Innovate Steel, Design Future 20 POSLAB
After starting R&D activities of FINEX® in 1992, it is being scaled up to 2.0 Mt/y
CO2 emissions from FINEX® drastically fell down because POSCO has
developed coal briquetting process and has optimized the FINEX process
by adopting CO2 removal system and pulverized coal injection
A series of technical developments such as heat recovery system, dry dust
collectors and recycling by-products could reduce CO2 emissions furthermore
FINEX® has lots of potential for lowering coal consumption rate and saving energy
as a developing process
