How do you organize the initial startup steps for chemical fertilizers?

1. General principles for commissioning: General principles for starting up the plant: Ensure successful commissioning on the first attempt. 2. Develop a plan and contact relevant departments. 3. Purge the system after maintenance is completed. 3.1 Purge the instrument air pipelines. 3.2 Purge the air pipelines. 3.3 Purge the fuel gas pipelines. 3.4 Purge the process gas pipelines. 3.5 Purge the steam pipelines. 4. Perform airtightness testing and pressure testing of the system. 4.1 Contact the dispatch team to establish the N5, N80, and N120 pipeline networks. 4.1.1 Establish the N5 pipeline network. 4.1.2 Establish the N80 pipeline network. 4.1.3 Establish the N120 pipeline network. 4.2 Perform airtightness testing and pressure testing of the fuel gas system. 4.3 Perform airtightness testing and pressure testing of the process gas system. 4.4 Perform pressure testing with water in the water system. 5. Purging. 5.1 Purge the fuel gas system. 5.2 Purge the process gas system. 6. Requirements for personnel involved in commissioning. 6.1 Provide timely and accurate instructions. 6.2 The operation was carried out properly and without errors. 6.3 Key steps are supervised by designated personnel. 6.4 State change – three-level inspection (operator, team, workshop). 6.5 Throughout the startup process, it is essential to adhere strictly to the “eleven no’s”: no oil leakage, no overspeeding, no fires, no overpressure, no gas leakage, no overheating, no vacuum conditions, no insufficient liquid level, no explosions, no defective products, and no water in the steam pipeline system.

The initial commissioning of a fertilizer plant generally involves the following steps: 1. Conduct individual unit tests in separate sections, clean and purge them, and perform pressure testing to check for leaks； 2. Conduct water and gas linkage testing in segments ； 3. If necessary, conduct a system-wide water and gas integrated test run ； 4. Perform a full-system replacement, heat the catalyst for reduction, and start production once the conditions are met. Organizational measures should include: 1. Formulating a scientific and detailed driving plan ； 2. Establish a driving leadership team to clarify responsibilities and requirements, and provide unified command ； 3. Establish startup command teams for each work section, which are responsible for carrying out the normal startup procedures ；

General steps for the initial commissioning of fertilizer production plants: 1. Clean up debris on the work surfaces in various areas, and blow out any dust from the welded and repaired pipeline equipment; conduct pressure tests to check for leaks, and carry out individual tests for each section separately. 2. After the individual unit tests for purging and cleaning in each section are completed, a comprehensive water and gas integrated test of the entire system is carried out (our company uses air, with a maximum pressure of 2.5 MP). 3. Light the boiler and gas generator to produce inert gas for purging the entire system. 4. Heat or reduce the catalyst; after the heating or reduction is complete, switch to light load or normal operation. The production organization department should: establish a startup leadership team and clarify responsibilities and requirements ； Develop a scientific and detailed driving plan ； (Scheduling Department) Unified command ； Establish start-up command teams for each work section to be specifically responsible for the normal start-up operations.
