Analiza postopka uplinjanja v laboratorijski uplinjevalni napravi

Perne, Žiga (author), Seljak, Tine (mentor)

Proces uplinjanja je velja za eno izmed obetavnih tehnologij za pretvorbo organskih materialov z vsebnostjo ogljika v pline z uporabno kalorično vrednostjo ali kemikalije, uporabljene v industrijskih procesih. V ospredje prihajajo nekonvencionalni materiali kot sta biomasa in odpadki, ki pa s seboj prinašajo številne tehnične izzive. V nalogi je predstavljen postopek razvoja laboratorijske naprave za uplinjanje različnih trdnih goriv, ki je osnovan na teoretičnih preračunih procesa uplinjanja ter izkušnjah, dostopnih v znanstveni in strokovni literaturi. Z razvito laboratorijsko napravo je nato opravljeno vrednotenje procesa uplinjanja s poudarkom na analizi globalnih termodinamskih parametrov, vključno s temperaturami in masnimi tokovi. Dodatno je za zmanjševanje vsebnosti klorovih in žveplovih spojin v nastalem produktnem plinu ovrednoten tudi inovativni pristop čiščenja sinteznega plina, ki se zanaša na uporabo kalcita kot reagenta, ki prestreže omenjene spojine. Rezultati potrjujejo ustreznost zasnove laboratorijske naprave ter podajajo ustrezni interval masnih tokov za doseganje stabilnega delovanja. V identificiranem območju se kot delno ustrezna izkaže tudi rešitev z dodajanjem kalcita v gorivo, ki bistveno zmanjšuje vsebnost kontaminantov v nastalem produktnem plinu.

• Title: Analysis of the Gasification Process in a Laboratory Gasification Device

Abstract

The gasification process is considered to be one of the promising technologies for the conversion of organic carbonaceous materials into gases with a usable calorific value or for synthesis of chemicals used in industrial processes. Unconventional materials such as biomass and waste are coming are now emerging and are bringing with them a number of technical challenges. The thesis presents the development process of a laboratory-scale device for gasification of various solid fuels. The design is based on theoretical calculations of the gasification process and experience available in scientific and professional literature. With the developed laboratory device, an evaluation of the gasification process is carried out with an emphasis on the analysis of global thermodynamic parameters, including temperatures and mass flows. In addition, an innovative approach to synthesis gas purification has been evaluated, which reduces the concentrations of chlorine and sulphur compounds in the formed product gas using calcite as a reagent to intercept said compounds. The results confirm the adequacy of the design of the laboratory device and give the appropriate intervals of mass flows to achieve stable operation. The approach of calcite addition also proves partially appropriate in the identified range, significantly reducing the content of contaminants in the resulting product gas.
