20.500.12556/DKUM-13536 PROIZVODNJA FORMALINA Z MANJŠO PORABO POGONSKIH SREDSTEV PRODUCTION OF FORMALIN WITH LOWER UTILITIES Za družbo Nafto Petrochem d.o.o, smo v diplomskem delu naredili raziskavo za proces proizvodnje formalina. Naša glavna naloga je bila učinkovitejša proizvodnja formalina, zato smo se usmerili v toplotno integracijo procesa. V delno integriranem procesu smo razpoložljivo toploto uporabili za segrevanje obstoječega srebrovega procesa in s tem zmanjšali porabo pogonskih sredstev, ter proizvodnjo nizkotlačne pare v oksidnem procesu. Simulacije smo izvajali z računalniškim procesnim simulatorjem Aspen Plus, v katerem smo spreminjali parametre, da smo dobili rezultate, katere smo nato podrobno analizirali. Z metodo analize uščipa smo podrobno preučili vse pridobljene podatke in ugotovili, kateri od podatkov se najbolj približajo vrednosti 1 maksimalne možne toplotne integracije v procesu. For company Nafta Petrochem d.o.o, we made a research study for the process production of formalin. Our main task was more efficient production of formalin, so we focus on thermal integration of the process. In partly integrated process, we used the available heat of the silver process and so we reduce the consumption of the utilities, and producing low pressure steam in the oxide process. Simulations were performed with a computerized simulator Aspen Plus procedural, in which we change the parameters and then we got results, which we then analyzed in detail. By pinch analysis, we examine in detail all the information obtained and determine which of the data is most closer to the maximum possible integration value of 1 in the process. toplotna integracija pogonska sredstva proizvodnja nizkotlačne pare maksimalna možna toplotna integracija procesa. heat integration power resources producing low pressure steam maximum possible integration process. true true false [M.
