摘要
二氧化碳的净化难点在于脱除有害物质氮氧化NOX.研究了尿素水溶液还原法去除氮的效果氮氧化物浓度可从650×10-6降至3×10-6以下,去除率达99%以上.
The nitrogen oxides in the waste gases are harmful substances and must be removed.It took two years in experiments on the new process for removing the nitrogen oxides by means of reducing method of urea water solution.At last the removing results are so desirable that the concentration of nitrogen oxides can be decreased from 650ppm to below 3ppm,the removal rate is over 99%.
