膜分離技術,被認為是21世紀工業技術改造中的一項極為重要的技術。隨著性能優異的新型膜材料不斷涌現,進一步開發出用于沼氣脫碳的高效低成本膜分離技術,將有助于推薦生物燃氣產業的發展。
Membrane separation technology is considered to be an extremely important technology in the industrial technological transformation in the 21st century. With the emergence of new membrane materials with excellent performance, further development of high-efficiency and low-cost membrane separation technology for biogas decarbonization will be helpful to recommend the development of biogas industry.
沼氣膜分離是指在壓力差為推動力的作用下,利用沼氣中各組分在氣體分離膜中滲透速率的不同而達到分離純化CH4的目的。
Biogas membrane separation refers to the separation and purification of CH4 by using the different permeation rates of components in biogas in the gas separation membrane under the driving force of pressure difference.
當無液態水、無油的壓縮沼氣沿中空纖維管內腔流動時,各種氣體的分壓在中空纖維絲管的高壓側(原料側)與低壓側(滲透側)所形成的驅動力——分壓差作用下,溶解系數和擴散系數大的氣體(如CO2)優先通過管壁,其余氣體(CH4)相對受到阻隔,從而達到分離的目的。
When the compressed biogas without liquid water and oil flows along the inner cavity of the hollow fiber tube, the partial pressure of various gases is formed by the driving force differential pressure between the high-pressure side (raw material side) and the low-pressure side (permeation side) of the hollow fiber tube, and the gas with large dissolution coefficient and diffusion coefficient (such as CO2) preferentially passes through the tube wall, and the other gases (CH4) are relatively blocked, so as to achieve the partial pressure The purpose of departure.
