Abstract: A control system and method controls the hydrocarbon of recycle acid in an alkylation unit to maintain a predetermined hydrocarbon content. The hydrocarbon content is controlled by controlling the interface level between the acid phase and the hydrocarbon phase in an acid settler in accordance with sensed densities of fresh acid entering the alkylation unit, crude alkylate provided by the acid settler in the alkylation unit and the recycle acid. A network substantially determines the actual hydrocarbon content of hydrocarbon enriched acid leaving the acid settler a portion of which is provided as the recycle acid, along with the fresh acid, to a contactor. In the contactor, an isoparaffin and an olefin are contacted with the acid to provide an acid-hydrocarbon mix to the acid settler. The settler provides the crude alkylate for further processing.

Abstract: The existing hydrocarbon content in the recycle acid in an alkylation unit is determined. Changes in earnings associated with increasing and decreasing the hydrocarbon content conditions are also determined. The interface level separating the acid phase and the hydrocarbon phase in an acid settler in the alkylation unit is controlled in accordance with the determinations to achieve and maintain a desired hydrocarbon content for the recycle acid.

Abstract: A system controls the temperature at which olefins are contacted with an isoparaffin in the presence of acid in an alkylation unit, and the flow rate of acid entering or leaving the alkylation unit. The system senses conditions of a hydrocarbon product, which results when the acid is removed from a hydrocarbon-acid mixture after the contacting process, the contact temperature, a condition relating to the contact acid and the olefin composition. The system includes a source providing signals corresponding to the economic values related to the octane rating of alkylate, which is produced from the hydrocarbon product, to the acid consumption and to the cost of controlling the contact temperature. The system uses the signals corresponding to the sensed conditions and the economic value signals to develop control signals for apparatus that control the contact temperature and the acid flow rate.

Abstract: A control system controls the acid strength of reaction acid in an alkylation unit reacting an olefin with an isoparaffin in the presence of the reaction acid to eventually produce an alkylate. The system senses the actual reaction acid strength, the discharge acid flow rate, the flow rate of discharge acid leaving the alkylation unit, the bottom products flow rate and the alkylate content of the bottoms product from a debutanizer tower and the propylene and butylene content of the olefin stream entering the alkylation unit. Using equations hereinafter disclosed, along with economic values associated with the acid and the alkylate, the control system periodically determines the optimum reaction acid strength. When the change in the reaction acid strength necessary to achieve the optimum reaction acid strength is less than a predetermined change, the necessary change is implemented. When the necessary change is greater than the predetermined change, the reaction acid strength is changed by an increment equal to the predetermined change. Where the reaction aicd strength is decreased to achieve an optimum reaction acid strength, a minimum limit is imposed on the reaction acid strength to prevent undesirable side reactions, such as olefin polymerization, from occurring.
