A METHOD FOR REMOVING CHLORIDES FROM HYDROCARBON STREAM BY STEAM STRIPPING

A method for removing chloride impurities from a heavy hydrocarbon stream is disclosed. The heavy hydrocarbon stream is contacted with a stripping medium at a temperature ranging between 100 - 450 °C and at a pressure ranging between 0.1 - 2 bar with ratio of the heavy hydrocarbon stream to the stri...

Zusammenfassung:	A method for removing chloride impurities from a heavy hydrocarbon stream is disclosed. The heavy hydrocarbon stream is contacted with a stripping medium at a temperature ranging between 100 - 450 °C and at a pressure ranging between 0.1 - 2 bar with ratio of the heavy hydrocarbon stream to the stripping medium ranging between 1 - 30; wherein the temperature is maintained below the initial boiling point of the hydrocarbon stream. L'invention concerne un procédé d'élimination d'impuretés de chlorure à partir d'un courant d'hydrocarbures lourds. Le courant d'hydrocarbures lourds est mis en contact avec un milieu de séparation à une température se situant dans la plage d'entre 100 - 450 °C et à une pression se situant dans la plage d'entre 0,1 - 2 bar avec le rapport du courant d'hydrocarbures lourds au milieu de séparation se situant dans la plage d'entre 1 - 30 ; la température étant maintenue au-dessous du point d'ébullition initial du courant d'hydrocarbures.
