Project feasibility

In order to give you the means to decide to carry on with your project, we examine the feasibility each potential improvement represents, from a technical and economic viewpoint. Indeed, all is not feasible or advisable. An unsolvable technical issue or an oversized budget may lead to a project being abandoned or re-qualified.

A feasibility study consists in:

  • Identifying the most efficient technical solution
  • Integrating it into the production process and adapting it to its operational constraints (production flow, process control, maintenance requirements, …)
  • Assessing the implementation budget
  • Assessing potential energy savings as well as future energy performance
  • Identifying financing levers.

Example: production of superheated water from the fumes of an electric arc furnace.

-
The fumes of an arc furnace are one of the main sources of energy loss in an electric steelworks. The challenge is as high as 18 MW!
- Fumes are usually cooled down to 300°C (by cooled ducts and tempering tower) before entering the air treatment system (filtering and cleaning)
- The constraints are as follows:  uneven emissions of fumes, high concentration of hot fumes in abrasive particles, need to limit the recovery system losses, need to design a system which can be isolated from the main stream.

The solution recommended by CMI : an abrasion-resisting exchanger + a bypass sized to withstand 800°C + a water-storage tank + a system to regulate outlet water at 120°C.

Benefit: production of 18 MW superheated water to feed a city network close by.
