Dynamical Model of the Claus Process and its Identification

2007 American Control Conference, 2007
The Claus process is widely used for sulfur recovery from H2S that is contained in natural gas and other fossil fuels. Control of the Claus reaction is difficult because of the nonlinear character and long dead time of the process. A dynamical model of the Claus process suitable for controller design and tuning is developed in this paper. The developed

A new approach for hydrogen production in Claus sulfur recovery process

Journal of Sulfur Chemistry, 2018
ABSTRACTIn this study, the decomposition of hydrogen sulfide and reforming of hydrocarbons were employed for producing hydrogen. Thermolysis of H2S in the platinum-based catalytic reactor led to the production of hydrogen and sulfur. It is observed that the presence of catalyst increased the conversion of H2S decomposition up to 99.6%.

Role of Benzene on Thermal Stage Performance in a Claus Process

53rd AIAA Aerospace Sciences Meeting, 2015
Experimental results are presented on the role of benzene addition to H2S combustion at an equivalence ratio of three with respect to H2S and complete combustion of benzene (i.e. under Claus condition). The results reported here are with addition of 0% and 1% benzene to H2S/O2 flame.

A Simulation of Claus Process Via Aspen Hysys for Sulfur Recovery

Chemical Product and Process Modeling, 2016
Abstract In refineries, due to the environmental pollutions, sulfur content in petroleum need be reduced. The incineration process is used for sulfur recovery system which is not friendly process to the environment and needs high temperature.

Modeling a claus process reaction furnace via a radical kinetic scheme

2004
Abstract 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 ...

Tough assessor or Santa Claus: rationalizing the assessment process

FIE '98. 28th Annual Frontiers in Education Conference. Moving from 'Teacher-Centered' to 'Learner-Centered' Education. Conference Proceedings (Cat. No.98CH36214), 2005
A procedure is described that allows quantitative analysis of assessment results to determine if they are statistically representative of the performance of a student cohort. This procedure provides a method of determining to some degree, whether variations in statistical outcomes of a group are due to the assessment process being unrepresentative or ...

An efficient approach to robust simulation of claus processes in coking plants

2007
Abstract Claus Combustion is a significant process unit in coking plants. Its main purpose is the destruction of gaseous contaminants such as H 2 S combined with the recovery of sulphur. However, since the feed flow contains much more components, it implies a complex gas reaction process, which can be divided into two parts, the furnace and the waste
