| Popis: |
A calculating model is developed, which, depending an the free radical mechanism, enables the calculation of products during the cracking of higher hydrocarbons (naphtha) for olefine production. The validity of the model is proved in comparison with measurements in laboraties and with measurements of a commercial pilot plant. For caupling heat high-temperature reactors into the process of olefine procuction the following possibilities are discussed: heated crack-tubes (with helium or steam) carrier-heat process (high and Iow pressure). The steam erackers are optimized with regard to the residence time and the steam dilution. The originating fraction of methane is led to a steam reforming process for the production of hydrogen. For the different processes detailed energy balances and mass balances are not only given for the cracking but also for the necessary gas separation plants. |
