What type of DCS is used for the 200,000-ton synthetic ammonia with methanol co-production project?
Thread Content
What kind of DCS system and equipment are suitable for a 200,000-ton synthetic ammonia with methanol co-production project? Experts, please give me some recommendations; I’m a beginner! The normal operation control and monitoring of the gasification unit are implemented in the DCS, while the safety interlock protection is implemented in the ESD; other control devices do not use the ESD. Please share your suggestions. Advanced technology, reasonable cost, reliable operation, and easy handling – these are the requirements set by the boss! Give me a rough price!
To be honest, your proposal is too broad – it can be implemented both domestically and internationally; the key lies in the leadership’s investment budget
500,000: domestic DCS systems, including Hilscher, Zhejiang University Control System, and Shanghai Xinhua
If the budget is low, domestic control systems from the chemical industry will suffice; if the budget is a bit higher, Yokogawa’s products from Japan offer good software and hardware as well as satisfactory performance. For even higher budgets, Honeywell or Emerson are great choices – haha, they’re all very good systems
I don’t understand the stuff, let alone the boss! How are domestic systems performing in terms of ESD in the chemical industry?
Ammonia synthesis involves high temperatures and pressures, complex processes, and requires high precision in control； If you, as the owner of the building, are only responsible for purchasing the equipment without taking care of its maintenance later on, then domestic products could be a consideration. But if you’ll be in charge of its maintenance as well, I’d recommend going with imported products, even though they cost about 50% more. Recommendations: 1. Hoeywell PKS + SM 2. Yokogawa CS3000 + TRICON 3. Foxboro (I’m not very familiar with this brand, hehe) 4. Emerson
How is the system used in China performing in terms of ESD in the chemical industry? There is no true ESD available in the domestic market; it’s better to import it
