Evaluation of transformation device process, capacity, and performance
Thread Content
Discuss the process, capacity, and performance evaluation of ammonia synthesis plants (including dihydrazine, etc.). Please share information on the scale of your shift unit, production process, design company, as well as your evaluation of that design company after its use. The format is as follows: (1) Production capacity (2) Production process (3) Designing unit (4) Evaluation
(1) Production capacity: 300,000 tons per year. (2) Production process: CO2 stripping method, medium-low-low shift unit. (3) Design agency: Chengda Design Institute. (4) Assessment: The project is currently under construction; any findings regarding issues can only be determined after the three inspections and four confirmations are completed.
(1) Production capacity: 80,000 tons per year； (2) Production process: Fully low-temperature shift process without a saturation tower ； (3) Design unit: Hubei Institute ； (4) Evaluation: Overall good, but the steam consumption is higher than expected. There are also two sets of self-made mid-string lows.
(1) Production capacity: 40,000 units per year. (2) Production process: Medium-string low-type. (3) Design unit: Hua Ba Yuan. (4) Evaluation: Outdated
(1) Production capacity: 120,000 units per year. (2) Production technology level: medium-low-low. (3) Design agency: Huasi Fourth Research Institute. (4) Evaluation: The performance is quite good
(1) Production capacity: 330,000 tons per year； (Two systems) (2) Production process: The old system does not feature the process of connecting low-pressure units within a saturation tower ； The new system features a medium-string low process with a saturated hot water tower. (3) Design unit: Inner Mongolia Xun Chemical Engineering Design Institute (4) Evaluation: It’s acceptable!
(1) Production capacity: 300,000 tons per year. (2) Production process: high and low voltage transformation process. (3) Design agency: Ningbo Design Institute. (4) Evaluation: Operates very stably, with excellent performance
