You cannot turn on a computer or television, without seeing a story about climate change. Our planet is being choked by man-made emissions, and experts spend countless hours and dollars researching ways to reduce this plague, that we continue to bring upon ourselves. Changes have already been made in many industries, with hybrid vehicles, solar powered homes, and products made of recycled goods becoming ever more popular. But there are still huge questions when it comes to manufacturing and industrial fields. Nuclear power plants, steel companies, waste management facilities, coal mines… all industries that have come under fire in recent years, for producing dangerous emissions. The majority of recommendations to reduce these emissions involve cutting back on production, which could potentially have massive economic repercussions. But here is the thing, there is a simple solution, that has existed for decades. [Read more…]
While the long-term impact of the recent steel tariffs is unknown, we here at GCES recognize that there will be an impact on nearly every company we do business with. With so much confusion, and bias, around this hot topic, we created the below article to help break it down a little.
What is steel?
Carbon steel, which accounts for 90% of all steel production, is an alloy that occurs when iron is combined with carbon. It also contains small quantities of silicon, phosphorus, sulfur and oxygen. The iron that makes steel is the 4th most abundant element, making up about 5% of the earth’s crust. It is removed from crust in the form of an ore; the iron is then extracted from the ore by a process known as smelting. Smelting, simply put, happens when you apply heat to an ore, to extract the base metal. Once the smelted iron is combined with carbon, steel is formed. Although steel is made of predominantly iron, it contains 0.03% and 1,075% (depending on grade) carbon, which alone, iron does not. This addition of carbon improves the physical chemical properties of the iron, making it a desirable metal. On top of the physical properties that make steel so versatile, and desirable, it is also considered to be infinitely recyclable. This means it can be melted down, and reused, as many times as needed, without limit.
Because of its high strength, and relatively low cost, steel is one of the most sought after building materials in the world. Used to make everything from weapons, infrastructure, and buildings, to home appliances and automobiles, the steel industry is expected to reach $1.01 trillion in revenue by 2025. [Read more…]
Cost Effective Pollution Control in a Direct Reduction Plant with a CO2 Desorption Model
In 2005 GCES began their first project in steel production providing a cost effective pollution control solutions for a direct reduction plant with a CO2 desorption model. We were contacted to provide treatment for volatile air pollutants (VOCs) and green-house gases (GHGs). Since that time our thermal oxidizer systems have been implemented to provide a pollution control solution in dozens of steel production facilities across the globe and continue to operate with efficiency and effectiveness.
