Abstract:Namen diplomske naloge je določiti optimalni čas pranja pufrnih rezervoarjev, zmanjšati porabo pralne vode in hkrati količino vode, ki se mora očistiti na industrijski čistilni napravi. V sklopu čistilne naprave v podjetju, ki se ukvarja s proizvodnjo pralnih in drugih kemičnih sredstev, imamo na voljo vakuumski uparjalnik, zato želimo maksimizirati porabo destilata namesto vodovodne vode. V vzorcih pralne vode se po pranju opreme še vedno nahajajo površinsko aktivne snovi in druge kemikalije. S sistemskim pristopom vzorčenja in s pomočjo hitrih analiz (pH, motnost, prevodnost, penjenje, kivetni testi za tenzide in sulfate, lomni količnik) smo določili optimalne pogoje pranja za posamezen polizdelek v pufrnem rezervoarju. Pralna voda mora biti po čiščenju opreme bistra, brezbarvna, brez vonja in pene. Poleg tega je zahtevan še nevtralni pH (med 5,5 in 8,5) in lomni količnik vrednosti 0,5 °Brix ali manj. Ugotovili smo, da je prevodnost tisti parameter, ki nam pove zelo veliko o čistosti pralne vode. Po določitvi optimalnih pogojev pranja pri posameznih polizdelkih se je prevodnost namreč gibala v podobnem območju, tj. med 490 µS/cm in 540 µS/cm. Ugotovili smo, da smo pranje največkrat ponavljali v pufrnih rezervoarjih 5 in 7. Ta dva rezervoarja sta zaradi svoje starosti najbolj kritična, saj je poraba pralne vode zaradi večkratnih ponovitev pranj posledično zelo velika. Z uvajanjem protipenilnega sredstva direktno v cev pralne vode smo na zelo penečem polizdelku porabo vode zmanjšali za približno 70 % začetne porabe.

Title:Rationalization of washing process in buffer tanks
Abstract:The purpose of the thesis is to determine the optimal time for washing buffer tanks, to reduce the consumption of washing water and at the same time the amount of water that must be cleaned at the industrial treatment plant. As part of the treatment plant in the company, which is engaged in the production of detergents and other chemical agents, we have a vacuum evaporator available in order to maximize the consumption of distillate instead of tap water. In the washing water samples there are still surfactants and other chemicals present after washing the equipment. Using systematic sampling approach and with the help of fast analyzes (pH, turbidity, conductivity, foaming, cuvette tests for surfactants and sulfates, refractive index), we determined the optimal washing conditions for each semi-finished product in buffer tank. After cleaning of equipment, washing water must be: clear, colorless, odorless and foamless. In addition, a neutral pH (between 5.5 and 8.5) and refractive index of 0,5 ° Brix or less, are required. We found out that conductivity is the parameter which tells a lot about the purity of washing water. After determining the optimal washing conditions for individual semi-finished products, the conductivity was in a similar range, ie. between 490 µS/cm and 540 µS/cm. We found out that washing was most often repeated in buffer tanks 5 and 7. Mentioned two tanks are the most critical due to their age, as the consumption of washing water is consequently very high due to repeated repetitions of washing. By implementing the antifoam directly into the washing water pipe, water consumption on the highly foaming semi-finished product reduced for approximately 70 % of the initial consumption.
