- 针对某石化公司 2套丙烯腈装置提负荷后液氨供应不足的问题，对合成氨装置实施氮压机出口增设高压氮气管线的技术改造，破解其原料氮气供应瓶颈、释放产能。介绍了项目立项背景、改造方案、实施过程及投用效果，通过对比技术改造前后工艺参数、设备运行状态与能耗指标，验证了技术改造的可行性和有效性。结果表明，技术改造后合成氨装置液氨产能成功达到 24×104 t/a，最高瞬时产量 31 t/h，液氨供应完全匹配丙烯腈高负荷生产需求[1] ，既保障丙烯腈实现最大效益，也实现全厂系统物料平衡；且装置设备运行稳定、能耗优于设计值，项目投资控制良好，增效益约 921×104 元/a。该项目为解决上下游装置产能匹配、实现系统整体效益最优提供了可借鉴的技术方案，推广价值较高。In view of the insufficient liquid ammonia supply after the load increase of two sets of acrylonitrile plants in a petrochemi⁃cal company, a technical renovation was carried out on the ammonia synthesis plant by adding high-pressure nitrogen pipelines atthe outlet of nitrogen compressors, which broke the bottleneck of raw material nitrogen supply and unlocked production capacity.This paper elaborates on the project approval background, renovation scheme, implementation process and commissioning effects.By comparing the process parameters, equipment operating conditions and energy consumption indicators before and after the tech⁃nical renovation, the feasibility and effectiveness of the renovation were verified.The results show that after the technical transforma⁃tion, the liquid ammonia production capacity of the ammonia synthesis plant has successfully reached 240,000 tons per annum witha maximum instantaneous output of 31 tons per hour. The liquid ammonia supply can fully meet the high-load production demand ofacrylonitrile units, which not only ensures the maximum economic benefits of acrylonitrile production but also realizes the overallmaterial balance of the whole plant. In addition, the plant operates stably with energy consumption lower than the designed value,and the project investment is well controlled, bringing an annual economic benefit increase of approximately 9.21 million yuan. Thisproject provides a referable technical solution for solving the production capacity matching problem of upstream and downstreamplants and optimizing the overall system benefits, possessing high promotion and application value
