Abstract
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.
Claims16
A filter system for the filtration of an ionic liquid which limits exposure of the ionic liquid to air and moisture, comprising:
- a first filtering zone, wherein an ionic liquid containing precipitated metal halides is filtered to provide a partially filtered product;
- and
- a second filtering zone, wherein the partially filtered product is filtered to provide a filtered product, the second filtering zone being in fluid communication with the first filtering zone,
- wherein the first filtering zone comprises at least one first filter and the second filtering zone comprises at least one second filter, and the at least one second filter has a smaller pore size than the at least one first filter.
