Modeling a Claus Process reaction furnace via a radical kinetic scheme

摘要

In view of reducing the impact of gaseous pollutants into atmosphere, the regulations governing the emissions of Sulphur from Claus plants have become increasingly strict. Despite this fact, many process calculations routinely adopt empirical or semi-theoretical thermodynamics models based on equilibrium to estimate product distributions from the front end of sulphur recovery plants. More over from a design perspective the furnace is a critical equipment of the sulphur recovery unit, being also the source of key compounds that ultimately dictate the operation and efficiency of the plant. The CMIC Department of "Politecnico di Milano" and Technip-Coflexip ( a leader on Sulphur recovery processes) set up a joint project with the main objective of creating a significant phenomenological furnace model based on non equilibrium approach aimed to a detailed radical kinetic scheme.
