Abstract

U kemijskoj industriji, u procesu regeneracije otpadnih otapala najčešće se koristi postupak destilacije. Procesom destilacije dobivaju se dva produkta. Primarni produkt je destilat/regenerat koji je konvencionalno primjenjiv, odnosno može se koristiti kao novi proizvod. Destilacijski mulj dobiva se kao sekundarni produkt te ostaje neiskorišten i klasificira se kao opasan otpad kojeg je potrebno zbrinuti. Obzirom da klasično zbrinjavanje opasnog otpada nije u skladu s ciljevima kružnog gospodarstva, destilacijskom mulju tražila se primjena u obliku novog proizvoda. Prema porijeklu zaprimljenih otpadnih otapala te fizikalno-kemijskoj karakterizaciji destilacijskog mulja, zaključeno je kako je destilacijski mulj po svom sastavu i svojstvima sličan komercijalnom antikorozivnim premazima. U svrhu izrade ovog diplomskog rada, obrađena su određena fizikalno-kemijska svojstva destilacijskih muljeva, a provedena su ispitivanja mehaničkih svojstava prionjivosti i pokritnosti te reološka ispitivanja viskoznosti i krivulje toka.
Također, usporedno su ispitani i neki komercijalno dostupni antikorozivni premazi na temelju čega je donesen zaključak o perspektivnosti korištenja destilacijskog mulja kao antikorozivnog premaza.

Abstract (english)

In the chemical industry, distillation is the most common process in waste solvents recovery. Distillation results in two products. The primary product is a distillate/regenerate that is conventionally applicable, meaning it can be used as a new product. Distillation sludge is obtained as a secondary product, and it remains unused and is classified as hazardous waste that needs to be disposed. Considering that the disposal of hazardous waste does not match the circular economy targets, a new purpose was sought for the distillation sludge in a form of new product. By the origin of the received waste solvents and the physical-chemical classification of the distillation sludge, it was concluded that the distillation sludge was similar to commercially available anticorrosive coatings in its composition and properties. For the purpose of this thesis, some physical-chemical properties of the distillation sludge were processed, and, along with mechanical properties such as coverage and adhesion, rheological tests of viscosity curve and flow curve were carried out for the distillation sludge.
Also, some commercially available anticorrosive coatings were also examined in parallel what lead to a conclusion on the prospects of using the distillation sludge as an anticorrosive coating.
