The metallurgical industry is a strategic sector in which a large number of companies and people work.
In the course of their work, the enterprises themselves, the infrastructure, and the mining itself generates waste that not only has a negative impact on the environment but contributes to the increase in the cost of metal due to the costs of its disposal.

As well, coking coal is a strategic raw material. Its value has a significant impact on the final price of the finished product.
In the metallurgical sector, the gasification technology is primarily focused on the recycling of hydrocarbon-containing waste with the possibility of saving coke. In the process of UNIVASTUM's gasification process, a large amount of heat reducing gases (CO, H₂) are formed. And these gases can be applied in the blast furnace, thus saving scarce coke. In addition, the carbon dioxide (CO₂) obtained during gasification, interacting with hot carbon (coke) forms additional CO, that is, it participates in the metal smelting process.
Thus, the waste disposal using UNIVASTUM's technology actually eliminates the release of CO₂ into the atmosphere. In addition to various wastes in the gasification complex for the production of hot reducing gases, less valuable and cheaper types of coal (including brown) and peat can be used.

The Solution
UNIVASTUM has developed a number of unique and effective solutions for the gasification of waste with the generation of electricity, heat and cooling and as a result energy costs are reduced.
The main technological parameters of the produced gas, depending on the use of the UNIVASTUM complex, are with the use of OXYGEN and without supply of OXYGEN.
The temperature of the produced gas at the outlet is 200 °C, with a pressure of 1 bar. Productivity in both cases is a little over 6800 m³/h. Moreover, in the case of the base case, i.e. without oxygen supply – the total amount of CO and H₂ reducing gases supplied to the blast furnace will be 1 t/h or 8000 t/year.
In the second case, with the use of oxygen, the productivity of reducing gases will increase by more than 2 times and will be 2.4 t/h or 19 150 t/year.
This performance is achieved by changing the ratio of components in the composition of the product gas, as well as by reducing the nitrogen content as a result of oxygen supply.
The principle of calculating coke savings is based on comparing the amount of coke and reducing gases necessary to produce iron for the indicated reactions. To recover 1 kg of 3-valent iron oxide, about 250 g of coke or 562 g of CO and H₂reducing gases will be required.

In accordance with this, the total amount of iron ore from
Fe2O3 reduced with CO and hydrogen without using oxygen in UNIVASTUM will be 3000 kg/h, and in case of using oxygen 6500 kg/h.

Thus, the saving of coke for the recovery of the same amount of iron ore in the first case will be 750 kg/h or 6 000 t/g, and in the second case, the savings will be 1600 kg/h or 12 800 t/year.
