Online Seminar: Sulfur and Chlorine Cycles


Objective:
Improved knowledge about sulphur and chlorine cycles, their process implications, future trends, and technical possibilities to reduce their impact on product quality and emissions
Target Group:
Process engineers, environmental and chemical engineers in the cement industry with experience in process engineering in cement manufacture
Description:
Sulphur, alkalis and chlorides form volatile compounds in the clinker burning process which can affect the production process negatively. As a consequence, it is important to limit these cycles and - if necessary - reduce them. In recent years, these cycles have increased in many kilns due to higher chloride inputs from secondary fuels and raw materials. In some cases, SO2 abatement measures have increased sulphur loads to the kiln. As a consequence, almost all cement kilns are equipped with bypass systems.In this seminar the basics of Cl/SO3 cycles in the cement kiln, the different designs of bypass systems, options for the utilisation of by-pass dust, and best practice in limiting material cycles, will be discussed.

Presentations:
  • Design of bypass systems
  • Theory and behaviour of the Cl-SO3 cycle
  • Modelling of riser design criteria for bypass systems
  • Engineering and reference installations
  • Practical experience with a new bypass
  • Gas treatment and impact on emissions
  • Options for the utilisation of bypass dust
