如何选择合适的脱硫工艺？

　　How to choose a suitable desulfurization process?

　　综合考虑实际需求

　　Taking into account actual needs comprehensively

　　在选择沼气脱硫工艺时，不能只看某一个方面，要综合考虑多个因素。

　　When choosing a biogas desulfurization process, one should not only consider one aspect, but also take into account multiple factors comprehensively.

　　沼气流量和硫化氢浓度：如果沼气流量小、硫化氢浓度低，干法脱硫是不错的选择；如果流量大、浓度高，湿法脱硫和生物脱硫更合适。

　　Biogas flow rate and hydrogen sulfide concentration: If the biogas flow rate is small and the hydrogen sulfide concentration is low, dry desulfurization is a good choice; If the flow rate is high and the concentration is high, wet desulfurization and biological desulfurization are more suitable.

　　成本预算：干法脱硫前期投资相对较小，但运行成本高；湿法脱硫和生物脱硫前期建设成本高，但运行成本相对较低。要根据自己的资金情况，算好经济账。

　　Cost budget: The initial investment in dry desulfurization is relatively small, but the operating cost is high; Wet desulfurization and biological desulfurization have high initial construction costs, but relatively low operating costs. According to one's own financial situation, calculate the economic account well.

　　场地条件：场地有限的话，干法脱硫更节省空间；场地充足的情况下，可以考虑湿法脱硫和生物脱硫。

　　Venue conditions: If the venue is limited, dry desulfurization is more space saving; If there is sufficient space, wet desulfurization and biological desulfurization can be considered.

　　环保要求：如果对环保要求很高，希望实现绿色生产，生物脱硫无疑是最佳选择；如果对环保要求相对较低，干法脱硫和湿法脱硫也能满足基本需求。

　　Environmental requirements: If there is a high demand for environmental protection and green production is desired, biological desulfurization is undoubtedly the best choice; If the environmental requirements are relatively low, dry desulfurization and wet desulfurization can also meet basic needs.

　　参考实际案例

　　Refer to actual case studies

　　我们来看几个实际案例。某小型养殖场，每天产生沼气 100 立方米，硫化氢浓度为 200ppm。经过综合考虑，选择了干法脱硫工艺。因为它处理量小，干法脱硫运行简单、占地面积小，而且能满足脱硫要求，虽然运行成本高一些，但整体比较合适。

　　Let's take a look at a few practical cases. A small livestock farm produces 100 cubic meters of biogas per day with a hydrogen sulfide concentration of 200ppm. After comprehensive consideration, the dry desulfurization process was chosen. Because of its small processing capacity, simple operation and small footprint of dry desulfurization, and ability to meet desulfurization requirements, although the operating cost is higher, it is generally more suitable.

　　再比如，某大型垃圾填埋场，每天产生沼气 5000 立方米，硫化氢浓度高达 1500ppm。这种情况下，采用了湿法脱硫工艺。湿法脱硫处理量大、脱硫效率高，虽然装机功率高、设备复杂，但能有效处理大量高浓度硫化氢的沼气。

　　For example, a large landfill produces 5000 cubic meters of biogas per day, with a hydrogen sulfide concentration as high as 1500ppm. In this case, wet desulfurization process was adopted. Wet desulfurization has a large processing capacity and high desulfurization efficiency. Although it has high installed power and complex equipment, it can effectively treat a large amount of high concentration hydrogen sulfide biogas.

　　还有一家注重环保的企业，同样是处理大量高浓度硫化氢的沼气，它选择了生物脱硫工艺。生物脱硫虽然启动时间长、对运行条件要求高，但它环保无污染、全自动运行，符合企业的发展理念。

　　There is also an environmentally friendly enterprise that processes a large amount of high concentration hydrogen sulfide biogas and chooses the biological desulfurization process. Although biological desulfurization has a long start-up time and high requirements for operating conditions, it is environmentally friendly, pollution-free, and operates fully automatically, which is in line with the development philosophy of the enterprise.

　　合理制定脱硫效果

　　Reasonably formulate desulfurization effect

　　在制定脱硫效果时，要根据后续设备对硫化氢浓度的限制来确定。比如，如果后续使用沼气的设备是锅炉或发电机，它们对硫化氢浓度有一定的要求，过高的硫化氢会腐蚀设备，影响设备寿命和运行安全。同时，还要考虑沼气与天然气消耗量的比例，制定一个合理的脱除效果。一般来说，我们建议最终的硫化氢含量控制在 25 - 100ppm，这样既能满足设备的使用要求，又不会过度脱硫增加成本。

　　When formulating the desulfurization effect, it should be determined based on the limitations of subsequent equipment on hydrogen sulfide concentration. For example, if the equipment that uses biogas in the future is a boiler or generator, they have certain requirements for hydrogen sulfide concentration. Excessive hydrogen sulfide can corrode the equipment, affecting its service life and operational safety. At the same time, it is necessary to consider the ratio of biogas and natural gas consumption and develop a reasonable removal effect. Generally speaking, we recommend that the final hydrogen sulfide content be controlled at 25-100ppm, which can meet the requirements of equipment use without excessive desulfurization and increasing costs.

　　沼气脱硫工艺各有千秋，没有绝对的好坏之分，只有适不适合的区别。通过了解它们的工作原理、适用范围、优缺点，以及如何选择合适的工艺，相信大家对沼气脱硫有了更深入的认识。在实际应用中，一定要结合自身的实际情况，综合考虑各种因素，选择最适合自己的脱硫工艺，让沼气这个清洁能源更好地为我们服务。

　　Each biogas desulfurization process has its own advantages, and there is no absolute distinction between good and bad, only the difference between suitability and unsuitability. By understanding their working principles, scope of application, advantages and disadvantages, as well as how to choose suitable processes, I believe everyone has a deeper understanding of biogas desulfurization. In practical applications, it is necessary to combine our own actual situation, comprehensively consider various factors, and choose the most suitable desulfurization process for ourselves, so that biogas, a clean energy source, can better serve us.
