摘要： A method for determining contamination in marine diesel lubricating oils. The method has been found to have particular utility in estimating asphaltenes contamination in marine diesel lubricating oils. The method includes the steps of: (a) obtaining spectral raw data over a frequency range substantially equivalent to that of ultraviolet-visible light for reference lubricating oil samples with known properties and concentrations of asphaltenes; (b) performing chemometric techniques to the spectral raw data obtained in step (a) to develop a calibration model and calibrate the spectral data with actual values for parameters reflecting the level of asphaltenes contamination of the reference samples, the actual values determined by means of conventional analytical methods; (c) obtaining spectra of samples of marine diesel lubricating oil of unknown concentration of asphaltenes over a frequency range substantially equivalent to that of ultraviolet-visible light; and (d) processing the obtained spectral raw data of step (c) and applying the developed calibration model to the processed data in order to determine the parameters reflecting the level of asphaltenes present in the marine diesel lubricating oil.

摘要： A method and system for controlling an HF alkylation system comprising a reactor, a settler, an HF acid regenerator and a source of fresh HF acid wherein a stream of olefins and a stream of isobutanes are contacted in the reactor in the presence an HF acid catalyst. At least the reactor feed is sampled, and the sample is passed to an analyzer using an attenuated total reflectance cell. Signals are generated which are representative of infrared spectra of the samples in a range providing information on the amount of at least one of HF, water, ASO and sulfolane. These signals are simultaneously determined and generated because all absorb in the same spectral region. This aspect provides for viewing these distortions of the main HF absorption band to quantify these three components. The infrared spectra signals are compared with stored signals to generate control signals; and at least one of HF, water and sulfolane fed to the reactor feed is adjusted in response to the control signal.
