主权项

1. An amine mixture upgrading process, comprising:
(a) providing a first mixture, the first mixture comprising amine and foulant precursors; (b) providing a second mixture, the second mixture comprising aromatic hydrocarbons; (c) combining the first and second mixtures; (d) separating third and fourth mixtures from the combined first and second mixtures, wherein (i) the third mixture comprises ≧60.0% of the first mixture's amine, and (ii) the fourth mixture comprises <40.0% of the first mixture's amine, ≧60.0% of the first mixture's foulant precursors, and ≧60.0% of the second mixture's aromatic hydrocarbons; and (e) extracting amine from the fourth mixture to produce an extract and a raffinate, wherein (i) the extract comprises ≧60.0% of the fourth mixture's amine and (ii) the raffinate comprises ≧60.0% of the fourth mixture's aromatic hydrocarbon.
