| Abstract: | Taking the rectification recycling of the ammonia with impurities in the process of indigotine production as an example, according to the feature that regulation of press is fast and the temperature is so lagging and has large disturbance in control process, established an optimizing control arithmetic based on concentration curve tracking method for distillation process and designed a decoupler to eliminate effect of temperature loop on pressure loop. The method has been used practically and the results prove the characteristics of high control precision and strong anti-disturbance capacity. |
| Keywords: | ammonia recycling rectification concentration curve tracking floating pressure control |
