Transplant of computer application software of high-pressure digestion system

The process of Bayer high pressure digestion, the physical meaning of realizing RP control block diagram by computer internal module and the mathematical model in RP control are briefly introduced. This control system, which plays an important role in alumina production, is the key item in alumina industry at home and abroad. On the basis of original import, our technical personnel have made the safe transition for process production by replacing the old computer system and partially modifying the original application software. The hardware configuration of the system and the differences between the old system and the new one are also introduced. The key to the conversion from the old software to the new one is explained by example.
