Strengthen process management to ensure the long-term stable operation of the desulfurization process

Thread Content

The desulfurization process may seem simple, but the internal mechanisms involved are actually very complex, and there are many factors that affect it. Therefore, those responsible for the management and engineering of desulfurization processes should focus on process management. For desulfurization, the saying \"three parts technology and seven parts management\" is by no means an exaggeration; strengthening the technical management of this process is also the foundation and key to ensuring the stability of the desulfurization system. Specifically, the following tasks need to be carried out: 1. Management of the components in the desulfurization solution. The composition of the desulfurization liquid is not only related to the efficiency of desulfurization and the amount of purification materials consumed, but it also reflects whether there are any issues with the desulfurization unit during operation. Therefore, it can be said that process management in desulfurization primarily involves managing the composition of the desulfurization liquid. 2. Management of catalyst addition. The continuous addition of catalyst ensures low fluctuations in catalyst concentration, maintaining stability. 3. Management of regeneration. The management of regeneration involves closely observing the morphology of the sulfur foam, and identifying the problems in the system based on the different forms of this foam. The main factors affecting it include the regeneration temperature, the amount of air used for regeneration, and the content of secondary salts in the desulfurization solution. For trough-type regeneration, special attention should be paid to the air intake volume of the ejector and the blockage in the mixing tube. For high-tower regeneration, focus should be placed on the flotation of sulfur foam and the liquid level in the top tank. It is not sufficient to adjust the liquid level in the regeneration tank by increasing or decreasing the air volume in order to achieve sulfur foam flotation and overflow; the correct approach is to use a level controller to control the flotation of sulfur foam while maintaining stable flow rates for both the desulfurization liquid and the air, thereby ensuring stability in the regeneration process and proper flotation of sulfur foam. 4. Management of sulfur recovery. The sulfur recovery rate can directly reflect the regeneration condition; if it decreases, the cause must be identified and addressed promptly to prevent tower blockage accidents. 5. Management of process accidents. Process accidents can occur in the desulfurization system, such as a decrease in desulfurization efficiency, low sulfur recovery rates, rapid increase in by-product salts, high catalyst consumption, and tower blockages. This also includes accidents that occur prior to desulfurization, such as the shutdown of electrostatic tar collectors. Desulfurization technology managers must organize staff to promptly identify the causes of these accidents, determine appropriate solutions, and establish corrective and preventive measures to avoid similar incidents from occurring again. To ensure the long-term stable operation of the desulfurization system, proper management of the desulfurization process is crucial. The deterioration of the desulfurization process is a gradual process of cumulative changes; the reasons behind it are complex, with numerous influencing factors – including equipment configuration issues as well as management problems. If these issues are not identified and addressed in a timely manner, and if certain irregular practices and incorrect operating methods are not corrected promptly, over time this will lead to chaos in the desulfurization process. Therefore, effective management of desulfurization process technology is essential to ensure the long-term and stable operation of the desulfurization system!
