Building a mathematical model of the polymerization reactor is necessary to determine dependencies between input variables, technological mode and output variables ethylene process in an autoclave with stirrer, as well analyze effect design parameters on efficiency. A deterministic developed basis analysis physico-chemical regularities proposed solve these problems. There shown schematic diagra...

Multi-objective optimization of an industrial low-density polyethylene (LDPE) tubular reactor is carried out at design stage with the following objectives: maximization of monomer conversion and minimization of normalized side products (methyl, vinyl, and vinylidene groups), both at the reactor end, with end-point constraint on number-average molecular weight (Mn,f) in the product. An inequalit...

In this research, an experimental study to evaluate nutrient removal from synthetic wastewater by a lab-scale moving bed biofilm process was investigated. Also, kinetic analysis of the process with regard to phosphorus and nitrogen removal was studied with different mathematical models. For nutrient removal, the moving bed biofilm process was applied in series with anaerobic, anoxic and aerobic...

The homogeneously catalyzed hydroformylation of ethylene to propanal using an Rh(H)(PPh3)3(CO) catalyst has been assessed experimentally in a gas–liquid batch reactor and via microkinetic modeling,...

The operation of an industrial semi-batch reactor, in which the bulk chemical EHEC, ethyl hydroxyethyl cellulose, is produced, is studied and simulated. In the reactor a strongly exothermic polymerization reaction takes place followed by a slightly exothermic reaction, and we want to minimize the duration of the operation of the process. Various operational as well as quality and safety related...
