| Description
| - By transport of some dangerous gases and liquids in chemical engineering is very important to detect a possible leak along the pipeline. The leak can be detected by a system which consists of special permeable detection pipeline placed very close to the main transport pipeline. In defined time cycles, the air column in the detection pipeline is transported to the transported substance sensitive sensor. System sensitivity depends on the detection pipeline permittivity. In this paper, the diffusion properties of silicon (polymethylsiloxane) pipeline were analyzed in laboratory experiment. The silicone pipeline membrane has been placed in the atmosphere with known concentration of mixture of hydrocarbons. Sorption and non-linear diffusion coefficients of the membrane were estimated. Finally, a FEM - model of the perforated detection pipeline was made, the hydrocarbon penetration was measured in an experiment and both data was compared.

- Při transportu některých nebezpečných plynů a tekutin v chemickém průmyslu je velmi důležité detekovat případné úniky podél potrubí. Únik může být detekován systémem tvořeným detekčním potrubím, které je umístěno velmi blízko hlavnímu transportnímu potrubí. V definovaných časových cyklech je transportován vzduchový sloupec v detekčním potrubí k citlivému senzoru. Citlivost systému závisí na permitivitě detekčního potrubí. V tomto příspěvku byly analyzovány difuzní vlastnosti silikonového potrubí (polymethylsiloxane) v laboratorním experimentu. Silikonová membrána potrubí byla umístěna v atmosféře se známou koncentrací směsi uhlovodíků. Byla odhadnuta sorpce a nelineární difuzní koeficient memrány. Nakonec byl vytvořen model perforovaného detekčního potrubí, byla experimentálně změřena penetrace uhlovodíků a oba způsoby byly porovnány. (cs)
