Better Life with MgO

Objectives

The main objective is to demonstrate that a new dry desulfurization technology utilizing magnesium oxide (MgO) as a sulfur oxide (SO_x) pollutant sorbent is a Positive Net Environmental Impact Solution for magnesia industries, especially in those areas where limited water availability renders wet technologies inapplicable.

The project ventures a) to prove that the SO₂ emission limit value (ELV) of 1.500 mg/Nm³ with an overall SO₂ reduction efficiency of at least 60% can be accomplished with a dry technology based on MgO and b) to update the Cement Lime and Magnesia Best Reference Document (CLM BREF) accordingly.

Other objectives include:

• To utilize and/or upgrade at least 90% of the generated waste (a dry powder consisting of magnesium oxide, magnesium sulfite and magnesium sulfate, i.e. MgO/MgSO₃/MgSO₄) to be used in fertilizer and construction applications
• To demonstrate that a reduced energy consumption by at least 40% is possible compared with wet desulfurization technologies
• To demonstrate that a reduced water consumption by at least 80% is possible compared with wet desulfurization technologies
• To replicate the results to Magnesia sector and transfer them to other relevant European energy intensive combustion industries
