摘要
山东华鲁恒升化工股份有限公司40万t/a CO2气提法尿素装置在原料气CO2进入尿素高压系统前设置了脱氢装置,以提高尿素装置的安全性。介绍了脱氢催化剂的工作原理和物化性能;简述了脱氢装置的工艺流程;总结了脱氢装置的运行情况;提出了应用CO2脱氢技术时应注意的相关事项。
In order to increase the safety of urea plant, the de-hydrogen device was arranged in the urea plant with CO2 stripping method with a ca- pacity of 400,000 t/a of Shandong Hualu Hengsheng Chemical Engineering Stock Company Ltd. , before the raw gas of CO2 entered into high pressure system of urea. Author has introduced the working principle and the physical and chemical properties for de-hydrogen catalyst; has briefly described the process flow of the de-hydrogen device; has summarized the running situation of the de-hydrogen device; has presented the related matters to be noticed in case of applying of CO2 de-hydrogen technology.
