Presentation you don't want to miss at LP2016: Gas-Phase Detonations in Pipes

[LP2016 preview] Gas-Phase Detonations in Pipes: The 8 Possible Different Pressure Scenarios and their Static Equivalent PressuresResults of a thorough experimental work at BASF


The unexpected large number of high quality submitted contributions to the LP2016 event, allowed for just one Keynote lecture (i.e. a lecture of 60 minutes). For very good reasons it is this one! Expect a very technical presentation which every specialist in this area will certainly enjoy. Due to the amount of information included, the scientific committee of the event allowed the author to support his lecture with not one, but two full peer-reviewed papers. Both papers will be published in time for the LP2016 event and will be freely distributed to all participants. This is also an excellent example of world class experimental safety research that is financed and performed solely by an industry, in this case BASF, and then publically shared with the safety community

Further infos on the presentation:

  •  Title: “Gas-Phase Detonations in Pipes: the 8 Possible Different Pressure Scenarios and their Static Equivalent Pressures Determined by the Pipe Wall Deformation Method”
  • Speaker: Dr. Schildberg, BASF SE
  • Summary:

In this work for the first time ever a systematic classification of the different detonative pressure scenarios in pipes is established. To do so, it is proposed to define two different pipe types and to distinguish between 8 different detonative pressure scenarios. In a next step the pipe wall deformation method is proposed which allows to assign to each of the 8 detonative, highly dynamic pressure scenarios an equivalent static pressure which can then be used in the formulae of by the established pressure vessel guidelines, which can only cope with static loads, to determine the desired detonation pressure proof pipe design. Based on the large number of experiments done so far, a proposal is presented which allows to predict in good quantitative approximation all short pipe scenarios on the basis of two long pipe scenarios, which substantially reduces the experimental effort. The expected variation of the static equivalent pressures with variation of initial temperature, initial pressure and the mixture composition is discussed

Key take-home message of the lecture: The existing pressure vessel design guidelines must be improved to encompass the design rules for detonation pressure proof pipe design.
