic chloride decomposition reactor and chloride treater to be used by both the C4 and C5-6 isomerization reaction zones are described. A portion of the C4 isomerization reaction zone off gas is routed to the C4 HCl absorber, which provides about 85% of the HCl requirement for the C4 isomerization reaction zone. A small amount of the C5-6 isomerization reaction zone off gas is mixed with the C4 isomerization reaction zone off gas portion going to the C4 HCl absorber.

摘要： The subject process enhances catalytic activity for demetallization and desulfurization of a residue feed stream by splitting a recycle hydrogen stream and feeding each of the split hydrogen streams to the first and second stages of demetallation and desulfurization, respectively, with interstage separation. The recycle hydrogen stream may first undergo scrubbing to remove acid gases and compression before recycle. The recycle hydrogen stream is taken from a first hot vapor stream from the first hydrotreating unit and a second hot vapor stream from the second hydrotreating unit.

摘要： A process and apparatus for hydrocracking a hydrocarbon stream that feeds a cold stripped stream and a hot stripped stream to a prefractionator from which a prefractionated overhead stream and a prefractionated bottoms stream are passed to a product fractionation column. The product fractionation column may produce three products, light naphtha, heavy naphtha and distillate omitting the need for a naphtha splitter column. Data may be received from a stream in fluid communication with the foregoing process and apparatus.

摘要： A process and an apparatus are disclosed for the recovery of components from a hydrocarbon gas stream containing significant quantities of components more volatile than methane (hydrogen, nitrogen, etc.). The gas stream is partially condensed, then the remaining vapor is expanded to lower pressure and supplied to a fractionation tower at a mid-column feed position. The condensed liquid is cooled and divided into two portions. The first portion is expanded to tower pressure, heated by cooling the liquid, and supplied to the tower at a lower column feed position. The second portion is expanded to tower pressure and supplied to the tower at an upper mid-column feed position. A distillation vapor stream is withdrawn from the fractionation tower below the mid-column feed position and is heated, compressed to higher pressure, and cooled to substantial condensation before it is expanded and supplied to the tower as its top feed.

The gas stream is partially condensed, then the remaining vapor is expanded to lower pressure and supplied to a fractionation tower at a mid-column feed position. The condensed liquid is cooled and divided into two portions. The first portion is expanded to tower pressure, heated by cooling the liquid, and supplied to the tower at a lower column feed position. The second portion is further cooled, expanded to tower pressure, and supplied to the tower at a top feed position. The tower overhead vapor is heated by cooling the second portion. The quantities and temperatures of the feeds to the tower maintain the overhead temperature of the tower whereby the major portion of the desired components is recovered.
