摘要： PROBLEM TO BE SOLVED: To provide a means which generates electricity, while generating a minimum amount of carbon dioxide, recovers the entire amount of the generated carbon dioxide, and separates and recovers high purity nitrogen and argon gas at the same time. SOLUTION: A fuel cell power generation generates electric power by separately introducing reformed fuel and air into the electrodes of a fuel cell without a premixed combustion reaction of fuel and air. With the use of this feature, the remaining oxygen is separated from the nitrogen concentrated gas of an outlet of an air electrode side to produce high purity nitrogen gas, and the concentrated carbon dioxide is separated from a fuel electrode outlet flow and the unreacted fuel after the separation is circulated to a reformer, together with the above separated oxygen and is burnt in the reformer to be used as a heat source. As the result, liquid carbon dioxide, high purity nitrogen gas, and an argon gas product can be produced as by-products of the power generation.

摘要： PURPOSE: To find newly arising gas leakage under a condition where minute gas leakage unavoidably is present at many points by always processing measurements of a plurality of gas sensors and a plurality of anemometers by means of an arithmetic unit. CONSTITUTION: By assuming a plurality of leaking points 1-10 (numerals in squares) in a plant, the leaking amounts at the assumed leaking points are calculated by applying the measurements of gas sensors and anemometers during a fixed period of time in the past and coordinate values of the assumed leaking points to a gaseous diffusion equation. Then, the present theoretical values of the gas sensors are calculated from the present measurements of the anemometers on the leaking amounts. The differences between the theoretical values and the present actual values of the gas sensors are calculated. Thereafter, the fluctuating ranges of the filtered numerical values from the gas sensors due to the conventionally existing minute leakage are estimated by statistically processing the filtered numerical values from the gas sensors during a fixed period of time (e.g. 12-24 hours) and, when a larger filtered numerical value than the fluctuating width is obtained from a gas sensor, the occurrence of new leakage is recognized.

摘要： PURPOSE:To detect a new leak source accurately by a method wherein the statistic properties of a trace leak gas BGL is extracted and the BGL concentration estimated therefrom is removed from the concentration data or the variation thereof is monitored. CONSTITUTION:The time series data of BGL concentration measured by a plurality of high sensitivity sensors 20 set in a plant 40 is processed statistically along with the time series data of the speed and direction of wind measured by a wind speed/wind direction measuring apparatus 30 thus extracting the temporal/spatial properties of BGL inherent to the plant 40. The gas concentration estimated from the statistic properties is then subtracted from a gas sensor data sampled every moment and the time series of the difference is monitored or the statistic properties of BGL themselves are monitored thus detecting a new leakage. Furthermore, trade-off between the error rate and the missing rate can be managed rationally and reduced sufficiently through the simulation leak test of actual plant.

摘要： PURPOSE:To surely estimate the leakage point and leakage volume of gas, steam or the like with a high degree of accuracy. CONSTITUTION:A data processing device estimates a possible leakage existing position range in view of a real time variation of wind direction data and a positional relationship to sampling modules 10 even in such a condition that a measured density value from a sensor module 20 and a measured wind direction and a measured wind velocity from a wind direction and speed measuring device 30 have large error. Further, with the use of a verified relational expression which has been established among a leakage source position, a leakage volume and position of air introducing ports of the sampling modules 10, and time variations of wind direction and wind velocity data, and a density value of leakage medium which varies thereby, a leakage source position and a leakage volume are estimated within the estimated possible leakage source existing position range, most satisfying the relational expression, and the above- mentioned computation is repeated with the use of data which are further obtained as the time passes, subsequent to the detection of leakage.

摘要： PURPOSE:To obtain a highly reliable leakage sensing system such as gas and vapor, a method and an apparatus for measuring wind direction and speed. CONSTITUTION:Six sets of module sets M1 to M6 comprising a sampling module 10, a sensor module 20 and a wind direction/speed measuring device 30 are placed in a plant yard 40. An opening end of the sampling module 10 is sucked by a suction pump via the sensor module 20. From gas concentration in the atmosphere sensed by each sensor module 20 and collected by each sampling module 10, leakage of gas, vapor, etc., inside the plant is found with high probability. In addition, wind direction and speed data measured by the wind direction/speed measuring device 30 and the gas concentration sensed by the sensor module 20 are transmitted to a data processor, where a change in a leakage source existence possibility region is synthesized on a graphic screen to have a leakage source and a leakage amount estimated.
