Simulation and experimental determination of the self ignition of tetrafluoroethylene in a 100-dm³-autoclave

  • The gaseous TFE is a monomer which is used to form PTFE, also known as Teflon®, by a polymerisation process at elevated conditions of temperature and pressure. TFE belongs to the group of chemically instable gases which are able to decompose under specific conditions releasing a huge amount of heat comparable to a gas explosion of flammable gases. Due to several incidents in PTFE – production plants the investigation of the safety related properties of TFE at elevated condition was necessary and resulted in a research project at BAM which is subsidized by the PlasticsEurope association. In a first stage the pressure dependence of the Minimum Ignition Temperature for Decomposition (MITD) was determined in the range of 0.5 MPa - 3 MPa in small autoclaves with volumes of 0.2 dm³ and 3 dm³. These results were used to validate the numerical model and were found to correlate quite well with the simulated values. Nevertheless the applicability had to be confirmed for larger volumes as well.The gaseous TFE is a monomer which is used to form PTFE, also known as Teflon®, by a polymerisation process at elevated conditions of temperature and pressure.

Therefore a heat able 100-dm³-autoclave was constructed and build to determine the MITD in the range of 0.5 MPa to 1.1 MPa.zeige mehrzeige weniger
