Control system for low-energy ammonia processes

合成氨厂的节能控制，因受过程变送器特别是在线组分分析器的性能影响，长期难以构成精度较高的控制系统．本文讨论采用Ｑｕｅｓｔｏｒ高速过程多回路。

Owing to the performances of measuring transmitters and on-line composition analyzers, it is hardly to make up a high precision control system for low-energy ammonia processes for a long time. This article bears on the application of instrumentation with the multi-loop and multi-component Questor analyzer used for high speed process and the distributed control system (DCS) to low-energy ammonia processes.
