湿法磷酸生产工艺 硫酸和磷酸的在线浓度测量和质量监测 磷酸 (H3PO4) 是通过采用湿法或热法工艺加工磷矿石而成的。世界上 80% 的磷酸都是通过湿法工艺制成。湿法工艺包括反应、过滤和浓缩工序。在反应容器中研磨磷矿石并使用硫酸酸化。酸化反应过程中,磷矿石中的磷酸钙转化为磷酸和不可溶的硫酸钙盐 (CaSO4),也就是石膏。 硫酸浓度会影响酸化反应的速度和石膏结晶过程,须保持在 93-98% 之间。此外,对硫酸浓度的控制可确保生产出尽可能高强度的 酸性产物,从而降低蒸发阶段的能耗。 在接下来的过滤工序中将固形物分离出来并清洗,得到浓度为 32% 的 P2O5(约等于 50% 浓度的 H3PO4)磷酸。最后,蒸发酸液以得到浓度为 54% 的 P2O5(相当于 70% 浓度的 H3PO4)工业级酸。如要将磷酸用于食品、制药和化妆品行业,还需进一步提纯,获取更高纯度的磷酸。 维萨拉 K-PATENTS® 在线折光仪有助于 在线实时测量硫酸和磷酸的浓度,消除采样需求 确保仅产出高浓度的磷酸,从而降低 蒸发阶段的能耗 调节反应容器的热负荷能力 控制石膏结晶过程。晶体的大小和形状达到理想状态可以提升过滤工序的效率,进而提高工艺过程的整体生产效率。 通过监测磷酸的最终浓度来降低操作成本 阅读应用说明,详细了解数字传感技术以及如何优化湿法磷酸生产工艺。 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 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.
