The design of an industrial CSTR to produce ethylene glycol using k from the batch experiment. The use of a laboratory batch reactor to determine the specific reaction-rate constant, k, for the liquid-phase reaction to form ethylene glycol. We have chosen four different reactions and four different reactors to illustrate the salient principles of isothermal reactor design using conversion as a variable, namely Both batch reactor times and flow reactor volumes to achieve a given conversion will be calculated. Conversion is the preferred parameter to measure progress for single reactions occurring in batch reactors (BRs), CSTRs, PFRs, and PBRs.
#Polymath program p5 16 software#
The most easy program to use for solving those examples is Polymath software package.In this chapter, we use the mole balances written in terms of conversion, shown in Chapter 2, Table S2-1, to study isothermal reactor designs. Results based on the examples and the connections found have shown that the end solutions are practically the same.
The description of four of these examples also displays the connection between the packages. The examples listed above are solved by using all three software packages. The seventh example involves the estimation of the parameters of Wagner equation for vapour pressure of propane with non-linear regression. The sixth example requires the estimation of parameters of polynomial equation for heat capacity of butane with the polynomial regression. The following, fifth case involves a transformation of glucose into gluconic acid by calculating a system of differential equations. The fourth example involves the calculation of the volume of the flow reactor using a simple differential equation. The third example is a case of thermal dissolution of light hydrocarbons into olefins, the mathematical model for this example is the system of non-linear equations. The second example involves a calculation of streams and contents of streams of natural gas from the evaporator, the basis for which is the solving of a non-linear equation. The mathematical model for this problem is the system of linear equations. The first is the calculation of the outgoing concentration of the reactant in a cascade of four different mixing reactors. The thesis presents the use of these packages and how these are connected using seven examples. The aim of this thesis was to study and test three software packages - Polymath, Matlab and Excel with regard to the way they help solve problems arising in chemical technology. THE USE OF NUMERICAL PROGRAM PACKAGES POLYMATH, MATLAB AND EXCEL IN CHEMICAL ENGINEERING Postavite miškin kazalec na naslov za izpis povzetka. Numerične metode, sistem enačb, linearne enačbe, nelinearne enačbe, diferencialne enačbe, regresija, program Polymath, program Matlab, program Excel Najbolj enostaven za uporabo navedenih primerov je programski paket Polymath. Iz primerov in povezav ugotovimo, da so dobljene rešitve praktično enake. Na štirih primerih je prikazana tudi povezava med paketi. Navedeni primeri so rešeni z vsemi tremi programskimi paketi. V sedmem primeru so ocenjeni parametri Wagnerjeve enačbe za parni tlak propana z nelinearno regresijo. V šestem primeru, je treba oceniti parametre enačbe za molsko toplotno kapaciteto butana s polinomno regresijo.
Peti primer je primer pretvorbe glukoze v glukonsko kislino, kjer je potreben izračun sistema diferencialnih enačb. V četrtem primeru gre za izračun prostornine cevnega reaktorja z navadno diferencialno enačbo. Matematični model je sistem nelinearnih enačb. Tretji primer je primer termičnega razcepa lahkih ogljikovodikov v olefine. Drugi primer je izračun iztokov in sestave iztokov naravnega plina iz uparjalnika, kjer gre za reševanje nelinearne enačbe. Matematični model je sistem linearnih enačb. Prvi primer je izračun izhodnih koncentracij reaktanta v kaskadi štirih mešalnih reaktorjev. Uporaba paketov in njihova medsebojna povezava je predstavljena na sedmih primerih. Na področju reševanja kemijsko-tehnoloških problemov smo želeli spoznati in preizkusiti tri programske pakete Polymath, Matlab in Excel. FKKT - Fakulteta za kemijo in kemijsko tehnologijo
