Non-sooting counterflow diffusion flames have been studied both computationally and experimentally, using either JP-8, or a six-component JP-8 surrogate mixture, or its individual components. The computational study employs a counterflow diffusion flame model, the solution of which is coupled with arc length continuation to examine a wide variety of inlet(More)
This paper reports the equation-based SPYRO model, including its optimisation features. A flexible equation-based SPYRO model and solver for the simulation of the steam cracking process was the basis for the creation of a program with optimisation capabilities. This is now feasible because of the nowadays available computer power. The optimiser uses a(More)
This paper presents the approach and the results of a kinetic generator in the area of hydrocarbon pyrolysis mechanisms. Radical formation and successive radical decomposition are taken into account. Care is paid to the description of molecule identification procedure and to its homomorphism which enables unique and no ambiguous reactions. New results(More)

The modeling of thermal reaction furnaces of Sulfur Recovery Units (SRUs) is a rather complex problem since it involves different modeling scales such as the kinetic/molecular scale, the reactor scale, and the chemical process scale. This work introduces the multi-scale modeling approach to characterize the kinetic and reaction engineering scales for the(More)
Multi-scale process modeling is very appealing methodology for process optimization since it highlights certain issues that remain unexplored with conventional methodologies and debottlenecks certain potentialities that remain unexploited in chemical plants. In this work, a kinetic model with 2400 reactions and 140 species is implemented in a proper reactor(More)
