摘要

在不同的工艺条件下进行了沼气升级中试的性能测试，以生产用于水介质的富氧空气。聚砜中空纤维对N2O2渗透的选择性允许通过在单道模式下以不同的阶段切割值操作中试装置，产生30-50%范围内的富氧气流和惰性气体(氮气在82-98%之间)。根据气体渗透的简单完美混合模型，讨论了100 Nm3 h−1中型装置对膜面积的要求。

Performance of a hollow fibre membrane unit in oxygen-enriched air production

The performance of a pilot test for biogas upgrading has been tested under different process conditions to produce oxygen-enriched air for aqueous media application. The selectivity of the polysulfone hollow fibres for $N_{2} O_{2}$ permeation allows the production of an oxygen-enriched air stream in the 30–50% range and an inert gas (nitrogen between 82–98%) by operating the pilot unit at different stage-cut values in a single pass mode. Membrane area requirements for a medium size plant of 100 Nm³ h⁻¹ are discussed according to a simple perfect mixing model for gas permeation.
