摘要： Processes for upgrading a hydrocarbon for a predetermined period of time. The process can include determining an amount of one or more contaminant-containing compositions that will be present in a pyrolysis effluent based, at least in part, on a composition of a hydrocarbon feed to be steam cracked, a temperature the hydrocarbon feed will be heated at during steam cracking, a residence time the hydrocarbon feed will be heated at the temperature during steam cracking, or a combination thereof. In some examples, the process can also include taking one or more steps to allow the hydrocarbon feed to be steam cracked for at least as long as a predetermined period of time, controlling process conditions within one or more separation stages to favor certain product compositions, introducing a predetermined amount of one or more agents into various locations of the process, or any combination thereof.

摘要： Processes and systems for pyrolysing a hydrocarbon feed for a predetermined period of time, e.g., by steam cracking. The process can include determining a first amount of silicon material present in the hydrocarbon feed that is to be steam cracked to produce a steam cracker effluent. The process can also include determining a second amount of silicon material that will be present in a steam cracker naphtha that is to be separated from the steam cracker effluent.

摘要： The invention generally relates to processes for reducing and removing foulant and foulant precursors from regenerated amine mixtures and to equipment useful in such processes. Such amine mixtures are useful for removing one or more acidic gases such as CO 2 or H 2 S from olefin hydrocarbon streams. A first feed comprising regenerated amine, foulant, and foulant precursors is provided. A second feed comprising aromatic hydrocarbons is provided. The first and second feeds are combined and then separated to form first and second products. The first product is an upgraded regenerated amine mixture that comprises the first feed's amine. The second product comprises second feed's aromatic hydrocarbons and a portion of the first feed's foulant.
