Help! Regarding the issue of a significant discrepancy between the actual and theoretical production volume of crude benzene
Thread Content
The theoretical production method for crude benzene is as follows: (benzene content in the gas before the benzene washing tower minus benzene content in the gas after the tower) multiplied by the volume of gas processed during that shift gives the theoretical crude benzene production for that shift. The theoretically calculated values differ significantly from the actual production for that shift; since September, the actual production has been on average 1.3 tons lower, with the difference reaching up to 3.2 tons in some cases. Could someone help answer this? Is the calculation method incorrect, or is there indeed a loss of crude benzene?
First, it is necessary to check whether the test data (benzene content in the gas before and after the benzene washing tower) are accurate； Secondly, the benzene content in the gas before and after the benzene washing tower fluctuates; therefore, the theoretical crude benzene production cannot be calculated using data from a single instance or a single day. Instead, an average value over a certain period should be used for calculation. As long as there are no significant changes in the coal blending ratio or the type of coal used, this value will be fairly accurate ； Is the production process stable again, and is the control of process parameters optimal, given that Junhui has an impact on the crude benzene output?
Thank you for your reply. So, according to what you say, if the production process remains stable and there are no significant changes in the coal blending composition or the types of coal used, then over a certain period of time, should the theoretical output and the actual output be roughly the same?
