石油炼化企业的连续重整装置中氨压机是氨制冷系统中的重要设备，氨压机控制系统部分的设备是现场就地的，自开工以来已经运行10年之久，加之公司临近海边，腐蚀严重，控制系统硬件面临备件停产等因素。因此，该设备控制部分的改造意义重大。根据设备的操作说明及工艺上使用要求整理，仪表控制部分的分析，总结整理出机组的控制点表，开停机逻辑，机组主要控制，最后阐述了改造后控制系统的硬件配置、系统配置、人机画面。%Ammonia compressor is an important equipment in the ammonia refrigeration system of continuous reforming unit in oil refinery, control system equipment part of the ammonia compressor is the scene in situ, since the construction has been running for ten years,and company is near the sea, corrosion is serious, control system hardware face such as spare parts production and so on. So the equipment control section reconstruction is of great significance. In this paper, according to the requirements of the equipment instructions and process used on finishing, the analysis of the instrument control part, sort out control points table of the unit, logic, mainly controls, Finally elaborated the modified hardware configuration of the control system, system configuration, man-machine picture.
