Abstract

Ethane-water vapour pyrolysis and the influence of the system parameters on the pyrolysis furnace behaviour were studied using mathematical model describing the reactor constructed from Field's pipes. The parameters under discussion are following: reaction mixture feed rate, inlet pressure, heat transferrer temperature (furnace temperature), addition of overheated water vapour, thickness of coke layer on the reactor walls and radiation heat transfer inside the reactor. All parameters were found to be important. For feed rate, furnace temperature and ethane-water ratio an optimum values set can be evaluated. Coke formation on the reactor walls in case the coke layer is very thin can improve the heat transfer due to surface emissivity increasing. Otherwise the coke layer effect is negative.
