The industrial data for a packed reactor (consisting of 1620 tubes of 7 m long) are the basis of this study. At first, the industrial reactor is simulated achieving excellent agreement with plant data. Then, the instability region is defined as a boundary in the conversion-temperature diagram and defines the conditions that must be avoided during reactor operation. The optimization of the operational conditions is performed based on the optimal temperature progression from the iso-reaction rate curves. Finally, it was found that the cooling fluid must be at 230 °C and that the heat transfer coefficient must guarantee a value of 118 J/(s.K.m2).spahttps://v2.sherpa.ac.uk/id/publication/issn/0716-8756Heat transferMethanolOptimizationSynthesis gas manufactureIndustrial reactorsInstability analysisLurgi reactorMethanol productionMethanol synthesisOperational conditionsSimulationTemperature diagramCurve fittinginfo:eu-repo/semantics/article2021-04-16Gómez, M.Á.Dobrosz-Gómez, I.Gilpavas, E.10.4067/S0718-07642016000300016
