Stand-alone CO2 capture and CO2 capture combined with methanol production from Tata Steel IJmuiden’s blast furnace gas

Bergsma, M (2016) Stand-alone CO2 capture and CO2 capture combined with methanol production from Tata Steel IJmuiden’s blast furnace gas.

Abstract:The iron and steel industry accounted for approximately 6.7% of total global CO2 emissions in 2014. Tata Steel IJmuiden produced 12.6 MMT of CO2 in the year 2014-2015. Tata Steel IJmuiden operates two blast furnaces, which together generated 34.21% of these total CO2 emissions in 2014-2015. The blast furnace gas, a main by product from the blast furnaces, is a fuel gas that can be combusted for energy production. In the current situation a large part of this gas is exported to the nearby Nuon power plant which generates electricity from it. The EU emission trading system (EU ETS) is a cornerstone of the EU’s policy to combat climate change. The trading system works on the ‘cap and trade’ principle. The cap is set on the total amount of certain greenhouse gases that can be emitted by installations covered by the system. The cap is reduced over time so that total emissions fall, making it more expensive to emit greenhouse gases. After every year Tata Steel must own enough allowances to cover all its emissions, or it will incur a penalty. The price of emitting CO2 is likely to rise in the coming years. Research objective In order to lower CO2 emissions, Tata Steel IJmuiden is investigating techniques that will capture CO2 from their work-arising-gases. The blast furnaces are the largest CO2 emitters on site. Therefore my research purely focuses on blast furnace gas that is currently being used to produce electricity. The main objective of this research is to investigate whether the blast furnace gas can be used to produce methanol in an economically attractive way while reducing CO2 emissions. Two situations will be analyzed.  The first scenario is stand-alone CO2 capture from the blast furnace gas. The remaining gas is used to produce electricity.  The second scenario will focus on producing methanol from blast furnace gas. The CO2 will be removed from the blast furnace gas and the remaining gas will be used to produce methanol. Both scenarios will be analyzed by performing techno-economic analyses. The main research question is: Is it economically feasible to solely capture CO2, or combine CO2 capture and production of methanol from Tata Steel IJmuiden’s blast furnace gas using mature technologies?
