Abstract

1415067 Controlling alkylation units TEXACO DEVELOPMENT CORP 11 July 1973 [16 Aug 1972] 32952/73 Heading B1X [Also in Division C5] A method for controlling an alkylation unit to control the hydrocarbon content of recycle acid, said alkylation unit including a contactor wherein an olefin-isoparaffin mixture is contacted with acid and the contactor provides an acid-hydrocarbon mixture to an acid settler which seperates a hydrocarbon phase and an acid phase to provide hydrocarbon enriched acid and crude alkylate, a portion of the hydrocarbon enriched acid being discharged while the remainder of the hydrocarbon enriched acid is recycled back to the contactor as the recycle acid along with fresh acid entering the alkylation unit, which method comprises the steps of sensing a condition of each of the fresh acid, the crude alkylate and the recycle acid, sensing an interface level between the acid phase and the hydrocarbon phase in the acid settler, providing a signal corresponding to a predetermined hydrocarbon content for the recycle acid, controlling the interface level in the acid settler in accordance with a control signal, providing the control signal in accordance with the condition signals, the sensed level signal and the target hydrocarbon contents signal to control the hydrocarbon content of the recycle acid. The signals may indicate the density of the various liquids and may be fed to a computer which produces the control signal.
