Commissioning plan after major overhaul of ammonia synthesis (reconstruction of the gas generator, pipe replacement for decarburization overhaul, pressure maintenance during methanol methanation synthesis)
This is relatively simple. Most factories have relevant information on this; you can check with your production technology department – it should be available there. There’s actually quite a lot to write down, but generally speaking, there’s no need for any major replacements when starting up the equipment in this case. It’s just a standard startup procedure after routine maintenance. Check the relevant documents; if you can’t find what you need, then get in touch with us
It can be written from the following aspects: 1. Preparations before driving, including checking each item on the maintenance list to ensure that all tasks have been completed to the required standard; verifying that the necessary instruments and chemicals are available, that the lighting facilities are in good condition, and that all valves are in their proper positions； 2. Individual test run of the pump unit ； Blowing and pressure/leak testing for specific positions ； 3. Prepare inert gas for displacement; it can be used to displace air at the inlet of the methanol unit ； 4. Adjust the catalyst heating temperature as appropriate; if there are two systems, consider using catalysts for methanol, methane, and ammonia for heating ； 5. The system starts production.
This is not a newly established factory; in this field, such factories should have a technical expertise accumulated over ten years or even several decades. Check the technical documentation kept in the factory’s archives.
