Cracking property determination and process control |
| abstract |
A method of determining or predicting a value Px of a property of a feed X to a steam cracking process or yield of said process, which method comprises measuring the absorption Dix of said material at more than one wavelength in the region 600-2600 nm, comparing signals indicative of said adsorptions or a mathematical function thereof with signals indicative of absorptions Dim or mathematical function 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 Sm with property Pm said standard having the smallest average value of the absolute difference at each wavelength i between the signal for the material and the signal for the standard Sm to obtain Px, with averaging of said properties or yields Pm when more than one standard Sm is chosen. If desired the method can be used as such to control the steam cracking process by comparison of Pm with the desired value and adjustment of the process to minimize deviations from Pm; in an alternative process the signal (or function thereof) of the standard(s) with the smallest average value of the absolute difference may be used directly to control the process. |
