Simulation and Optimization of a Naphtha Thermal Cracking Pilot Plant

In thermal cracking plants, it is desired to apply an optimal temperature profile along the reactor to minimize the operation cost. In this article a simulator is developed by the use of a mathematical model, which describes the static operation of a naphtha thermal cracking pilot plant. The model is used to predict the steady state profiles of the gas temperature and product yields. Using ...

CFD simulations of steam cracking furnaces using detailed combustion mechanisms

A three-dimensional mathematical model has been developed for the simulation of flow, temperature and concentration fields in the radiation section of industrial scale steam cracking units. The model takes into account turbulence–chemistry interactions through the Eddy Dissipation Concept (EDC) model and makes use of Detailed Reaction Kinetics (DRK), which allows the detailed investigation of t...

Molecular reconstruction of naphtha steam cracking feedstocks based on commercial indices

A new method for feedstock reconstruction of industrially important hydrocarbon fractions is developed using as input the analytically determined ommercial indices such as the average molecular weight, the specific density, theH/C-ratio, the paraffin, isoparaffin, olefins, naphthenes, aromatics PIONA) weight fractions and a set of ASTM boiling points. The method is based on Shannon’s entropy cr...

Evaluation of high-emissivity coatings in steam cracking furnaces using a non-grey gas radiation model

The efficiency of the application of high-emissivity coatings on the furnace walls in steam cracking technology can only be evaluated on the asis of a description of radiative heat transfer distinguishing between the frequency bands. To this end, a non-grey gas radiation model based on he exponential wide band model (EWBM) has been developed and applied in the context of three-dimensional CFD s...
