Process for removing nitrile in etherification process |
| abstract |
This invention provides an improved etherification process (20, 30) that reduces the amount of acidic ion-exchange resin catalyst that is deactivated by nitriles. This process uses a water phase to remove nitriles from a hydrocarbon phase followed by an alcohol phase to remove the nitriles from the water phase. A hydrogenation catalyst is used to convert the nitriles to amines so that they can be more easily removed from the alcohol phase. This invention also provides a process to remove nitriles (10, 60). This invention further provides an improved etherification process that reduces the amount of acidic ion-exchange resin catalyst that is deactivated by nitriles. These processes use a water phase to remove nitriles from a hydrocarbon phase followed by a stream, or fuel gas, phase to remove the nitriles from the water phase. |
