TTI Preparing to start a New Chapter
 Main objectives of the 2015 project:
 New reactor design, worlds most advanced?
Most Efficient Reactor
• Capacity Increase + 15%
• Process control, prepare for Hot Charging
from Hydrogen reduction.
• Working conditions, Environment, and
Safety improvements
 Reactor start up December 2015
 All objectives met within good margins
 2016 Successful trials on continous lab-scale
H2-reduction tests close to being concluded.
Challenges :
Replacing a fully functioning production plant with another technology:
 Mostly finacial and regulatory:
• Market(products and factor inputs (el))
• Availabilty and level of govermental support
• Availability and level of risk capital.
• Emission costs.(CO2)
