A method for transferring a cooling agent (H2) from a storage container (2) to a consumption source (3), comprising: a) a step S1 of introducing the cooling agent (H2) from the storage container (2) to a conditioning container (8, 9, 10); b) a step S2 of bringing the cooling agent (H2) contained in the conditioning container (8, 9, 10) to a supercritical state; and c) a step S3 of discharging the cooling agent (H2) from the conditioning container (8, 9, 10) to a consumption source (3), wherein the cooling agent (H2) contained in the conditioning container (8, 9, 10) is maintained in a supercritical state during step c), and a portion of the cooling agent (H2) is drawn out from the conditioning container (8, 9, 10) using a pressure rising system (28, 29, 30), heated, and then supplied back to the conditioning container (8, 9, 10) to bring it to a supercritical state. A method for transporting a refrigerant, wherein the refrigerant is maintained and contained in a volume (31, 33) of a pressure rising system (28, 29, 30), is trapped between valves (V5.1, V6.1; V5.1, V7.1) within the volume (31, 33), heat is supplied to the refrigerant trapped in the volume, and as soon as the desired target pressure of the trapped refrigerant is reached, the refrigerant is supplied back to a conditioning vessel (8, 9, 10).

FIELD: automated process control systems.SUBSTANCE: invention can be used to improve the efficiency of remote monitoring and diagnostics procedures, determine the condition and ensure reliable operation of process pipelines of compressor stations. The automated system for searching and monitoring vibration zones in process pipelines at compressor stations consists of a real-time database, a database of simulated templates of hazardous operating conditions with the risk of vibration occurring in pipeline sections, a module for identifying a section with the potential for vibration to occur in a process pipeline, a module for calculating the gas flow rate in a designated area of a process pipeline, a module for visualizing and tracking the predicted vibration level, and a module for issuing recommendations for reducing vibration levels. The proposed automated system is located in the central control centre. Information is fed into the real-time database from lower-level systems. Low-level systems include analogue pressure, temperature, and flow sensors, discrete position sensors for pipeline valves, and digital sensors for the state of pipeline valves.EFFECT: improved detection performance.1 cl, 5 dwg

To provide a technique for suppressing a load applied to a hydrogen tank in which a resin liner is laminated on an inner wall.SOLUTION: A control device according to a first aspect of the present disclosure includes a controller. The control unit is configured to detect, by the temperature sensor, a temperature of the hydrogen tank having the resin liner laminated on the inner wall when hydrogen is filled from the hydrogen filling device, determine whether the detected temperature of the hydrogen tank is lower than a predetermined temperature, and restrict filling of hydrogen when the temperature is lower than the predetermined temperature.SELECTED DRAWING: Figure 3

To provide a gas container improved in cooling performance.SOLUTION: A cooling device includes a container part 2 having an internal space 29, a cooling element including a plurality of cooling parts 4 arranged in the internal space 29, and a storage material 8 arranged between the cooling parts 4 adjacent to each other in the internal space 29 and occluding and releasing a filling gas, wherein the cooling part 4 has a tube part 5 extending in an axial direction of the container part 2 and having a heat exchange medium flowing therethrough, and a cooling fin part 6 protruding radially outward from an outer peripheral surface of the tube part 5. Wherein the internal space (29) includes a first region (FA) and a second region (SA) that is radially outward of the first region (FA) in the container portion (2) and has a larger radial cross-sectional area than the first region (FA), and the number of the cooling portions (4) in the second region (SA) is larger than the number of the cooling portions (4) in the first region (FA).SELECTED DRAWING: Figure 4

A cleaning method for a high-pressure gas container is provided that can suppress the generation of water inside the high-pressure gas container. The cleaning method for a high-pressure gas container comprises a depressurization process for depressurizing the inside of the high-pressure gas container until the internal pressure becomes 5 Pa or less, and a cleaning process for cleaning the inside of the high-pressure gas container after the depressurization process. The cleaning process comprises a hydrogen halide supply step for supplying hydrogen halide to the high-pressure gas container after the depressurization process, a metal oxide removal step for reacting the hydrogen halide supplied by the hydrogen halide supply step with the metal oxide present on the inner surface of the high-pressure gas container after the hydrogen halide supply step to generate water, and a discharge step for discharging the water generated in the metal oxide removal step and the hydrogen halide supplied by the hydrogen halide supply step from the high-pressure gas container.
