Keeping proper records of data tracking is more beneficial for the operation of desulfurization units

Each set of hydrogen sulfide treatment and sulfur recovery systems represents valuable intangible assets; the operational data provided a solid foundation for technical improvements, supported problem analysis, and enabled tracing back to the origins of issues. For each set of equipment, it is necessary to keep track of daily data, monitor every parameter adjustment and optimization, understand the changes before and after such adjustments, determine whether the operating trend is positive or negative, and make predictions in advance to enable appropriate control. The key data that need to be monitored include: 1. The volume of feed gas and the hydrogen sulfide concentration at the inlet and outlet of the unit. These are used to assess the effectiveness of desulfurization and the amount of sulfur produced. When there are fluctuations in the hydrogen sulfide concentration at the outlet, it is necessary to identify the cause promptly and take corrective action ； 2. The purpose of monitoring the sulfur output of the plant is to determine whether sulfur production is in balance, based on the amount of sulfur generated by the plant. If this balance is not maintained over time, sulfur will accumulate within the plant, and measures need to be taken to increase sulfur output. 3. Overall liquid level of the device: The liquid level provides an intuitive indication of changes in the amount of liquid stored inside the device. If the liquid level in various components of the device tends to rise over time, it indicates an imbalance in the device’s water balance; in such cases, it is necessary to reduce the amount of water added or adjust the temperature to lower the liquid level and maintain a stable water balance. 4. Specific gravity of the solution: The specific gravity indicates whether the concentration of the desulfurization solution is increasing or decreasing. Under normal conditions, it remains stable within a certain range; if it rises suddenly and rapidly on a continuous basis, it is necessary to analyze the specific reasons by considering water balance and sulfur production ； If the water balance is normal and sulfur production is normal, it may be that unstable operation has led to an increase in side reactions, posing a risk of the accumulation of by-products; in such cases, a case-by-case analysis is required.
