沼氣提純的主流技術路線對比與優劣分析

　　Comparison and analysis of the advantages and disadvantages of mainstream technology routes for biogas purification

　　水洗法；利用CO?和H?S在水中溶解度高于CH?的特性進行洗滌分離；成本低、操作簡單；水耗大、CO?去除率不高、產生污水；適合中小型項目

　　Water washing method; Utilizing the higher solubility of CO? And H? S in water compared to CH? For washing and separation; Low cost and simple operation; High water consumption, low CO removal rate, and wastewater generation; Suitable for small and medium-sized projects

　　PSA變壓吸附：在高壓下CO?等被吸附，減壓后再釋放；無需水或化學品；CH?損失高（達10%）、設備要求高；適合中大型項目

　　PSA pressure swing adsorption: CO and other substances are adsorbed under high pressure and released after depressurization; No need for water or chemicals; CH? High loss (up to 10%) and high equipment requirements; Suitable for medium and large-scale projects

　　膜分離：利用CH?和CO?通過膜的擴散速率不同進行分離；模塊化強、適合分布式項目；膜壽命有限、一次提純難達標；適合中小型分布式

　　Membrane separation: Separation is achieved by utilizing the different diffusion rates of CH? And CO? Through the membrane; Strong modularity, suitable for distributed projects; The lifespan of the membrane is limited, and it is difficult to meet the standard for a single purification; Suitable for small and medium-sized distributed systems

　　化學洗滌（MEA）：胺類溶液吸收CO?，隨后再生；CO?去除率高，氣體純度好；系統復雜、耗能高；適合大型集中化項目

　　Chemical cleaning (MEA): Amine solution absorbs CO and then regenerates; High CO removal rate and good gas purity; Complex system and high energy consumption; Suitable for large-scale centralized projects

　　深冷法：利用不同氣體冷凝點不同進行分離；純度最高，可液化；投資大、能耗高；適合LNG項目、超大型工程

　　Cryogenic method: using different gas condensation points for separation; The highest purity, liquefiable; Large investment and high energy consumption; Suitable for LNG projects and mega projects

　　哪種技術路線解決沼氣提純問題比較好？

　　Which technological route is better to solve the problem of biogas purification?

　　選擇哪種技術路線取決于項目的具體需求，包括沼氣來源（雜質種類）、規模、最終產品要求和經濟預算。

　　The choice of technology route depends on the specific needs of the project, including the source of biogas (types of impurities), scale, final product requirements, and economic budget.

　　追求最高純度和回收率：對于需要將生物天然氣注入高標準管網，或用于制造綠色氫氣、驅動燃料電池的場景，變壓吸附（PSA）通常被認為是最佳選擇。拿QUADROGEN公司的Q-PSA來說，其核心技術之一就是先進的快速循環PSA，能夠實現極高的甲烷純度和回收率。

　　Pursuing the highest purity and recovery rate: For scenarios that require injecting bio natural gas into high standard pipelines, or for manufacturing green hydrogen and driving fuel cells, pressure swing adsorption (PSA) is often considered the best choice. Taking QUADROGEN's Q-PSA as an example, one of its core technologies is advanced fast cycle PSA, which can achieve extremely high methane purity and recovery rate.

　　中小型或撬裝式應用：對于空間有限、希望操作簡便、啟停靈活的農場或小型填埋場項目，膜分離技術因其模塊化和簡單的優勢而備受青睞。盡管甲烷損失率稍高，但其便利性在很多場景下更具吸引力。

　　Small and medium-sized or modular applications: For farms or small landfill projects with limited space, simple operation, and flexible start stop, membrane separation technology is highly favored due to its modular and simple advantages. Although methane loss rate is slightly higher, its convenience is more attractive in many scenarios.

　　大型穩定氣源且預算充足：水洗法因其運行的穩定和低成本，在歐洲一些大型項目中仍有廣泛應用，尤其是在對甲烷回收率要求不是最頂級的場景下。

　　Large and stable gas source with sufficient budget: The water washing method is still widely used in some large-scale projects in Europe due to its stable operation and low cost, especially in scenarios where methane recovery rate requirements are not the highest.

　　專業化和集成化是趨勢：目前，行業領先的解決方案通常不是單一技術，而是多種技術的集成。例如，先通過化學法或生物法進行初步的脫硫，再用冷凝法去除大部分VOCs和水分，最后采用PSA或膜分離進行核心的提純。QUADROGEN的C3P工藝（冷凝、轉化、捕獲、精煉）就是一個典型的多技術集成系統，通過組合拳的方式，精準地解決了不同種類的雜質，從而實現了其他單一技術難以達到的凈化深度和經濟性。

　　Specialization and integration are trends: currently, industry-leading solutions are usually not single technologies, but the integration of multiple technologies. For example, initial desulfurization is carried out through chemical or biological methods, followed by the removal of most VOCs and moisture through condensation, and finally the core purification is achieved through PSA or membrane separation. QUADROGEN's C3P process (condensation, conversion, capture, refining) is a typical multi technology integrated system that accurately solves different types of impurities through a combination of punches, thereby achieving purification depth and economy that other single technologies cannot achieve.

　　總而言之，變壓吸附（PSA）技術在綜合性能（純度、回收率）上表現最為出色，尤其適合高標準應用，而膜分離技術則在靈活性和中小型應用上更具優勢。 未來的發展方向將是更高效、更低成本的材料（如新型吸附劑和膜材料）以及更智能化的多技術集成系統。

　　In summary, pressure swing adsorption (PSA) technology performs the best in comprehensive performance (purity, recovery rate), especially suitable for high standard applications, while membrane separation technology has more advantages in flexibility and small and medium-sized applications. The future development direction will be more efficient and cost-effective materials (such as new adsorbents and membrane materials) as well as more intelligent multi technology integrated systems.
