Abstract
A system and computer program product are provided for calculating one or more indicative properties, e.g., one or more of the cetane number, octane number, pour point, cloud point and aniline point of oil fractions, from the density and Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) of a sample of an oil sample.
Claims
exact text as granted — not AI-modified1 . A system for assigning an indicative property to a gas oil fraction or a gasoline fraction of an oil sample, wherein the oil sample is selected from the group consisting of crude oils, bitumens, heavy oils and shale oils, the system comprising:
a Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR MS) that outputs FT-ICR MS data; a non-volatile memory device that stores software program modules and data, the data including FT-ICR MS data indicative of intensities at corresponding double bond equivalents (DBE) derived from the oil sample; a processor coupled to the memory device; a first software program module, executed by the processor, that processes FT-ICR MS data derived by the Fourier transform ion cyclotron resonance mass spectrometer from the crude oil sample, wherein the processing includes the calculation of an FT-ICR MS index (FTMSI) as a summation of the intensity for a range of double bond equivalent (DBE); and a second software program module that derives the indicative property of the gas oil fraction or the naphtha fraction as a function of the FTMSI and a density of the oil sample.
2 . The system as in claim 1 , wherein the summation of the intensity for the range of DBE is according to the equation

where intensity=the intensity for each DBE.
3 . The system as in claim 1 , wherein the FT-ICR MS covers masses that are in the range 150-1400 m/z.
4 . The system as in claim 1 , wherein the carbon numbers detected by FT-ICR MS are in the range 1-60.
5 . The system as in claim 1 , wherein the double bond equivalents calculated by FT-ICR MS are in the range 1-40.
6 . The system as in claim 1 , wherein the oil sample is crude oil.
7 . The system as in claim 1 , wherein the indicative property is a cetane number.
8 . The system as in claim 1 , wherein the indicative property is a pour point.
9 . The system as in claim 1 , wherein the indicative property is a cloud point.
10 . The system as in claim 1 , wherein the indicative property is an aniline point.
11 . The system as in claim 1 , wherein the indicative property is an octane number.
12 . The system as in claim 1 , wherein plural indicative properties are calculated including at least two indicative properties selected from the group consisting of cetane number, pour point, cloud point, aniline point and octane number.
13 . The system as in claim 1 , wherein the indicative property is of a gas oil fraction boiling in the nominal range 180-370° C.
14 . The system as in claim 1 , wherein the indicative property is of a gasoline fraction boiling in the nominal range 36-180° C.
15 . A computer program product to determine an indicative property of a gas oil fraction or a gasoline fraction of an oil sample, wherein the oil sample is selected from the group consisting of crude oils, bitumens, heavy oils and shale oils, comprising a non-transitory computer readable medium having computer readable program code embodied therein that, when executed by a processor, causes the processor to:
accept the value of the density of the crude oil sample; accept Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR MS) data indicative of intensities at corresponding double bond equivalents (DBE) derived from the oil sample; calculating and assigning a FT-ICR MS index value as a function of the FT-ICR MS intensity for each double bond equivalent (DBE); and calculating and assigning the indicative property of the gas oil fraction or the naphtha fraction as a function of the FT-ICR MS index value and the density of the oil sample.
16 . The computer program product as in claim 6 , wherein calculating and assigning a FT-ICR MS index value as a function of the FT-ICR MS intensity for each double bond equivalent (DBE) is according to the equation
FTMSI

where intensity=the intensity for each DBE.
17 . The computer program product as in claim 6 , wherein the FT-ICR MS covers masses that are in the range 150-1400 m/z.
18 . The computer program product as in claim 6 , wherein the carbon numbers detected by FT-ICR MS are in the range 1-60.
