摘要： In a nondestructive inspection of a defect of a welded portion of a pipe or a pipe member, work efficiency of a radiation transmission test is improved by reducing a burden on a worker, and an inspection accuracy is improved. Imaging data is acquired by transmitting radiation through a welded portion of the pipe to be inspected. Processing of associating determination data indicating a result of determining a defect of the welded portion of the pipe to be inspected based on a distribution of a transmission intensity of the radiation obtained from the imaging data with image data showing the distribution of the transmission intensity of the radiation is performed. As a result, through use of the imaging data, image data and determination data associated with the image data can be obtained, and the burden on the worker can be reduced.

摘要： A natural gas liquefying apparatus is provided. At least a part of a cooling region, in which a precooling unit and a liquefaction unit are arranged, and at least a part of a compression region, in which first and second compressors compressing refrigerants to be used in the precooling unit and the liquefaction unit are arranged, are arranged to be opposed to each other across a long side of a second refrigerant cooler group arrangement region in which a liquefying refrigerant is cooled. A first refrigerant cooler group arrangement region, in which a precooling refrigerant is cooled, is arranged so that a long side of the first refrigerant cooler group arrangement region is opposed to one side of a rectangular region including the compression region, the one side being different from a side of the rectangular region opposed to a long side of the second refrigerant cooler group arrangement region.

摘要： A calculation unit acquires first to third prices that are sales unit prices of a first product, a second product, and power generated by a power generation device. Based on at least one of the first to third prices, the calculation unit determines a first supply amount of the first product to a sales means, a second supply amount of the first product to a second manufacturing device, and a third supply amount of the first product to the power generation device. A control signal output unit outputs a control signal such that the first product is supplied to the sales means at the determined first supply amount, the first product is supplied to the second manufacturing device at the determined second supply amount, and the first product is supplied to the power generation device at the determined third supply amount.

摘要： A clustering method includes the steps of: creating a plant model in which connection relationships between a plurality of devices (31) forming a processing plant (1) and pipes (4) are represented by a graph showing a linking relationship between a node (51) and an edge (52); setting, regarding the plant model, a cluster division condition; and performing, by a computer, the cluster division of the plant model by searching for an edge between the clusters in which modularity is further increased while the cluster division condition is satisfied.

摘要： A natural gas pretreatment system includes: a carbon dioxide removal unit configured to remove carbon dioxide from the natural gas by bringing an absorption liquid and the natural gas into contact with each other; and a water removal unit configured to remove water by causing the natural gas to flow through a packed bed containing a water adsorbent. The packed bed contains a carbon dioxide adsorbent for adsorbing and removing the carbon dioxide that has not been completely removed in the carbon dioxide removal unit, and a concentration of the carbon dioxide contained in the natural gas is measured by an outlet-side carbon dioxide measurement unit on an outlet side of the water removal unit.

摘要： In a method of operating an adsorption apparatus including a plurality of adsorption beds each packed with a physical adsorbent, when an adsorption step is performed in a part of the adsorption beds and another adsorption bed is to be regenerated, after the adsorption target component adsorbed on the physical adsorbent is desorbed, a gas for cooling is caused to flow through the another adsorption bed so that the another adsorption bed is cooled until an outlet temperature of the another adsorption bed reaches a temperature set in advance. Further, the cooled adsorption bed stands by for switching to the adsorption step while a gas for standby for maintaining a cooled state is caused to flow through the cooled adsorption bed.

摘要： A methane gas production facility or the like capable of efficiently producing a methane gas from a wide range of a methane hydrate layer. In a methane gas production facility that produces a methane gas from a methane hydrate layer MHL, a first horizontal well is provided along the methane hydrate layer MHL and injection water supply units supply injection water obtained by dispersing a carbon dioxide gas in water to the first horizontal. well. A second horizontal well is provided along an area in which methane released from methane hydrate by replacement with carbon dioxide rises, a decompression and suction unit decompresses the inside of the second horizontal well by pumping water and sucks water containing methane, and a gas-liquid separation unit separates a methane gas from the sucked water.
