LCI Study of SCR DeNOx Technology for Cement Industry
LCI study is short for “life cycle inventory study.In the situation of more strict regulation limit of 500 mg NOx /m3 a demonstration project to reduce NOx emissions with clinker production capacity of 2000 t/d in Beijing is supported by the Five-twelfth National Science and Technology Support Program of China Science and Technology Department.A selective catalytic reduction denitration (SCR DeNOx) technology is expected to be applied in this project.LCA models the life cycle of cement manufacturing with SCR DeNOx technology applied as its SCR system.The life cycle is from the coal and raw materials transportation,through the coal and raw meal grinding,to the clinker incineration,and finally the flue gas including NOx to the SCR reactor.The functional unit is 1 ton clinker.Data for cement produced in LNB technology as bench mark is analyzed and the SCR scenarios are to show that the SCR reactor can be established because the additional environmental impact is small due to small consumptions of reducing agent and electricity.SCR technology enable the deNOx efficiency much higher with small environmental impact.
