　　绿色能源生物天然气（丝瓜视频污版提纯）可行性报告

　　Feasibility Report on Green Energy Bionatural Gas (Biogas Purification)

　　1. 项目背景与意义1.1 政策支持国家“双碳”目标（2030碳达峰、2060碳中和）推动可再生能源发展。政策文件支持：《可再生能源法》《“十四五”生物经济发展规划》等明确鼓励丝瓜视频污版提纯利用。补贴与税收优惠：部分地区对生物天然气项目提供建设补贴或运营电价优惠。1.2 市场需求环保需求：替代化石能源，减少温室气体排放（甲烷的温室效应是CO的25倍，提纯后可减排）。能源需求：提纯后的生物天然气（甲烷含量≥95%）可直接并入天然气管网或作为车用燃料（CNG/LNG）。循环经济：农业废弃物（畜禽粪便、秸秆）、餐厨垃圾、工业有机废水等资源化利用。

　　1. Project background and significance 1.1 Policy support for the national "dual carbon" goals (2030 carbon peak, 2060 carbon neutrality) to promote the development of renewable energy. Policy documents support: The Renewable Energy Law and the 14th Five Year Plan for the Development of Bioeconomy explicitly encourage the purification and utilization of biogas. Subsidies and tax incentives: Some regions provide construction subsidies or operational electricity price discounts for biogas projects. 1.2 Market demand for environmental protection: Replace fossil fuels and reduce greenhouse gas emissions (methane has a greenhouse effect 25 times that of CO and can be purified to reduce emissions). Energy demand: Purified bio natural gas (methane content ≥ 95%) can be directly integrated into natural gas pipelines or used as vehicle fuel (CNG/LNG). Circular economy: Resource utilization of agricultural waste (livestock manure, straw), kitchen waste, industrial organic wastewater, etc.

　　2. 技术可行性2.1 工艺流程原料预处理：收集有机废弃物，进行除杂、粉碎、调质。厌氧发酵：在厌氧罐中产丝瓜视频污版（甲烷50%~70%，CO? 30%~50%，含少量H?S、水蒸气等）。丝瓜视频污版提纯：物理法：膜分离、PSA（变压吸附）、水洗法。化学法：胺吸收法（脱除CO?和H?S）。压缩储存：提纯后的生物天然气（CH?≥95%）压缩至20MPa或液化（LNG）。并网/应用：输入天然气管网、车用燃料或工业用途。

　　2. Technical feasibility 2.1 Process flow raw material pretreatment: Collect organic waste, remove impurities, crush, and adjust. Anaerobic fermentation: producing biogas (methane 50%~70%, CO ? 30%~50%, containing small amounts of H ? S, water vapor, etc.) in anaerobic tanks. Biogas purification: Physical methods: membrane separation, PSA (pressure swing adsorption), water washing method. Chemical method: amine absorption method (removal of CO ? and H ? S). Compressed storage: Purified biogas (CH ? ≥ 95%) is compressed to 20MPa or liquefied (LNG). Grid connection/application: Input natural gas pipeline network, vehicle fuel or industrial use.

　　3 环境与社会效益3.1 减排效益年处理10万吨畜禽粪便可减排CO?约5万吨/年。减少H?S、NH?等污染物排放。3.2 社会效益解决农村有机废弃物污染问题。创造就业（原料收集、运维等岗位）。

　　3 Environmental and Social Benefits 3.1 Emission Reduction Benefits Processing 100000 tons of livestock manure per year can reduce CO ? emissions by approximately 50000 tons per year. Reduce emissions of pollutants such as H ? S and NH ∝. 3.2 Social benefits to solve the problem of organic waste pollution in rural areas. Create employment opportunities (such as raw material collection, operation and maintenance).

　　4. 风险与对策4.1 风险分析原料供应风险：季节性波动（如秸秆集中产生）。技术风险：提纯设备稳定性（如H?S腐蚀）。市场风险：天然气价格波动。4.2 应对措施签订长期原料供应协议。选择成熟提纯技术（如PSA+膜分离组合工艺）。申请绿色金融支持（如碳减排贷款）。

　　4. Risks and Countermeasures 4.1 Risk Analysis Raw Material Supply Risks: Seasonal Fluctuations (such as Concentrated Production of Straw). Technical risk: Stability of purification equipment (such as H ? S corrosion). Market risk: Fluctuations in natural gas prices. 4.2 Response measures: Sign a long-term raw material supply agreement. Choose mature purification technologies (such as PSA+membrane separation combination process). Apply for green finance support (such as carbon reduction loans).

　　5. 结论与建议可行：生物天然气项目符合政策导向，技术成熟，经济性逐步提升。建议：优先布局农业大省（河南、山东等）或工业园区（集中处理有机废水）。争取地方政府配套（如特许经营权、并网许可）。探索“丝瓜视频污版发电+提纯”多联产模式。

　　5. Conclusion and Suggestions Feasible: The bio natural gas project conforms to policy guidance, has mature technology, and gradually improves economic viability. Suggestion: Prioritize the layout of agricultural provinces (Henan, Shandong, etc.) or industrial parks (centralized treatment of organic wastewater). Strive for local government support (such as franchise rights, grid connection permits). Explore the multi generation mode of "biogas power generation+purification".
