Abstract
【解決手段】上記目的は、超化学量論比のプロセス空気とアンモニアの触媒ガス相酸化によりNOとO2を含むガス混合物を得る工程、NO及びO2を含むガス混合物を冷却/濃縮し、及びNOをO2により更にNO2/N2O4へと酸化し、硝酸を含む水溶液及びNO2/N2O4を含むガス流を得る工程、及び、NO2/N2O4を含むガス流からNO2/N2O4を、吸着体中の工程水に向流吸着させ、濃度が50〜77.8質量%の範囲である硝酸及びNOXを含む吸着体排ガスを得る工程により濃度が50〜77.8質量%の範囲である硝酸を製造する方法であって、硝酸の水分含量が50〜77.8質量%の範囲に調整され、及び吸着体排ガスのNOX含有量が20〜500ppmに調整され、その調整は触媒ガス相酸化に導入されるプロセス空気の水分含量を連続的に測定し、及びこれに依存して、吸着体に導入される工程水量を調整することにより行われることを特徴とする方法により達成される。
【選択図】図1
Description
吸着体に供給された工程水の量は、製品中の水分含量により増加した硝酸製品の合計量に対応し、硝酸形成のために要求される水、及び、アンモニアの触媒燃焼反応の水及びプロセス空気の量により導入される湿気からの吸着体特異的ファクターにより増加した吸着体排ガス中のNOXの量が引き算される。
