Abstract
A method for operating a dimerization reactor that receives a hydrocarbon feed and produces an output stream comprising a light hydrocarbon component, a dimer and an alcohol component comprises: (a) separating the first output stream into a top stream containing the light hydrocarbon and a bottom stream containing the dimer, with the alcohol being present in the top stream or the bottom stream or both; (b) contacting at least one of the bottom and top streams with a water stream so as to extract at least a major portion of the alcohol therefrom, thereby forming an water/alcohol stream; (c) contacting the water/alcohol stream with a hydrocarbon stream so as to extract at least a major portion of the alcohol present in the water/alcohol stream into the hydrocarbon stream, thereby forming an alcohol-enriched hydrocarbon stream; and (d) feeding the alcohol-enriched hydrocarbon stream into the dimerization reactor.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
