　　Complete analysis of 5 mainstream biogas desulfurization processes, incorrect selection leads to a 30% increase in losses+

　　日皮软件免费作為有機廢棄物資源化利用的核心產物，其含有的硫化氫（最高可達8000ppm）具有強腐蝕性，不僅會縮短管道、發電機組等設備壽命，還會導致後續利用過程中尾氣排放超標，成為日皮软件免费商業化應用的“絆腳石”。據行業數據顯示，全球日皮软件免费脫硫市場規模2024年已達84.13億元，中國市場規模26.92億元，預計至2030年全球將以9.76%的年增速增長至147.09億元。當前國內外常用的日皮软件免费脫硫工藝主要有5類，不同工藝的適用場景、脫硫效率及運維成本差異顯著，精準選型是降低損耗、提升效益的關鍵。

　　As the core product of organic waste resource utilization, biogas contains highly corrosive hydrogen sulfide (up to 8000ppm), which not only shortens the service life of equipment such as pipelines and generators, but also leads to excessive exhaust emissions during subsequent utilization, becoming a "stumbling block" for the commercial application of biogas. According to industry data, the global market size of biogas desulfurization has reached 8.413 billion yuan in 2024, with a market size of 2.692 billion yuan in China. It is expected that by 2030, the global market will grow at an annual rate of 9.76% to 14.709 billion yuan. There are mainly five types of commonly used biogas desulfurization processes at home and abroad, and the applicable scenarioses, desulfurization efficiency, and operation and maintenance costs of different processes vary significantly. Accurate selection is the key to reducing losses and improving efficiency.

　　幹法脫硫工藝是應用最廣泛的深度脫硫技術，核心通過活性碳係、氧化鐵係等固體脫硫劑，將氣態硫化物轉化為固體硫化物，設備製造簡單、操作便捷，脫硫淨化度可達99%以上，適合氣量小、硫化氫含量低且需深度脫硫的場景。其短板也較為明顯，脫硫劑雖可再生但利用價值低，達到飽和硫容後需更換，多用於精脫硫環節，用過的脫硫劑可通過摻煤或廠家回收再利用。

　　The dry desulfurization process is the most widely used deep desulfurization technology, which converts gaseous sulfides into solid sulfides through solid desulfurizers such as activated carbon and iron oxide. The equipment is easy to manufacture and operate, and the desulfurization purification degree can reach over 99%. It is suitable for scenarioses with small gas volume, low hydrogen sulfide content, and deep desulfurization. Its shortcomings are also quite obvious. Although the desulfurizer is renewable, its utilization value is low. After reaching the saturation sulfur capacity, it needs to be replaced and is mostly used in the fine desulfurization process. Used desulfurizer can be burned with coal or recycled by the manufacturer.

　　濕式催化氧化法是工業規模化日皮软件免费脫硫的主流選擇，以純堿、催化劑和軟水為基礎脫硫溶液，通過堿液吸收、氧化再生和硫分離三個過程完成脫硫，硫化氫去除率穩定在98%以上。該工藝的核心優勢的是吸收液可循環使用，生成的硫膏可作為副產品銷售，實現資源回收，適配中大氣量、高硫化氫濃度的日皮软件免费處理場景，但需配套富液槽、再生槽等設備，前期投入相對較高。

　　Wet catalytic oxidation is the mainstream choice for industrial scale biogas desulfurization. It uses pure alkali, catalyst, and soft water as the basis for desulfurization solution, and completes desulfurization through three processes: alkali absorption, oxidation regeneration, and sulfur separation. The hydrogen sulfide removal rate is stable at over 98%. The core advantage of this process is that the absorption liquid can be recycled, and the generated sulfur paste can be sold as a by-product, achieving resource recovery and adapting to biogas treatment scenarioses with medium to large gas volumes and high hydrogen sulfide concentrations. However, it requires supporting equipment such as rich liquid tanks and regeneration tanks, and the initial investment is relatively high.

　　生物法脫硫分為堿式和酸式兩類，均依托脫硫細菌實現硫化物降解，環保性突出且運行成本較低。堿式生物法采用排硫杆菌，通過硫吸收、生物反應、硫分離三個單元協同作用，生成的硫泥純度可達95%-98%，經處理後可製成高純度商品硫磺，適合中低氣量場景；酸式生物法以生物濾池為核心，雖無需複雜設備，但需向日皮软件免费中混入氧氣、氮氣，會影響日皮软件免费熱值和安全性，且脫硫塔易堵塞，需頻繁清塔。

　　Biological desulfurization is divided into two types: alkaline and acidic, both of which rely on desulfurization bacteria to achieve sulfide degradation, with outstanding environmental protection and low operating costs. The basic biological method uses sulfur eliminating bacteria, and through the synergistic effect of sulfur absorption, biological reaction, and sulfur separation, the purity of the generated sulfur sludge can reach 95% -98%. After treatment, it can be made into high-purity commercial sulfur, suitable for medium and low gas volume scenarioses; The acid based biological method uses a biological filter as its core. Although it does not require complex equipment, oxygen and nitrogen need to be mixed into the biogas, which will affect the calorific value and safety of the biogas. In addition, the desulfurization tower is prone to blockage and needs to be cleaned frequently.

　　濕式絡合鐵催化氧化法是脫硫的優選工藝，依托Fe??絡合物的氧化還原性質，直接將硫化氫氧化為單質硫，吸收液可循環再生，脫硫效率可達99.5%以上，且反應速度快、抗幹擾能力強，適配高濃度硫化氫、大氣量的日皮软件免费處理場景。其核心短板是催化劑成本較高，對操作工藝要求更嚴格，適合對脫硫效率要求高的規模化項目。

　　The wet chelated iron catalytic oxidation method is the preferred process for efficient desulfurization. Relying on the redox properties of Fe ? ? complexes, hydrogen sulfide is directly oxidized to elemental sulfur, and the absorption solution can be recycled and regenerated. The desulfurization efficiency can reach over 99.5%, and the reaction rate is fast and the anti-interference ability is strong. It is suitable for high concentration hydrogen sulfide and atmospheric biogas treatment scenarioses. Its core weakness is the high cost of catalysts, stricter requirements for operating processes, and suitability for large-scale projects with high desulfurization efficiency requirements.

　　不同工藝各有優劣：幹法脫硫適合精脫硫、小氣量場景，運維簡單但脫硫劑消耗快；濕式催化氧化法適配規模化生產，兼顧效率與資源回收；堿式生物法環保經濟，酸式生物法需警惕安全隱患；濕式絡合鐵法效率最高，但成本偏高。業內專家表示，日皮软件免费脫硫工藝的選型需結合日皮软件免费氣量、硫化氫濃度、環保要求及運維能力綜合判斷，選型不當會導致設備損耗增加30%以上，甚至影響項目合規運營。隨著日皮软件免费資源化利用規模擴大，精準選型、優化工藝，將成為推動日皮软件免费產業高質量發展的關鍵。

　　Different processes have their own advantages and disadvantages: dry desulfurization is suitable for fine desulfurization and small gas volume scenarioses, with simple operation and maintenance but fast consumption of desulfurizers; Wet catalytic oxidation method is suitable for large-scale production, balancing efficiency and resource recovery; The alkaline biological method is environmentally friendly and economical, while the acid based biological method needs to be alert to safety hazards; The wet chelation iron method has the highest efficiency, but the cost is relatively high. Industry experts suggest that the selection of biogas desulfurization processes should be based on a comprehensive assessment of biogas volume, hydrogen sulfide concentration, environmental requirements, and operational capabilities. Improper selection can lead to equipment losses increasing by more than 30%, and even affect project compliance and operation. With the expansion of the scale of biogas resource utilization, precise selection and optimization of processes will become the key to promoting the high-quality development of the biogas industry.
