Concluding remarks
Techno-economic estimation of innovative technologies in chemical engineering

The main messages of this article concern, on the one hand, the evaluation of singular equipment, inherent to the innovation process, and on the other hand, taking into account the type of estimate (preliminary, feasibility, APS and APD) as well as the level of technological maturity (concept, mock-up, pilot, production run). Some recommendations are given below concerning the way in which these results are presented and the scope of the indicators calculated.

• Communication elements

  Evaluating an economic indicator, such as discounted production cost or net present value, has the advantage of aggregating several pieces of economic information, but makes it difficult to compare costs between several teams. It is therefore advisable to provide as many cost breakdowns as possible to ensure traceability of calculation...
