PROBLEM TO BE SOLVED: To provide a method for deciding quantitative composition of crude oil comprising supply material which is to be distilled. SOLUTION: Starting with a specified base line, the absorbance of supply material is, at a specified oscillation frequency of spectrum range 16667-3840cm<-1> , measured with an IR spectrometer, and composition is decided based on relationship between characteristics/yield of product and absorbance value of supply material, and depending on kind of a spectrometer using the relationship, required characteristics, and used oscillation frequency, decision is made experimentally with multivariate regression. |
