硝基胍喷雾连续干燥工艺风险研究

摘要硝基胍生产过程中，传统的干燥工序采用蒸汽烘箱干燥。该工序作业现场安全隐患较大。国家特种超细粉体中心正在研发的高压喷雾连续干燥工艺及设备，能够很好的解决传统干燥过程的诸多问题。本文尝试对硝基胍喷雾连续干燥工艺过程进行系统风险分析，给出改进措施和建议。首先，将硝基胍连续干燥工艺与传统干燥工艺进行对比；其次运用故障假设法进行分析列举；运用危险可操作性分析法，对工艺中的重要环节进行分析，提出改进措施；运用事故树分析法，创建工艺中两个关键环节的事故树，对其进行分析，并在此基础上提出一些确保工艺安全的安全控制措施，以实现对硝基胍喷雾连续干燥工艺单元的最优安全控制。43215

Title Risk of Nitroguanidine continuous spray drying process

Abstract

Nitroguanidine production process, the conventional process using a steam drying oven dried. The process of job site safety hazards bigger. National Special Superfine Powder Center is developing a high-pressure spray continuous drying technology and equipment, can solve many problems of the conventional drying process. This paper attempts to nitroguanidine continuous spray drying process systematic risk analysis, improvement measures and recommendations are given. First, nitroguanidine continuous drying process with conventional drying process compared; Second, the use of fault analysis method assumptions include; use of hazard operability analysis, the process is an important part of the analysis, we suggest improvements; using Fault Tree Analysis method, create process fault tree two key aspects, analyze, and make some security controls to ensure process safety measures on this basis, in order to achieve optimal security control for continuous nitroguanidine spray drying process unit.
