Abstract
A method and/or system for rapidly determining the average composition and characteristics of a hydrocarbon mixture comprising thermally cracking the mixture to form a gaseous product, measuring the ratios or proportions of the individual components in the gaseous product, and comparing the ratios of the components present in the gaseous products with a known property of the hydrocarbon feed mixture and obtaining the average composition and intrinsic properties of the hydrocarbon feed.
Claims8
A method for determining, in a timely manner consistent with real time control of a chemical or petrochemical process, the characteristics of a crude derived feed hydrocarbon mixture, which comprises
- (a) thermally cracking a crude derived feed hydrocarbon mixture by heating to an elevated temperature for a period of time sufficient to form a gaseous fraction containing components comprising acetylene, methane, ethane, propane, ethylene, and propylene,
- (b) selecting a component from the gaseous fraction from step (a) and measuring the compositional ratios of five other components of the gaseous fraction each to the selected component to obtain five measured ratios, and
- (c) determining one or more of the feed hydrocarbon mixture characteristics selected from the group consisting of normal paraffin content, isoparaffin content, naphthene content, olefin content, aromatic content, hydrogen content, average molecular weight, and viscosity based upon the five ratios obtained in step (b).

- (b) selecting a component from the gaseous fraction from step (a) and measuring the compositional ratios of four of the five other components each to the selected component, and measuring the average boiling point of the feed hydrocarbon mixture, and
- (c) determining one or more of the feed hydrocarbon mixture characteristics selected from the group consisting of normal paraffin content, isoparaffin content, naphthene content, olefin content, aromatic content, hydrogen content, average molecular weight, and viscosity based upon the four ratios and the average boiling point obtained in step (b).
