Dehydrogenation and hydrogenation
Thread Content
1. Hydrogen unloading: When unloading hydrogen, it is essential to ensure that the connecting hoses are properly fitted (with matching connectors and good sealing), so as to allow hydrogen to flow smoothly into the downstream pipelines, storage tanks, cylinder banks, etc. Once the unloading is complete, the valve at the hydrogen-unloading end should be closed first, and the hydrogen gas in the pipe between the two ends should be removed manually or automatically. This allows the hose to be removed under pressure-free conditions, ensuring the safety of the workers and the associated equipment. 2. Hydrogenation: When adding hydrogen, it is also necessary to ensure a proper connection between the filling equipment and the hydrogen injection equipment. Since hydrogenation is a process that involves an increase in temperature (with relevant standards requiring this temperature to be kept at 85 degrees), the filling rate must be taken into consideration during this process. After filling is complete, the residual hydrogen is vented through the built-in vent pipe on the filling gun.
When releasing hydrogen, ensure that the hoses are properly connected and sealed; after the release is complete, close the valve first before draining the hydrogen from the pipes. During hydrogenation, check the equipment connections, control the filling rate and temperature, and remove any residual hydrogen after completion. .
