Abstract

Systems, methods, and computer program products for fugitive emission determinations are provided. An example imaging system includes a first infrared (IR) imaging device configured to generate first IR image data of a field of view of the first IR imaging device that include one or more data entries associated with a fugitive emission from an emission source. The system further includes a computing device operably connected with the first IR imaging device and configured to receive the first IR image data from the first IR imaging device, generate spectral absorption data based on the first IR image data, and determine a gas amount associated with the fugitive emission based upon the spectral absorption data. The computing device also determines a leak rate and leak duration of the fugitive emission based upon the determined gas amount and determines a total emission loss based on the same.

First claim

1 - 20 . (canceled)

21 . An imaging system comprising:
a first infrared (IR) imaging device configured to generate first IR image data of a field of view of the first IR imaging device, wherein the first IR image data includes one or more data entries associated with a fugitive emission from an emission source; and a second infrared (IR) imaging device configured to generate second IR image data of a field of view of the second IR imaging device, wherein the second IR image data includes one or more data entries associated with a fugitive emission from an emission source; and a computing device operably connected with the first and second IR imaging device, wherein the computing device is configured to:
receive the first IR image data and second IR image data from the first IR imaging device and second IR imaging device;
generate spectral absorption data based upon the first IR image data in conjunction with the second IR image data;
determine a gas amount associated with the fugitive emission based upon the spectral absorption data;
determine a leak rate and a leak duration of the fugitive emission based upon the determined gas amount;
determine a total emission loss of the fugitive emission from the emission source based upon the determined leak rate and leak duration; and
receive a user input indicative of one or more of an open state and a closed state of the emission source.

22 . The imaging system according to claim 21 , wherein the computing device is further configured to generate an alert signal comprising the total emission loss.

23 . A computer-implemented method comprising:
receiving first IR image data from a first infrared (IR) imaging device of a field of view of the first IR imaging device, wherein the first IR image data includes one or more data entries associated with a fugitive emission from an emission source; receiving second IR image data from a second infrared (IR) imaging device of a field of view of the second IR imaging device, wherein the second IR image data includes one or more data entries associated with a fugitive emission from an emission source; generating spectral absorption data based upon the first IR image data in conjunction with the second IR image data; determining a gas amount associated with the fugitive emission based upon the spectral absorption data; determining a leak rate and a leak duration of the fugitive emission based upon the determined gas amount; determining a total emission loss of the fugitive emission from the emission source based upon the determined leak rate and leak duration; and receiving a user input indicative of one or more of an open state and a closed state of the emission source.

24 . The computer-implemented method according to claim 23 , further comprising generating an alert signal comprising the total emission loss.

25 . A computer program product comprising at least one non-transitory computer-readable storage medium having computer program code thereon that, in execution with at least one processor, configures the computer program product for:
receiving first IR image data from a first infrared (IR) imaging device of a field of view of the first IR imaging device, wherein the first IR image data includes one or more data entries associated with a fugitive emission from an emission source; receiving second IR image data from a second infrared (IR) imaging device of a field of view of the second IR imaging device, wherein the second IR image data includes one or more data entries associated with a fugitive emission from an emission source; generating spectral absorption data based upon the first IR image data in conjunction with the second IR image data; determining a gas amount associated with the fugitive emission based upon the spectral absorption data; determining a leak rate and a leak duration of the fugitive emission based upon the determined gas amount; determining a total emission loss of the fugitive emission from the emission source based upon the determined leak rate and leak duration; and receiving a user input indicative of one or more of an open state and a closed state of the emission source.

26 . The computer program product according to claim 25 , further configured for generating an alert signal comprising the total emission loss.
