Abstract:
To provide a monitoring device that estimates the flow rate of flare gas released from a flare stack.SOLUTION: A monitoring device includes an image acquisition unit that acquires an image of flare, an image analysis unit that classifies pixels included in the image into a first pixel close to the flare pixel and a second pixel close to the background image on the basis of a brightness value of a predetermined flare pixel in which flare is captured and a brightness value of a predetermined background pixel in which non-flare is captured, and calculates the total number of pixels classified into the first pixel, a flare gas flow rate estimation unit that estimates the flow rate of flare gas on the basis of the total number of pixels, and an output unit that issues an alarm by comparing the flow rate of the flare gas with a predetermined threshold value.SELECTED DRAWING: Figure 1
