Project title:
Implementation of top-pressure recovery turbine at Alchevsk Iron and Steel Works
Facility amount:
1 unit
CAPEX:
$ 45 million
Supplier:
 Mitsui engineering & shipbuilding Co. Ltd.
Project location:
Ukraine, Lugansk oblast, Alchevsk city

Project summary

The project envisages the reduction of energy consumption at PJSC “AISW” produced at electricity grid on the basis of fossil fuel due to the implementation of the modern energy saving equipment on CCGT basis.


Technical aspects of the project

The project includes CCGT building with fixed capacity of 200 MW.

The project of CCGT building for blast furnace #2 at PJSC “AISW” includes gas turbine, generator, reducer, inlet and outlet запірні or emergency valves, and also the system of blast furnace gas treatment. The electricity, produced at CCGT, is planned to be used for own needs of steel mill.

Project efficiency

The implementation of CCGT at PJSC “AISW” will lead to the reversion of some energy portion, wasted for compressed air production at blast furnaces in the way of using surplus pressure of blast furnace gases for energy production. It’ll increase the efficiency of primordial energy usage, and also will save money, wasted for blast furnace blowing production.

The project aims to reduce expenses for compressed air production at OJSC “AISW” or for electricity purchasing.

The CCGT implementation at blast furnace #2 at PJSC “AISW” will lead to non-fuel compressed air production in the volume of 123,2 mio.kW-g/year.

The average efficiency for the facility of energy production is equal to 80%.

Project socio-economic consequences

The project implementation will have the raw of socio-economic consequences for the mill and region, such as:

  • reduction of the production cost of the final production, increase of its competitiveness, and also the realization of similar products stimulation at the other steel enterprises;
  • economic condition improvement in the region due to the increase of money deduction to the budgets of all levels, including the social needs, preventing of the work places amount reduction and assistance to working conditions improvement;
  • renewal of the economic activity due to the attraction of native engineers, contractors for project implementation;
  • improvement of the general resource efficiency and also the improvement of PJSC “AISW” position at the production market.

Similar projects have been initiated at PJSC “Dneprovsky Integrated Iron and Steel Works named after Dzershinsky”, PJSC “Yenakievo Iron and Steel Works”, PJSC “Azovstal Iron and Steel Works”.
