摘要

Project is sensitive to recovery boiler limiting assumptions 5.22% increase in production for solids limit with 15%IRR 9.6% increase for steam limit with 34%IRR Using the lignin product as lime kiln fuel was shown to be more profitable than pelletizing the lignin Higher direct costs associated with pellet plant operation Higher CAPEX with pellet plant
