A method for treating a hydrocarbon solvent, the method comprising:
- continuously introducing a hydrocarbon solvent to an liquid medium containing hydrogen ions;
- allowing the hydrocarbon solvent to be in contact with the liquid medium for at least 1 minute;
- continuously removing hydrocarbon solvent from the liquid medium to provide a treated hydrocarbon solvent stream.
A method for treating a hydrocarbon solvent, the method comprising:
- continuously introducing a hydrocarbon solvent to a resinous medium containing one or more proton donor groups;
- allowing the hydrocarbon solvent to be in contact with the resinous medium for at least 1 minute;
- continuously removing hydrocarbon solvent from the resinous medium to provide a treated hydrocarbon solvent stream.
The method of claim 14, further comprising the step of employing at least a portion of the treated hydrocarbon stream as a solvent within a polymerization process.
