1. Strengthen the management of process parameters and equipment management to ensure long-term stability of the system and optimize its operation. 2. Control leaks, spills, drips, and leaks in the control system. 3. Increase the conversion rate of CO2.
1. Improve CO2 purity； 2. Lower the temperature of the recovery (absorption) liquid ； 3. Control the appropriate water-to-carbon ratio and ammonia-to-carbon ratio ； 4. Slightly increase the reaction pressure ； 5. Improve equipment output efficiency ； 6. The system operates safely and stably over long periods of time.
1. The water-to-carbon ratio and ammonia-to-carbon ratio should be appropriate. 2. The synthesis pressure needs to be high. 3. The temperature of the preheater can be increased slightly. 4. The purity of CO2 must be high. 5. The circulation volume should be controlled as much as possible
1 First, ensure the air delivery volume of the compressor. 2 Improve the purity of CO2 and the synthesis conversion rate. 3 The temperature of the preheater can be kept relatively low (compared to when the production load is lower). 4 Increase the load as much as possible, provided that the desorption or hydrolysis parameters remain within normal ranges. 5 Control any leaks or losses in the control system.
