| Abstract: | The controlling of carbonation in soda production was carried out in two stages that first one conventional instruments were replaced with DCS to control and manage the production,and second one the controlling process was optimized with steering computer.The mainly controlling objects of the first stage were pressure of CO 2 mainpipe of lower part,bottom pressure of carbonation tower and the output of soda.The mathematics model of carbonation tower was built up and the running diagram of the computer was given. |
