l摘要双加压法生产稀硝酸工艺是当今世界最为先进的稀硝酸生产工艺。双加压法生产硝酸的氧化压力适中，吨酸铂耗少，吸收压力高，对氮的氧化物吸收有利，产酸浓度高，氨耗低，酸尾排放的NOx含量低。双加压法的这些优点，使其占据了主导地位。关键词：双加压法工艺流程稀硝酸Abstractthedevelopmentofmedium-pressuremethodforhighpressurelawanddual-pressure,dual-pressureproductionofdilutenitricacidprocessisthemostadvancedintheworldtoday,dilutenitricacidproductionprocess.Comparedwithothermethods,dual-pressureproductionofnitricacidoxidationpressureismoderate,tonsofacidplatinumconsumption,highpressureabsorption,absorptionofnitrogenoxidesfavorablehighconcentrationsofacidproduction,ammoniaconsumptionislow,acidtailemissionsofNOxcontentislow.Theseadvantagesofthedual-pressureprocess,ithasdominatedintheproductionofnitricacid.Keywords:dual-pressureprocess;process;dilutenitricacid目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc354666527"摘要PAGEREF_Toc354666527\h1HYPERLINK\l"_Toc354666528"AbstractPAGEREF_Toc354666528\h2HYPERLINK\l"_Toc354666529"目录PAGEREF_Toc354666529\h1HYPERLINK\l"_Toc354666530"第1章硝酸生产发展简史PAGEREF_Toc354666530\h1HYPERLINK\l"_Toc354666531"1.1硝酸的工业应用和生产概况PAGEREF_Toc354666531\h1HYPERLINK\l"_Toc354666532"1.2常用的硝酸生产工艺PAGEREF_Toc354666532\h1HYPERLINK\l"_Toc354666533"1.3硝酸生产工艺之间的比较PAGEREF_Toc354666533\h2HYPERLINK\l"_Toc354666534"1.4双加压法稀硝酸在我国的生产现状PAGEREF_Toc354666534\h4HYPERLINK\l"_Toc354666535"第2章双加压法硝酸工艺流程简介PAGEREF_Toc354666535\h6HYPERLINK\l"_Toc354666536"2.1主要经济指标和参数控制PAGEREF_Toc354666536\h6HYPERLINK\l"_Toc354666537"2.2生产原料的选取PAGEREF_Toc354666537\h7HYPERLINK\l"_Toc354666538"2.2.1工业上对液氨的要求：PAGEREF_Toc354666538\h7HYPERLINK\l"_Toc354666539"2.2.2对空气的要求：PAGEREF_Toc354666539\h7HYPERLINK\l"_Toc354666540"2.2.3对水的要求：PAGEREF_Toc354666540\h8HYPERLINK\l"_Toc354666541"2.2.4氨催化剂PAGEREF_Toc354666541\h8HYPERLINK\l"_Toc354666542"2.2.5润滑油（L-TSA46防锈汽轮机油）PAGEREF_Toc354666542\h9HYPERLINK\l"_Toc354666543"第3章流程分析双加压法硝酸工艺PAGEREF_Toc354666543\h12HYPERLINK\l"_Toc354666544"3.1主要反应方程式PAGEREF_Toc354666544\h12HYPERLINK\l"_Toc354666545"3.2氨氧化反应及影响因素
