02Consider how your design fits into bigger systems, like the environment or the economy.

Method & Evidence

AimTo conduct a comprehensive life cycle assessment of the ReNOx technology and compare its environmental performance against traditional NOx treatment methods.

MethodLife Cycle Assessment (LCA)

ProcedureThe study involved quantifying environmental impacts across the entire life cycle of the ReNOx process, including feedstock preparation, adsorption, ammonia recovery, and comparison with selective non-catalytic reduction (SNCR) and selective catalytic reduction (SCR). Various operational conditions and optimization scenarios were evaluated.

ContextIndustrial emissions control, specifically nitrogen oxide (NOx) treatment in flue gas.
