TN250 – Gas circulation vessels (normal and high pressures) Private content

In the gas circulation vessels, the connection consists of two coaxial pipes, to enable the continuous and intermittent circulation of gas on the sample (liquid or solid). At the outlet of the vessel, the evolved gases carried by the sweeping gas can be analyzed on line through a gas analyzer. The gas circulation vessels are used with different types of carrier gas (inert, reductive, oxidative) at various pressures, depending on the model of vessel. Using an adapted gas circuit, different ways of experimentation are possible : use a simple carrier gas, or start an experiment with inert gas and switch for active gas in the second part of the experiment, or introduce an active gas in the carrier gas.
