Abstract
The present invention relates to a continuous or non-continuous ionic liquid alkylation process comprising a step for solids removal, the process further comprising the steps (a) measuring the solids content in the ionic liquid alkylation process stream by on line (in situ) or off line sampling; (b) in response to the solids measurement signal, regulating the flow of the ionic liquid side stream to be sent to the solids removal device; (c) regulating the flow of the fresh ionic liquid inlet stream, for controlling the solids content in the ionic liquid alkylation process to a pre-defined level. The process of the invention provides a means to more efficiently run an ionic liquid alkylation process.
