There is a lack of data on the self-ignition behaviour of tetrafluoroethylene (TFE) in industrial sized
equipment. In order to assess the tendency of TFE for
decomposition in large scale vessels, , a facility was
designed and constructed. Tests were
carried out in a cylindrical reactor with a volume of 100 L with initial
pressures of 5 and 10 bar(a). The effect of the reacto
r adjustment (vertical or horizontal) was taken into
account. The current work describes the test set
up and summarizes the experimental results achieved.
Furthermore, this paper reports on a numerical model for
the prediction of the self
-heating of TFE in closed
vessels, which was previously developed for small scale reactors and has been here validated for larger
dimensions with the experiments performed in the new facility.
In the industry there is a lack of data on the Minimum Ignition Temperature of decomposition of tetrafluoroethylene in industrial sized equipment. In order to determine the Minimum Ignition Temperature of Decomposition of tetrafluoroethylene in large scale vessels, a facility was designed and constructed. Tests were carried out in a cylindrical reactor with a volume of 100 dm³ with initial pressures of 5 and 10 bar(a). In agreement with previous experiments with small scale cylindrical vessels, the Minimum Ignition Temperature of Decomposition of tetrafluoroethylene was observed to decrease with the initial pressure. The current paper describes the test setup and summarizes the experimental results achieved. The effect of the reactor adjustment (vertical or horizontal) is discussed. Moreover, simplified equations from the Semenov thermal explosion theory are used to attempt extrapolations of previous and current data on the Minimum Ignition Temperature of Decomposition of tetrafluoroethylene to other initial pressures and vessel volumes.
