    Abstract: A system controls the strength of acid used as the catalyst in an alkylation unit, which reacts olefins with isoparaffin, in accordance with the average strength of the acid and the anticipated required strength of the acid. A signal corresponding to the average acid strength is developed by analog computers solving equations, hereinafter disclosed, using an output from an acid analyzer corresponding to the density of the acid and a signal corresponding to the volume of caustic used in analyzing the acid. An anticipated required acid strength signal is developed by an analog computer from signals, corresponding to the flow rate and composition of the olefin, from a flow rate sensor and chromatograph means, respectively, in accordance with equations hereinafter disclosed. Another analog computer provides signals for setting the set point of a flow recorder controller in accordance with the average acid strength signal, the anticipated required acid strength signal and equations hereinafter disclosed. The flow recorder controller controls the flow rate acid being discharged from the alkylation unit so as to control the quantity of fresh acid entering the alkylation unit thereby controlling the strength of the acid.

    Abstract: The apparatus includes a chromatograph which samples material and provides a first signal, having peaks corresponding to different constituents of the material, and a pulse signal. Each pulse in the pulse signal coincides with a different peak amplitude occuring in the first signal. In accordance with the signals from the chromatograph, one circuit determines the area under the curve, the curve being the first signal, for each peak in the first signal. Another circuit determines a different baseline for each peak and the area under each baseline. A third circuit receiving signals from the first two circuits effectively subtracts each baseline area fro a peak from the area under the curve associated with the peak to determine a peak area for each peak. The peak area signals are multiplied by thermal conductivity factors to provide signals corresponding to the concentration of the components of the material. A programmer responsive to the pulse signal from the chromatograph controls sample and hold circuits receiving the first signal from the chromatograph to provide peak height voltages. The peak height voltage for each peak is divided into a corresponding percent concentration signal to provide a correction signal. The correction signals are multiplied with the peak height voltages to provide corrected signals corresponding to the concentrations of the components of the material. The corrected signals are normalized by summing the corrected signals and dividing each corrected signal by the resulting sum signal.
