Engineering and Construction

Design Project
Project topics will be selected from a suggested listing on an approved topic of interest to the student. The final document ought to be around 20 – 25 pages including text, drawings, photographs, tables and diagrams. The project will develop the students’ ability to design real world industrial devices suitable for manufacturing and installation
appropriate format including title page, contents page, introduction, some appropriate headings, design chapter, conclusions, references, all calculations need to be hand written and scanned.

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.

Local Emission Standards (maximum allowed emissions)

Co – 0.04 g/ m3

NOx – 0.05 g/ m3

SOx – 0.03 g/ m3

Particles – 0.02 g/ m3

Others – 0.05 g/ m3
