On the significance of analyzing data for adjustments during desulfurization operations

Thread Content

Analyzing data is the manager’s eyes; the most direct approach is to let the data speak and use it to guide production and its adjustments. Some have all the necessary analyses, but they are not integrated with process adjustments and are not truly used to guide production ； Some analysis data is inaccurate and can even mislead production. Only timely and accurate analysis of data can effectively guide production in the right direction. For desulfurization, conventional analytical parameters such as pH, potential, density, catalyst concentration, alkalinity/volatile ammonia, and the content of by-products must be monitored on a daily or every-other-day basis. Some marginal data, such as the oxygen content in gas, the amount of oil and dust, the oil content and oxygen content in solutions, as well as viscosity, also need to be monitored regularly. The following outlines a few indicators that are not frequently monitored or that are closely related to desulfurization, with brief explanations: For example, the amount of HS- in the desulfurization solution. By comparing the HS- content in the lean solution and the rich solution, it is possible to understand the relationship between absorption, regeneration, and catalyst concentration; this can be adjusted by controlling the catalyst concentration and the amount of air used for regeneration. Another example is the oxygen content in the desulfurization liquid, which is also a parameter that is often overlooked. More dissolved oxygen isn’t necessarily better; too high a level leads to rapid formation of by-products, so it is necessary to reduce the oxygen content under process control by lowering the air flow rate or the amount of chemicals used. In some cases, this may result in reduced production, and adjustments must be made when the oxygen level in the air is too high. Similarly, the content of by-products must be monitored regularly and promptly; when it exceeds a certain level, it not only affects the desulfurization efficiency and foam flotation as well as causes equipment corrosion, but it can also lead to buildup and blockage of the packing. Every enterprise and manager must find indicators that suit them, paying attention to process adjustments. Managers fail to be meticulous in their work; they do not persist in comparing data, do not develop a habit of comparing various phenomena with data, and fail to form long-term memories of comprehensive information in their minds. It is not possible to acquire one’s own core expertise by simply observing more, thinking more, and accumulating experience over time. There is no best, only better; one must strive to improve through effort.
