Investigation of energy saving for Lurgi type methanol reactor
In this article the Lurgi type methanol synthesis reactor mathematics models are found by using one-dimensional homogeneous model and two-dimensional homogeneous model respectively, in which CO and CO2 parallel hydrogenation reaction are regarded as the key reaction, CO and CO2 as the key components. Then it is calculated by double-rate model. At the same time based on the L-H-H-W double-rate model, the intrinsic kinetics model is also found to perfect the simulation algorithms for the dispersion of the temperature and compose in reactor, and by which if the reaction temperature is altered properly under the allowed temperature extension of catalyst, more used heat can be reclaimed for energy saving. Finally this article takes an example of Lurgi type methanol synthesis industrial process simulation which can produce 80,000 ton methanol annually to get the optimal feed temperature, for the more, the methanol content and byproduct steam pressure both are enhanced.
