    摘要： An analytical system for sampling a feed in a process line e.g. crude oil has first and second lines from the process line to first and second separation means, lines from said separation means to an analytical means e.g. an NIR spectrophotometer and computer, and means for cleaning the separation means. In the method, the flow of oil sample flows in one direction from process line to first separation means and analytical means at the same time as a backwash liquid passes form the back of the second separation means towards the process line to clean it.

    摘要： A method of determining or predicting a value P x of a property (e.g. octane number) of a material X or a property of a product of a process from said material or yield of said process, which method comprises measuring the absorption D ix of said material at more than one wavelength in the region 600-2600 nm, comparing the said absorptions or a derivative thereof with absorptions D im or derivatives thereof at the same wavelength for a number of standards S in a bank for which the said property or yield P is known, and choosing from the bank at least one standard S m with property P m said standard having the smallest average value of the absolute difference at each wavelength i between the absorption D i x (or derivative thereof) for the material and the absorption D i m (or derivative thereof) for the standard S m to obtain P x , with averaging of said properties or yields P m when more than one standard S m is chosen.
