沼气作为一种很有前途的可再生能源，受到了广泛的关注。通过具有成本效益的途径将粗沼气升级为高纯度的生物甲烷可以促进热值和燃烧效率的提高。本文研究了一种新型膜-低温组合系统的沼气提质性能。测试了两种中空纤维膜（聚酰亚胺和聚砜）在不同操作温度下的分离性能，并根据实验数据进行了过程模拟。实验结果表明，低温下操作膜可以提高生物甲烷的纯度（聚酰亚胺和聚砜分别提高6.0%和6.8%），有利于膜与低温的结合。此外，模拟结果还表明，利用生物液化天然气（bio-LNG）的冷量，聚酰亚胺膜-低温复合工艺的总能耗可降低至0.8 MJ/kg-CH 4。可以观察到，所提出的新型膜-低温混合工艺可以是传统沼气提质技术的有竞争力的替代方案，以产生高质量（高达98%）的生物甲烷。
As a promising renewable fuel, biogas has been given widely attention. Upgrading raw biogas into high purity biomethane via a cost-effective route could facilitate the enhancement of heating value and combustion efficiency. In this study, biogas upgrading performance of a novel membrane-cryogenic hybrid system was investigated. The separation properties of two kinds of hollow fiber membranes (polyimide and polysulfone) were tested at different operating temperature, and then process simulation was conducted based on the experimental data. The experiment results indicated that operating membrane at the low temperature condition could be a potential method to improve biomethane purity (increased by 6.0% and 6.8% via polyimide and polysulfone, respectively), which was beneficial for combining membrane with cryogenic in the hybrid process. In addition, the simulation results showed that the total energy consumption of (polyimide) membrane-cryogenic hybrid process could be reduced to 0.8 MJ/kg-CH4, when the cold energy was recuperated from liquefied biomethane (bio-LNG). It could be observed that the proposed novel membrane-cryogenic hybrid process could be a competitive alternative for the conventional biogas upgrading technologies to produce high quality (up to 98%) biomethane.
