Technoeconomic analysis combines process modeling and engineering design with economic evaluation…,
… to provide both quantitative and qualitatively understanding of the
impacts that technology and research breakthroughs have on the
financial viability of a conversion strategy

Technoeconomic Analysis
Technoeconomic analysis can be used at different levels of rigor at all pre-commercial stages

Technoeconomic analysis is a tool used to determine life cycle costs of a project
Life cycle
costs are the
total one time
and recurring
costs that
occur over the
life of a
project
Technoeconomic
analysis provides
the basis for life
cycle costs inside
the plant gate
