GAS SEPARATION DEVICE, MEMBRANE REACTOR AND HYDROGEN GENERATION UNIT

摘要

FIELD: power industry.;SUBSTANCE: gas separation device that separates carbon dioxide and water vapour from the first mixture of gases, which contains the specified main gas component, carbon dioxide and water vapour, the energy efficiency of which is increased. The gas separation device is made so that it can include the first isolating diaphragm and the second isolating diaphragm, which are made from different materials. When the first mixture of gases is supplied at the temperature of 100°C or higher, the first isolating diaphragm isolates the second mixture of gases, which contains carbon dioxide and water vapour, which penetrates through the first isolating diaphragm by provision of selective penetration of carbon dioxide and water vapour. When the second mixture of gases is supplied, the second isolating diaphragm isolates water vapour that penetrates through the second isolating diaphragm by provision of selective penetration of water vapour.;EFFECT: invention allows increasing use efficiency of energy in a gas separation device.;14 cl, 29 dwg
