摘要： Methods and systems for managing a decomposition process are disclosed. An example method can comprise estimating a coking rate for a process based on a coking model. The coking model can comprise a pyrolytic coking term and a catalytic coking term. An example method can comprise, performing at least a portion of the process, receiving a parameter for the process, and adjusting an operation of the process based on the parameter.

摘要： Systems and methods for producing olefins and/or aromatics are disclosed. Methods disclosed includes thermal hydro-processing of crude oils and/or heavy oils and/or residues, in a thermal hydro-processing unit, to produce intermediate products, which can then be used to make valuable chemicals such as olefins and aromatics.

摘要： Methods and systems for producing light olefins are disclosed. A feedstock comprising crude oil is distilled to produce a plurality of streams including a naphtha stream and a vacuum residue stream. The naphtha is fed to a steam cracking unit to produce light olefins, C4 hydrocarbons, pyrolysis gasoline and pyrolysis oil. The vacuum residue stream is hydrocracked to produce additional naphtha and heavy unconverted oil. The heavy unconverted oil and the pyrolysis oil from steam cracking unit can be deasphalted to produce deasphalted oil and pitch product. The deasphalted oil can be further hydrocracked to produce naphtha. The pitch product can be gasified to produce synthesis gas, which is further used to produce methanol. The methanol can be used to react with isobutylene of the C4 hydrocarbon stream from steam cracker to produce methyl tert-butyl ether (MTBE).

摘要： Methods that reduce fouling of equipment in a quench water recycling loop of a steam cracker quench system by separating tar from water in the quench water recycling loop. The methods may include settling a bottom stream comprising pyrolysis gasoline, from a quench tower, in at least two quench water settlers in parallel, each of the quench water settlers producing a settler hydrocarbon stream and a settler bottom quench water stream. The methods may also include mixing a bottom stream comprising pyrolysis gasoline, from a quench tower, with quench tower effluent water to form a combined stream. The method may further include settling the combined stream in at least two quench water settlers in parallel to produce settler hydrocarbon streams, settler bottom quench water streams, and settler process water streams.
