Description

[0002] In order to reduce costs, solvent consumption and environmental pollution, the production process of tetrabromobisphenol A (TBBPA) generally adopts a high recycling mode of organic solvents such as chlorobenzene.

[0003] As the number of solvent cycles increases, impurities accumulate in the reaction system, leading to three interconnected process challenges: (1) Deterioration of crystal morphology: The enrichment of impurities causes the growth of tetrabromobisphenol A crystals to change from "single crystal expansion" to "dendritic aggregation", forming loose aggregates with fractal structure. The median particle size d50 of the crystal is often less than 250 μm, and the particle size distribution width σ increases significantly. (2) Slurry viscosity fluctuation: The oligomers in the impurities cause the slurry to exhibit non-Newtonian fluid characteristics. The apparent viscosity depends not only on the temperature, but also on the shear history. The viscosity fluctuation range can reach ±40%. (3) Difficulty in solid-liquid separation: The dynamic changes in material properties lead to unstable permeability of the filter bed, mismatch between separation driving force and resistance, and traditional fixed parameter control is difficult to adapt.

The test continuously processed five high-cycle batches, and the median particle size of the material was... The particle size distribution width fluctuates between 158 and 205 micrometers. It fluctuates within the range of 1.5-2.0.

[0032] The specific results are shown in Table 1: Table 1 Comparative Experiment Results

[0033] To quantitatively evaluate the long-term effectiveness of this invention, a system comparative test was conducted on a production line. The experimental group used the control method described in this invention, running continuously for 30 batches. The d50 of the material fluctuated within the range of 150-230 μm, and σ fluctuated within the range of 1.4-2.2. The statistical results are shown in Table 2. Table 2 Long-term operation results

[0034] The method proposed in this invention utilizes the interfacial tension gradient driven by the temperature difference between the solvent and the feed solution to enhance the mass transfer process of impurities from the crystal surface to the solvent.

[0035] Under typical high-cycle conditions (i.e., more than 20 cycles, with d50 in the range of 150-220μm), the following can be achieved: filter cake moisture content is consistently below 5%, reaching as low as 4.5% in the examples; product purity is better than 99.4%, reaching 99.62% in the examples; single-batch processing time is reduced by more than 12%; solvent consumption is reduced by more than 16%; and unit product power consumption is reduced by more than 19%.

[0037] The mechanical structure applied in this invention involves feeding high-cycle raw materials into the system via a feed pump. Simultaneously, real-time material characteristic data is acquired through an online density meter, temperature sensor, and online viscometer. This data, along with equipment operating status signals collected by vibration and torque sensors, is input into the horizontal screw centrifuge. The solid phase output from the centrifuge is sent to a near-infrared moisture analyzer for final quality determination, while the liquid phase output is sent to an online concentration meter for core quality feedback. Both equipment operating status and quality feedback data are transmitted to the control cabinet. The control cabinet, through an adaptive algorithm, outputs speed commands to the main motor driver, feed control signals to the horizontal screw centrifuge, frequency commands to the washing solvent tank B, and liquid inlet commands to the solvent B storage tank. Simultaneously, it interacts with the human-machine interface to control the entry of washing solvent A from the solvent A storage tank into the annular sprayer. The operating status signal of the annular sprayer is also fed back to the control cabinet. Finally, the system also treats the mother liquor discharged from the centrifuge through a mother liquor collection tank, achieving closed-loop control throughout the entire process.

[0038] The above data shows that even with significant fluctuations in feeding conditions, the present invention can still maintain a high degree of stability in product quality between batches.
