The interest in environment management

The interest in environment management, based on the application of scientific principles and engineering in order to improve and secure the labour and the workand surrounding environment, in order to maintain human health in particular and the health of the rest of the natural components of society in general, for the purpose of treating effects resulting from human activity that makes a change in the natural environment either through the issuance of emissions or pollutants effect environment nature.

This is what was adopted by the company of programs concerned with the environment through, searching for projects, systems and programs that simulate these problems, and attention mainly on the development of existing facilities and the search for new and alternative technologies for environment protection and for the proper management of natural resources. As well as search for an integrated technological solutions for resource management and waste recycling and diverse sources away "from environment degradation and dissemination of all forms of pollution.

Aware ,,, of the importance of the protection of the production elements (product, machine, raw materials, and the environment) of industrial pollutants taken into account when started to build the iron and steel industry the effects associated with the production process and environmental factors and to reduce the emissions from this activity so that we can limit and control these effects of plants and facilities for the company's many environmental  systems and develop a mechanism in how to deal with it, but these systems require a special and serious attention to the operation and maintenance, training and development to keep pace with scientific development in this area in addition to the development sought by the company for its plants and facilities in  according to the latest technology.

First: company pollution control systems and equipment

• control systems types and components

    Taking into account when   started to build this  large industrial compound to design its plants and facilities  In line with international standards in the field of pollution control and protection of the environment by providing plants  And many of the company's facilities for the control of emissions through   emissions and pollutants, whether (gaseous, solid, liquid) and so as to maintain the overall environment and the control of these pollutants the importance of environment Systems is as following: -

  • control of emissions and measurements according to international standards.
  • protection of workers and the work environment from pollution.
  • protection of the environment and the surrounding from pollution.
  • protect the humans from the dangers of emissions.
  • energy conservations and improvement of product quality

the following  systems are attached to the company's plants and facilities as follows: -

 1. waste gases systems

These are instruments for control of emissions which take samples of the air passing through the burning chimneys and analysed and shown graphically on the control panels to determine the emission rate

Components: air pumps to withdraw the burning air and analysis and rates display unit ​​to show light and sound alert signals In addition to the chimneys.

Their places: The following sites (electricity and desalination plant, dri plant, long rolling mills, flat rolling mills, lime plant).


Purpose: These systems monitor the following emissions (nitrogen oxides, sulphur oxides, smoke)

                     (chimneys)                     (rates display at ​​control rooms)            (Pump to withdraw dust)  

2. Dust systems

these equipment to deal with dust, through which dust is withdrawn by suction fans from belts and equipment and collected dust is pumped into the vessels.

 Types: * suction and collection dust inside the vessel directly * suctionand deposition ofdust by water

Components: the components of these systems vary depending on the location in terms of size, power and Generally consist Of suction fans vessels and filters)

Their places: The following sites (steel mills, dri plant, lime plant).

Purpose: These systems process the dust by collection

(dust collection and pelletizing systems)               (dust collection systems)                (Dust by water systems)

3. deposition systems:

It is an equipment to deal with the outstanding solids in direct cooling water through the accumulated sedimentation basins in production sites before being sent to the Central Station, the plankton is the mud and scales, oils and greases associated with the production processes (accumulate and formed of mud and scale)

 

Components: sedimentation basins, scrape oil machines, pumps, drainage channels for water collection

places: steel mills and dri plants, rolling mills "long and flat mills" central water station

Purpose: deposition and collection of plankton and scrape and oils collection


         (sedimentation basins)                           (pumps chamber)                      (oils scraping machine)                    

 

4. Early warning systems:

It is a equipment to monitor emissions of carbon monoxide in the region and warn about it

Components: gas Sensors, light and sound alert signals at "control rooms and the site"

places: direct reduction plants

Purpose: the detection and early warning about carbon monoxide "Co" leaks

          (internal alarm signals)                            (light and sound alarms)                               (Gas Sensors)                                    

5. rainwater pumping stations

They are stations to control rain water including but not allowing plankton to accompany the water when discharged, where the water accumulate through water drainage across the floor of channels until it reaches a certain level, then the pumps start drainage process, and if the presence of plankton (wood, leaves, dust, scale, oils, greases, ..) is scrubbed from the basins by the crane attached to the station to the designated area.

Components: submersible Pumps, sedimentation and water collection basins,  cranes

Their places: The company has (6)stations distributed at distances of several rooms attached to the discharge station

 Purpose: to get rid of rainwater and other drainage water through the attached drain rooms.

(cranes to remove plankton)            (sedimentation and water collection basins)           (Submersible pumps)
