In this memo, we will examine the environmental challenges of steel and the issue of water transfer in the Persian Gulf and the steel industry. Please be with Artan Press:
Unfortunately, in Iran, unlike most countries in the world, the initial feasibility studies for the construction of steel plants in the water index are not very important, and we see that most steel companies are located in arid and low rainfall areas of Iran. On the other hand, rainfall patterns have been reporting a severe water shortage situation in the country for several years. Therefore, one of the most important industries to which the finger of blame is pointed is the steel industry.
The steel industry is one of the most consumed industries in terms of energy requirements. In the whole world, the amount of water and energy consumption in the steel production sector has always been an acceptable percentage. For example, about 3% of the total electricity produced in Iran is consumed in steel mills, and the country’s electricity distribution company has an annual plan for this consumption.
*** The main important location in the commissioning of steel units
Water transfer from the North Sea and the Persian Gulf was a solution that has been studied for about a decade and has its pros and cons. In the first step, this plan was considered a bit unreasonable, so the logical scenario for this situation was the transfer of steel plants to the northern and southern borders of the country. But this was practically impossible because the cost of construction of these plants and their infrastructure It is not a matter that can be decided for them in the short term. On the other hand, this issue also brought social challenges. Because such a large displacement from the central regions of Iran led to unemployment crises and widespread migration, which made the situation more unfavorable than the current situation.
*** Use of wastewater as steel feed
According to studies conducted by the Artan Press analysis team, about 46% of water consumption in all industries of the country belongs to the steel sector, most of which is provided through the recycling of water consumption. This project alone can solve a large part of environmental problems. But unfortunately, steel water waste is a problem that actually changes the ecosystem of the region and increases the humidity by increasing production volume and increasing humidity in small central cities. It has some.
*** Water-dependent steel industry
Iran’s steel industry is one of the most consumed industries in the field of water. According to the global standard of steel production, to produce each kilogram of steel requires about 8 liters of water, which due to the variety of different technologies in Iranian steel production, this figure can be different in factories. There is an unwritten and, of course, obvious law that says the more up-to-date the technology, the less water is consumed. The amount of water consumption per ton of crude steel production depends on factors such as the type of production process, the variety of volume and quality of products produced and the level of technologies used in each industrial unit.
*** The main causes of water consumption in the steel industry
In the steel industry, water is a very important element. The main water consumption in these factories includes cooling (equipment, furnaces, intermediate products of iron and steel, processed coke, etc.) The source of steam used in the production process or power plants, submerged. Deposition and cleaning of dust and pollutant gases, cleaning of surfaces and removal of oxide shells of solutions of acid washing lines, solvent of aqueous medium for lubrication of oils or water base, dust removal of raw materials are some of the most important uses of water in the steel industry. The value of steel is considered and we must think about it, otherwise one of the strengths and strategic economic bases of Iran will soon be challenged.
*** Benefits of transferring water from the Persian Gulf and open seas to the Central Plateau of Iran
One of the most important benefits of this project will be the independence of steel mills and solving the water supply challenges of these mills. On the other hand, with the entry of water into the central plateau of Iran, the area under cultivation and lands devoid of vegetation will increase due to rising environmental humidity and will practically have a positive effect on the plant ecosystem.
Reducing steel costs will be key with the implementation of this plan. Approximately an average of 2,000 tomans per month is directly spent on the production of water for the production of each kilogram of steel, and if we add hidden costs to this cost, it can double the price. This could severely affect the cost of steel in Iran.
The transfer of water from the Persian Gulf to the central regions has changed the ecosystem of the region and in the long run can have negative effects on the environment. It can be harmful. Therefore, extensive environmental studies should be performed in this field.
*** The initial costs of transferring water from the Persian Gulf and the high seas are borne by steel mills
If the offshore water is transferred, we will need a significant number of desalination plants to make this project cost-effective. As a rule, the initial costs of this sector will be borne by the steel plants. This cost can lead to a sharp rise in the cost of finished products of steelmakers in the first years.
Salt isolated from seawater needs to be programmed, because their storage and accumulation in the environment can change the plant and animal ecosystem over time. With the re-entry of these salts into the water, with the change in the conductivity and salinity of water, aquatic life in the regions will be accompanied by memories.
