Abstract

Ob neprestanem onesnaževanju okolja je potrebno stremeti k učinkovitim rešitvam glede zmanjševanja odpadnih snovi in izpustov v ozračje. Ponovna uporaba odpadnih plinov predstavlja potencialno rešitev za prihodnost. Proizvodnja amonijaka poteka iz vodika in dušika, ki ju lahko pridobivamo iz odpadnih plinov, natančneje iz dimnih plinov in z uplinjanjem plastike. S tega vidika se zdi uplinjanje odpadne plastike kot dobra rešitev, saj hkrati zmanjšujemo količino odpadnih snovi, poleg tega pa obstaja možnost uporabe plinov, ki pri tem nastajajo. Namen diplomskega dela je raziskati področje ponovne uporabe odpadnih plinov za pridobivanje amonijaka, simulirati proces proizvodnje amonijaka ter določiti kritične procesne parametre, ki ključno vplivajo na učinkovitost procesa. Predstavljene so računalniške simulacije proizvodnje amonijaka, ki so izvedene s programskim paketom Aspen Plus. Rezultati kažejo, da dobimo večjo količino želenega produkta na iztoku ob izbiri relativno nižjih obratovalnih temperatur ter relativno višjega obratovalnega tlaka v reaktorju in separatorju.

Secondary title: Ammonia production from waste gases
Secondary abstract: Constant environmental pollution is the reason why effective solutions must be sought to reduce waste and emissions. The reuse of waste gases is a potential solution for the future. Ammonia is produced from hydrogen and nitrogen, which can be obtained from waste gases, more precisely from flue gases and gasification of plastics. From this point of view, gasification of plastic waste seems to be a good solution, as at the same time we reduce the amount of waste materials and, in addition, there is the possibility of using the gases produced. The purpose of this study is to research the reuse of waste gases for ammonia synthesis, to simulate the process of ammonia production and to determine the critical process parameters that have a key impact on the efficiency of the process. Computer simulations of ammonia production are presented which were conducted using Aspen Plus software package. The results show that by choosing relatively lower operating temperatures and a relatively higher operating pressure in the reactor and separator, a larger amount of the desired product is obtained at the outlet.
