Weighting 35%
The production of portlandcemem is a four-step process: (1) acquisition of raw materials, (2)
preparation of raw materials for pyroprocessing, (3) pyroprocessing of raw materials to form
portland cement clinker, (4) grinding of the clinker to portland cement. The pyroprocessing
system is generally described as containing three steps or zones: (1) drying or preheating, (2)
calcining, and (3) sintering. A rotary kiln is the common element in all perprocessing systems.
The main parameters of the kiln exhaust gas:
Temperature of exhaust gas stream- 250°C
Flow rate – 190,000 m3/h
Concentration of particles: 3.6 g/ m3
NOx: 0.03 g/ m3
Particle size distribution: 0.5-14um
You are asked to design and construct a suitable air pollution control technology to prevent the
emission of particulate pollutant to the atmosphere. The final document must include:
1. Introduction (description of the main process).
2. Literature review ( description of different air pollution control technologies, their
advantages and disadvantages and analysis of the possibility of utilisation for the
particular process).
3. Main chapter ( design and costing of the air pollution control technology: calculations,
diagrams, sketches, etc).
4. Conclusions and recommendations.
5. List of references.
6. Poster (A4 paper size), outlining the main findings of the design, must be attached to the
final document.
