Determination of Hydrogen-propane Condensation Curve

Stricter environmental legislations make necessary or even profitable the utilization of gases that are by-products from different production processes and which have been wasted so far. To design the most suitable utilization technology for these gases a detailed knowledge of their properties is required. The parameters of vapour-liquid phase change are crucial for fuel handling. The physical and chemical properties of most commonly used gases are well known but the broad variety of gases produced during different industrial processes has not been investigated yet. The simple, fast and precise method of determination of their condensation curve is very useful. The determination of condensation curve for a gas composed mainly of hydrogen and propane has been described. The measurement method and testing equipment is universal and can be used for various compositions of gases and is also very suitable for gases containing a significant amount of hydrogen.
