Oil Purification Reaction-node Monitoring

Collapsed Manual Control Window: Traditional reaction nodes rely on manual judgment, resulting in slow response. In oil purification processes, workers typically observe the reactor color every 15 minutes and record data, requiring at least 5 minutes from observation to decision. If the reaction progresses rapidly between intervals, the optimal control point may be missed. For example, a refinery once experienced a 20-minute delay in manual judgment, causing excessive desulfurization.

Experience Variability Undermines Process Stability: Manual judgments are prone to errors due to differences in experience and observation. Inconsistent assessments between workers can cause reaction node misjudgment. For instance, in a hydrofining reaction, a 10-year veteran might determine the node at 120 minutes, while a 5-year worker might judge 110 minutes, creating significant deviation. A company once faced three faulty oil purification batches due to a new employee's misjudgment.

Delayed Node Response Leads to Impurity Formation: Lagging reaction node determination affects oil purification quality. If temperature and pressure adjustments are delayed, impurities may remain or new ones may form due to overreaction. For example, one gasoline batch failed to meet sulfur standards due to delayed judgment, requiring reprocessing and raising production costs.
