Liquid ammonia is compared with urea as two SCR DeNOx reductants in three aspects of technology, security and economy. lt turns out that the liquid ammonia method and the urea treatment to produce ammonia are both mature,while the urea treatment is more safely. The liquid ammonia has a great advantage in econo-my. The cost of materials occupies 10 to 20 percent of the total cost. And the DeNOx investment of per kW is negative correlated with the size of unit capacity.
