Abstract

As a result of rising economies and environmental constraints, the demand for clean and renewable sources of energy is fast increasing. Biogas is a renewable form of energy that fits all expectations in terms of delivery, cost, and greenhouse emissions reduction. Biogas utilization is advantageous because it is a means of creating wealth from daily human, agricultural, household and municipal waste that could otherwise be polluting the environment as waste is deposited on a daily basis which are potential biogas sources; it is not dependent on weather conditions as other renewable forms (solar and wind). Biogas can also be compressed, stored and transported, and therefore easily responds to changes in demand. This paper entails the use of nano-structured membranes to upgrade biogas (which contains primarily methane and carbon dioxide). The benefits of membranes include their compact structure and ease of usage with low maintenance, their low running costs and minimal loss of the upgraded gas. 15nm, 200nm and 6000nm membranes were used to ascertain the flux of the model biogas mixture passing through it under various operating conditions. In each case, the exit flowrate of methane was higher than that of carbon dioxide and this is attributed to the pore sizes of the membrane and its ability to filter the heavier gases. The results show that the molecular weight of the gases also play a role in their permeation rate as it follows the Knudsen regime.
孔径和温度对纳米陶瓷膜中气体输运影响的对比评价
由于经济增长和环境限制,对清洁和可再生能源的需求正在迅速增加。沼气是一种可再生能源,在运输、成本和减少温室气体排放方面符合所有人的期望。沼气的利用是有利的,因为它是一种从日常的人类、农业、家庭和城市废物中创造财富的手段,否则这些废物可能会污染环境,因为这些废物是潜在的沼气来源;它不像其他可再生能源(太阳能和风能)那样依赖于天气条件。沼气也可以被压缩、储存和运输,因此很容易应对需求的变化。这篇论文需要使用纳米结构膜来升级沼气(主要含有甲烷和二氧化碳)。膜的优点包括结构紧凑,易于使用,维护费用低,运行成本低,升级气体的损失最小。采用15nm、200nm和6000nm的膜来测定不同操作条件下模型沼气混合物通过膜的通量。在每种情况下,甲烷的出口流量都高于二氧化碳的出口流量,这归因于膜的孔径大小及其过滤较重气体的能力。结果表明,气体的分子量在其渗透速率中也起作用,因为它遵循Knudsen状态。
