摘　　要：辛醇装置以合成气(CO+H_(2))、丙烯为原料,合成气中氢碳比不稳定,变化频繁,根据原料中氢碳比(H_(2)/CO比)变化及时准确补充氢气,是羰基合成反应平稳控制的关键。代表性的国产先进控制(APC)技术有石化盈科PROCET-APC、中控APC Suite。以齐鲁石化第二化肥厂辛醇装置为工业应用背景,为实现辛醇氢碳比自动控制,采用石化盈科PROCET-APC先进控制软件设计一个氢碳比控制器:(1)氢碳比控制器投用后表现出良好的鲁棒性能,实现了高压氢气自动控制,投用率一直保持在95%以上,减轻了操作人员劳动强度。(2)辛醇氢碳比和反应器R101一氧化碳含量平稳性明显提高,波动方差分别降低-76.43%和-57.27%。(3)辛醇氢碳比的平稳控制,提高了丙烯效率,降低了羰基合成反应中丙烯的单耗。实施结果表明先进控制在辛醇装置氢碳比上的应用取得了显著的效果。Octanol plant uses syngas(CO+H_(2))and propylene as raw materials.The hydrogen-carbon ratio in syngas is unstable and changesfrequently,so timely and accurate hydrogen replenishment according to the change of hydrogen-carbon ratio in raw materials is the key to the stable control of oxo-synthesis reaction.Representativedomesticadvanced process control(APC)technologies include PCITC's PROCET-APC and SUPCON's APC Suite.Taking the octanol plant in theNo.2Fertilizer Factoryof SINOPECQilu Petrochemical Company as the industrial application background,a hydrogen-carbon ratio controller was designed by using PROCET-APCadvanced control software to achieve the automatic control of hydrogen-carbon ratio in octanol plant.Firstly,the hydrogen-carbon ratio controller has shown good robustness since it was put into use.The automatic control of high-pressure hydrogen was achieved,and the utilization rate has remained above 95%,reducing the labor intensity of operators.Secondly,the stability of hydrogen-carbon ratio in octanol plant and carbon monoxide content in reactor R101was significantly improved,and the fluctuation variance was reduced by-76.43%and-57.27%,respectively.Thirdly,the stable control of hydrogen-carbon ratio in octanol plant improved the efficiency of propylene and reduced the unit consumption of propylene in oxo-synthesis reaction.The results show that the application of advanced process control in controlling hydrogen-carbon ratio in oc-tanol plant has achieved remarkable results.
