An email for TAYO

Tako: I hear that you are the new Alkylation contact for Puget Sound. I am in our Planning group and am checking on the economics' of the alky unit. Our model expert tells me that the model currently has the following relationship for propylene alkylation. Does this relationship seem to make sense to you? I know we looks some hydrocarbon into the acid but am not sure how much. In my memory this seems like it is using to much Isobutane but need not thoughts. Thanks for your input.
