magistrsko delo
Abstract
Namen magistrskega dela je bil izvesti optimalno povezavo različnih tehnologij čiščenja odpadnih oljnih emulzij (OOE) za zmanjševanje okoljske obremenitve oziroma doseganje ekoloških standardov v obliki zakonske regulative, ob upoštevanju ustrezne ekonomske učinkovitosti. Izdelali smo optimizacijski model in z uporabo mešanega celoštevilčnega linearnega programiranja (MILP) posamezne sklope v procesu čiščenja združili v enoten tehnološki sklop – superstrukturo. Za sledenje učinkovitosti čiščenja OOE smo izmed zakonsko predpisanih parametrov, ki jih je potrebno spremljati v okviru obratovalnega monitoringa odpadnih vod, izbrali parameter KPK – kemijsko potrebo po kisiku, katerega mejna vrednost za izpuščanje odpadnih voda v vodotoke znaša 120 mg O2/L. Poleg tega, da smo uporabili celoten spekter tehnologij čiščenja OOE, smo z namenom pridobitve različnih kombinacij posameznih separacijskih tehnik, izvedli analizo parametrov s spreminjanjem vrednosti vhodnega KPK med 1.000 in 110.000 mg O2/L. V magistrskem delu je prikazano učinkovito kombiniranje tehničnih rešitev in ekonomskih kazalcev učinkovitosti postopkov obdelave. Rezultati optimiranja kažejo, da se z naraščajočimi vrednostmi parametra KPK vhodnega toka povečujejo investicijski in obratovalni stroški, vključno s porabo električne energije, kar bistveno vpliva na ekonomsko učinkovitost čiščenja OOE.

Secondary title: |
SYNTHESIS OF SEPARATION PROCESS FOR WASTE TREATMENT OF OIL-IN-WATER EMULSIONS |
Secondary abstract: |
The aim of this master thesis was to synthesize economically efficient combinations of different separation techniques for the treatement of oil-in-water emulsions (OWE) to reduce the environmental burden and achieve ecological standards complying legal regulations. We have combained individual cleaning technologies into a single technological set - superstructure. Then, we have developed a mixed integer linear programming (MILP) model fof the defined superstructure. For tracking the effectiveness of cleaning OWE, we selected the parameter COD - chemical oxygen demand, which is one of basic parameters to be monitored. In the context of the operational monitoring of wastewater, we set the threshold for the discharge of waste water to 120 mg O2/L. We used the full spectrum of cleaning technologies in order to identify different combinations capable of treating OWEs with different input COD concentrations. We carried out an analysis of process parameters by varying the values of input COD between 1.000 and 110.000 mg O2/L. The master thesis indicates that economically effective combination of technical solutions can be identified. The results of the optimization show that with increasing inlet COD concentration investment and operating costs, including electricity consumption, are also increasing, which significantly affects the economics of the OWE treatment process. |
