In-flow measurement of the composition of a binary gas mixture

Abstract The performance of many cryocoolers that utilize the Joule-Thomson effect can be improved by using a gas-mixture as working fluid. This paper presents measurement setup to characterize sorption compressor operating with binary mixture. composition mixture delivered is determined in-flow correlating outputs Coriolis flow meter and thermal mass-flow meter. Based on this method, was measured continuously an error ±0.02. Multiple cycles three different mixtures ethane nitrogen same were measured, allowing for observation dynamic desorption behavior
