However, profiles of temperature and concentration, along the length of reactor are matching. Model predicted results and an industrial data are matching in terms of concentrations of species but have some deviation in terms of temperature and pressures predictions. A detailed simulation study is carried out and the model predictions are compared with the industrial data and the data reported in the literature. A detailed free-radical mechanism for the reaction kinetics coupled with material, energy and momentum balances of the reactant-product flow along the reactor is considered.
An industrial reactor unit using ethane as a feedstock is simulated for the molecular reaction scheme with 8 components and 5 reactions. Present work focuses on the simulation of ethylene production plant. Thus any improvement in the process of ethylene production may enhance the industrial economic output. Ethylene is produced in the largest volume among the important base petrochemicals that forms the building blocks of the petrochemical industry. A mixture of inert steam and hydrocarbon feed stocks are entered into coiled tubular reactors with high temperatures and short residence times. The olefins are widely produced using thermal cracking of light hydrocarbons such as ethane, propane, n-butane and their mixtures.
