Abstract: A multi-component gas analysis system includes a spectrometric analysis device configured to obtain ratio of each of first components in a multi-component gas based on an absorption spectrum of light that has transmitted through the multi-component gas; a density measurement device configured to measure a first density of the multi-component gas; and a calculation device configured to calculate a ratio of each of second components in the multi-component gas using the ratio of each of the first components obtained by the spectrometric analysis device and the first density measured by the density measurement device, the second components being components that cannot be obtained by the spectrometric analysis device.

Abstract: To estimate a state of a natural resource in pipeline equipment during extraction in an oil field, provided is an apparatus including a data acquiring section that acquires measurement data, measured by a measurement device, indicating a state of a natural resource that is a fluid flowing through an extraction network for extracting the natural resource; a state estimating section that estimates the state of the natural resource at least at one location differing from a location where the measurement device is provided in a flow path of the extraction network, using the measurement data and a model of the extraction network; and a margin calculating section that calculates a margin until flow path blocking matter is generated in the extraction network, based on the estimated state of the natural resource.

Abstract: An evaluation apparatus includes a storage unit that stores a model modeling a state of a facility provided in a plant, a simulator that adjusts a parameter that is set in the model so that a difference between an actual measurement value based on a process value of the facility in a first state and a first simulate value calculated by using the model is equal to or less than a threshold, and an estimation unit that estimates a first estimated operating point that indicates an operation state of the facility in the first state based on the adjusted parameter.

Abstract: A plant performance evaluation apparatus includes a first storage storing a first static model indicating a model of a first steady state in a plant, a second storage storing a first dynamic model indicating a model of a dynamic state of the plant, a model converter configured to convert the first dynamic model to a second static model indicating a model of a second steady state of the plant, and to store the second static model into the first storage, the first steady state indicating a steady state of the plant temporally before the second steady state, a comparator configured to compare parameters included in the first static model with parameters included in the second static model and to output a comparison result, and a display configured to display the comparison result output from the comparator.
