Abstract:
(EN) Provided are a method, and an evaluation device therefor, for deriving an actual separation coefficient that indicates the performance of an actual separation membrane, while maintaining the advantage of simplicity of an evaluation means for an ideal separation coefficient. The present invention is a method for evaluating the quality of a gas separation membrane for separating a mixed gas, the mixed gas including a first component gas and a second component gas that is more difficult to pass through the gas separation membrane than the first component gas, the method including: a step (1) for calculating the permeability of the first component gas when the first component gas is passed through the gas separation membrane as a single gas; a step (2) for calculating the permeability of the second component gas when the second component gas is passed through the gas separation membrane as a single gas; a step (3) for calculating an ideal separation coefficient of the gas separation membrane for the mixed gas, based on the ratio of the calculated permeability of the first component gas to the calculated permeability of the second component gas; and a step (4) for converting the ideal separation coefficient calculated in step (3) to an actual separation coefficient for each of a plurality of gas separation membranes, using the correlation relationship between the ideal separation coefficient derived in advance and the actual separation coefficient indicating the actual separation performance for the mixed gas.
(FR) L'invention concerne un procédé, et un dispositif d'évaluation associé, pour dériver un coefficient de séparation réel qui indique les performances d'une membrane de séparation réelle, tout en conservant l'avantage de simplicité d'un moyen d'évaluation pour un coefficient de séparation idéal. La présente invention concerne un procédé d'évaluation de la qualité d'une membrane de séparation de gaz pour séparer un gaz mixte comprenant un premier gaz de composant et un second gaz de composant qui est plus difficile à passer à travers la membrane de séparation de gaz que le premier gaz de composant. Le procédé comprend : une étape (1) pour calculer la perméabilité du premier gaz de composant lorsque le premier gaz de composant est passé à travers la membrane de séparation de gaz comme gaz unique; une étape (2) pour calculer la perméabilité du second gaz de composant lorsque le second gaz de composant est passé à travers la membrane de séparation de gaz comme gaz unique; une étape (3) pour calculer un coefficient de séparation idéal de la membrane de séparation de gaz pour le gaz mélangé, sur la base du rapport de la perméabilité calculée du premier gaz de composant à la perméabilité calculée du second gaz de composant; et une étape (4) pour convertir le coefficient de séparation idéal calculé à l'étape (3) en un coefficient de séparation réel pour chacune d'une pluralité de membranes de séparation de gaz, à l'aide de la relation de corrélation entre le coefficient de séparation idéal dérivé à l'avance et le coefficient de séparation réel indiquant la performance de séparation réelle pour le gaz mélangé.
(JA) 理想分離係数の評価手段の簡便さという長所を維持して、現実の分離膜の性能を示している実分離係数を求める方法およびその評価装置を提供する。 本発明は、混合ガスを分離するガス分離膜の品質評価方法であって、混合ガスが第1成分ガスおよび第1成分ガスよりも前記ガス分離膜を透過しにくい第2成分ガスを含み、第1成分ガスを単ガスとして前記ガス分離膜に透過させるときの第1成分ガスの透過度を算出する工程(1)と、第2成分ガスを単ガスとして前記ガス分離膜に透過させるときの第2成分ガスの透過度を算出する工程(2)と、算出された前記第2成分ガスの透過度に対する前記第1成分ガスの透過度の比から前記混合ガスに対する前記ガス分離膜の理想分離係数を算出する工程(3)と、複数のガス分離膜のそれぞれに対して、予め求めておいた理想分離係数と実際の混合ガスに対する分離性能を表す実分離係数との相関関係を利用して、工程(3)によって算出された理想分離係数を実分離係数に換算する工程(4)とを含む。
