Publication number: 20240425768Abstract: 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.Type: ApplicationFiled: October 3, 2022Publication date: December 26, 2024Inventors: Mark A.

Publication number: 20240034703Abstract: Processes are provided for removing contaminants from a refinery gas. Such process can include recovering a process gas comprising ethylene and propylene from a steam cracker effluent recovered from a stream cracker in a steam cracker facility. A refinery gas can be recovered from a refinery facility. The process gas can be compressed in a plurality of compressor stages. A pressure of the refinery gas can be determined. A compressor stage in the plurality of compressor stages can be selected for introducing the refinery gas using the determined pressure of the refinery gas. The refinery gas can be introduced into the selected compressor stage to produce a combined gas that can include the process gas and the refinery gas.
