Abstract
A system and a method is provided for calculating and assigning one or more indicative properties (e.g., cetane number, pour point, cloud point and/or aniline point) of a fractions of a crude oil sample based upon gas chromatographic simulated distillation data.
Claims26
A system for assigning an indicative property to a fraction of an oil sample based upon simulated distillation (SD) data, the system comprising:
- a non-volatile memory device that stores calculation modules and data, the data including SD data indicative of weight percent amount distilled across a range of boiling points of the oil sample;
- a processor coupled to the memory;
- and
- a calculation module that calculates and assigns the indicative property of a fraction of the oil sample as a function of the mid-boiling point or the weighted average boiling point determined from the SD data.
A system for assigning an indicative property to a fraction of an oil sample comprising:
- a gas chromatograph that outputs simulated distillation (SD) data;
- a non-volatile memory device that stores calculation modules and data, the data including the SD data indicative of weight percent amount distilled across a range of boiling points of the oil sample;
- a processor coupled to the memory;
- and
- a calculation module that calculates and assigns the indicative property of a fraction of the oil sample as a function of the mid-boiling point or the weighted average boiling point determined from the SD data.
A method for operating a computer to assign an indicative property to a fraction of an oil sample based upon simulated distillation (SD) data, the method comprising:
- entering into the computer SD data indicative of weight percent amount distilled across a range of boiling points of the oil sample;
- calculating and assigning the indicative property of a fraction of the oil sample as a function of the mid-boiling point or the weighted average boiling point determined from the SD data.
A method for assigning an indicative property to a fraction of an oil sample comprising:
- operating a gas chromatograph to output simulated distillation (SD) data;
- entering into a computer the outputted SD data indicative of weight percent amount distilled across a range of boiling points of the oil sample;
- calculating and assigning the indicative property of a fraction of the oil sample as a function of the mid-boiling point or the weighted average boiling point determined from the SD data.
