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.

Abstract: Low pour fuel oils are obtained by first converting waxy pour residua into the corresponding viscous pour residua by deep vacuum fractionation, with or without auxiliary visbreaking or thermal or catalytic cracking, and then blending with sufficient low pour cutter stock to produce fuel oils having commercially acceptable viscosities and pour points.
