Dynamic Simulation of the Lurgi-type Reactor for Methanol Synthesis
نویسندگان
چکیده
The purpose of this work is to develop a reasonably detailed dynamic model of a Lurgitype industrial methanol synthesis reactor so as to determine important simplifications, to identify application/operating model limits, and to preliminary check the feasibility for the Nonlinear Model Predictive Control (NMPC) methodology. To do so, a Partially Differential Equation (PDE) system is formulated and integrated to characterize the main phenomena occurring in this shell and tube boiler-reactor. The PDE numerical solution is performed via certain very performing algorithms (BzzMath library).

AN EQUATION ORIENTED APPROACH TO STEADY STATE FLOWSHEETING OF METHANOL SYNTHESIS LOOP
An equation-oriented approach was developed for steady state flowsheeting of a commercial methanol plant. The loop consists of fixed bed reactor, flash separator, preheater, coolers, and compressor. For steady sate flowsheeting of the plant mathematical model of reactor and other units are needed. Reactor used in loop is a Lurgi type and its configuration is rather complex. Previously reactor ...
متن کاملCFD Simulation of Dimethyl Ether Synthesis from Methanol in an Adiabatic Fixed-bed Reactor
A computational fluid dynamic (CFD) study of methanol (MeOH) to dimethyl ether (DME) process in an adiabatic fixed-bed reactor is presented. One of the methods of industrial DME production is the catalytic dehydration of MeOH. Kinetic model was derived based on Bercic rate. The parameters of this equation for a specific catalyst were tuned by solving a one-dimensional homogenous model using MAT...

In the first part of two section paper, a mathematical model of the fluidized bed reactor in the presence of in-situ water adsorbent for methanol synthesis is assessed. The bubbling two-phase regime is applied to model the fluidization concept. The binary adsorbent and catalyst particles system can be separated from each other based on their density difference. The heavy catalyst particles tend...
