20100126948 | FILTERING PROCESS AND SYSTEM TO REMOVE AICI3 PARTICULATES FROM IONIC LIQUID - A process for the filtration of an ionic liquid involves feeding an ionic liquid containing precipitated metal halides to a first filtering zone, which includes at least one first filter, to provide a partially filtered product. The process further includes subsequently feeding the partially filtered product to a second filtering zone, which includes at least one second filter having a smaller pore size than the at least one first filter, to provide a filtered product. A filter system capable of filtering precipitated metal halides from ionic liquid is also disclosed. | 05-27-2010 |

20100130800 | Liquid-Liquid Separation Process Via Coalescers - A process for separating an ionic liquid from hydrocarbons employs a coalescer material having a stronger affinity for the ionic liquid than the hydrocarbons. The coalescer material can be a high surface area material having a large amount of contact area to which ionic liquid droplets dispersed in the hydrocarbons may adhere. The process includes feeding a mixture comprising ionic liquid droplets dispersed in hydrocarbons to a coalescer comprising the coalescer material. The process further includes a capture step involving adhering at least a portion of the ionic liquid droplets to the coalescer material to provide captured droplets and a coalescing step involving coalescing captured droplets into coalesced droplets. After the capture and coalescence steps, the coalesced droplets are allowed to fall from the coalescer material to separate the ionic liquid from the hydrocarbons and provide a hydrocarbon effluent. | 05-27-2010 |
