To further standardize the nitrogen inflation procedure for cooling and heat exchange equipment and prevent accidents, the following regulations regarding this procedure are established; please comply with them: 1. Under normal operating conditions, if the cooling efficiency of such equipment declines due to factors such as mud accumulation or scaling, and it is not possible to shut down the equipment for cleaning promptly, then the nitrogen inflation procedure should be carried out. 2. For nitrogen inflation operations, low-pressure nitrogen must be used as the source of nitrogen. In case special circumstances require the use of medium-pressure nitrogen for such purposes, a written report from the workshop where the equipment is located is necessary, and approval from the Production Department must be obtained before proceeding. 3. Nitrogen inflation is prohibited for the cylinder jackets of all reciprocating compressors in the company. 4. The nitrogen injection operation must be carried out by at least two persons (one responsible for operating the nitrogen valve and the other for monitoring the heat exchange equipment), and it can only be conducted with the approval of the control room. 5. During nitrogen charging, the exhaust and drain valves of the circulating water system must be fully open to prevent air blockages. The upper return water valve should be controlled based on actual conditions on site, but it must not be completely closed. 6. Records of the process conditions of the equipment and system before and after the nitrogen injection operation should be kept (as recorded in the workshop’s ‘Process Measurement Logbook’) in order to compare the effects. 7. When using a medium-pressure nitrogen drum to supply nitrogen, it is necessary to strictly control the pressure on the circulating water side so that it does not exceed the designed pressure of that side of the equipment, and to ensure proper flow of the circulating water. Is the above reasonable? Please share your insights
