Abstract

Modeling of methane combustion in air carried out in environment modeling of chemical processes software package Process Informatics Model (PrIMe). To investigate the methane combustion in air in a program PrIMe was chosen mechanism GRI 3.0, which describes burning of methane and other hydrocarbons (acetylene, propane). Kinetic mechanism GRI 3.0 describe the reactions taking place at the molecular level, which deals with the order in which communications are broken or formed. The mechanism chosen from base of the PrIMe program consists of the 309th reaction and 53 reagents, and also for modeling of burning Plug Flow Reactor (PFR), the reactor of ideal replacement, has been chosen stoichiometric mix of burning of methane in air. Modeling methane inlet combustion air at a low pressure can be seen that almost no chemical reactions occur, but with increasing temperature the reaction proceed faster also can be seen that the fuel in the pyrolysis of nitrogen containing radicals leads to the formation of nitrogen oxides NOx.
