Summary of Technical Renovation of NHD Decarburization Section

AN Lei;PAN Jiajia;Shanxi Jinmei Tianyuan Chemical Co., Ltd.;  
The decarburization section of the ammonia synthesis unit uses the NHD decarburization process. Due to the high CO_2 content in the decarburized gas after decarburization, the H_2 loss is large. To this end, ZUPAC series bidirectional metal folded peak corrugated packing and a new grooved tray liquid distributor are used to reform the decarburization tower. After the revamp, the CO_2 volume fraction in the decarburized gas is reduced from 2.0% to 1.6%, and the annual economic benefit can be increased by about 10 million yuan.
