硝酸生产工艺 硝酸生产过程中的工艺控制 硝酸 (HNO3) 又名硝镪水或氨氮水,用于生产作为肥料原料的硝酸铵。硝酸也是生产己二酸和对苯二甲酸的关键成分。其他应用包括炸药、溶浸采矿和不锈钢酸洗。根据所需的最终浓度不同,硝酸生产流程可能包含一种或两种工艺。 硝酸通常由氨经高温催化氧化制得。此过程包括三个主要步骤:氨氧化、一氧化氮氧化和吸收。 最常见的催化剂由大约 90% 的铂和 10% 的铑(质量百分比)组成。 催化剂在金属丝网中成形并插入转化器中。放热反应继续进行,生成约 93-98% 的一氧化氮。随后,一氧化氮会冷却至特定温度并达到规定的压力。接下来的反应高度依赖于温度和压力。 冷却后,二氧化氮/四氧化氮混合物将进入吸收塔。吸收后,酸浓度通常在 55-65%(质量百分比)之间。 维萨拉 K-PATENTS® 在线折光仪用于控制吸收过程并获得稳定的硝酸浓度值。 阅读应用说明,详细了解硝酸生产工艺。 填写表格,即可下载 PDF 格式的应用说明。 返回所有化学品和同类产品应用 Image Email Address*First Name*Last Name*Country*--Please Select--United StatesUnited KingdomCanadaChinaIndiaJapanAustraliaBrazilFranceGermanyFinland--------------AfghanistanÅland IslandsAlbaniaAlgeriaAmerican SamoaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBoliviaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBrit/Indian Ocean Terr.Brunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Dem.
