Quality Control Censorship in Pollution for Cement Industry
Course Code: CI 13
Course Overview
In most countries the laws limiting dust and gases emission in the atmosphere are becoming increasingly rigorous. The dust trapped in air and smoke gases normally represents material which can be re-used in the production.
Gas emission is normally defined as the maximum permissible dust content per cubic unit of escaping gas or, in some cases, as the maximum total quantity of dust per hour from a single stack or factory.
This course has been developed to achieve information on the types of pollution in the cement plant from quarries to packing plant.
Familiarize the trainees with the types of Filters, materials transportation and how to control the gases emissions pollution.
The purpose of the course is to upgrade the skills and knowledge of process engineers and operators to control the pollution in the cement plants.
Course Objective
After completing this course participants will:
- Become familiar with the types of pollution in the Cement plant and how to control it.
- Become familiar with the types of filters.
- Become familiar with the raw materials transportation.
- In-depth understanding of the Kiln Gases emission.
- In-depth understanding of the BY-PASS(Alkalis volatiles) and By-pass gas removal system.
- Become familiar with the dust collection system and the function of Pelletizer System.
- In-depth understanding of the role of Efficient maintenance to control pollution.
- Become familiar with the quarries restoration to agricultural Land.
Target Audience
- This course will have a particular focus for people working in the Cement production and process control Engineers, maintenance Engineers, Production and maintenance supervisors, Production and maintenance technicians.
