Abstract Gas filled membrane absorption process (GFMA), or hollow fiber gas membranes process (HFGM) can replace two units operations (absorption and stripping) in a unique stage based on membrane contactors. But its application at industrial scale is still emerging: only cases of ammonia removal and concentration have been reported. This advantage has not been enough to scale it up to pilot prototypes for different applications, probably because (i) experimental tests have been carried out with modules that do not exist at industrial scale, and the selection of the mass transfer correlation for different purposes lacks rigour with respect to the original conditions of the correlation, and (ii) industrial modules configurations focused only on gas absorption applications. The first problem limits the experimental results for scientific purposes only, making these results unreproducible for the design of a pilot or industrial plant. Furthermore, the selection of experimental modules has generally been established to validate an application, limiting the search for an optimal performance. The high quantity of mass transfer correlation also complicates the selection to design or scaling-up purposes. This work includes then a review of the first problem, by conducting an evaluation of mass transfer performance of different membranes modules configuration proposed in literature. The aim is to identify the best experimental configurations for a GFMA process that will lead a further scaling up. This evaluation was carried out using a phenomenological model of GFMA process developed for an application of cyanide recovery in the gold mining industry. The best performance was achieved in membranes modules having cross flow with center baffle and fully baffled.

GFMA 过程中传质相关性的性能评估：对设计观点的回顾

摘要 充气膜吸收工艺 (GFMA) 或中空纤维气体膜工艺 (HFGM) 可以在基于膜接触器的独特阶段中替代两个单元操作（吸收和汽提）。但其在工业规模上的应用仍在不断涌现：仅报道了除氨和浓缩的案例。这一优势还不足以将其扩大到不同应用的试点原型，可能是因为 (i) 实验测试已经使用工业规模不存在的模块进行，并且缺乏针对不同目的的传质相关性的选择相关性的原始条件的严格性，以及 (ii) 工业模块配置仅专注于气体吸收应用。第一个问题限制了仅用于科学目的的实验结果，使这些结果无法用于中试或工业工厂的设计。此外，通常已经建立了实验模块的选择来验证应用程序，从而限制了对最佳性能的搜索。大量的传质相关性也使设计或放大目的的选择复杂化。这项工作包括对第一个问题的回顾，通过对文献中提出的不同膜组件配置的传质性能进行评估。目的是确定 GFMA 工艺的最佳实验配置，这将导致进一步扩大规模。该评估是使用为氰化物回收在金矿行业中的应用而开发的 GFMA 过程的现象学模型进行的。在具有中心挡板和完全挡板的横流的膜组件中实现了最佳性能。
