20.500.12556/DKUM-22432 SIMULACIJA PROIZVODNJE METANA IZ SINTEZNEGA PLINA S PROGRAMSKIM PAKETOM ASPEN PLUS SIMULATION OF PRODUCTION OF METHANE FROM SYNTHESIS GAS WITH ASPEN PLUS SOFTWARE V svetu se uporablja tehnologija uplinjanja premoga za pridobivanje sinteznega plina, ki je osnovna surovina za proizvodnjo kemikalij, energentov in električne energije. Zaradi visokih cen nafte in zemeljskega plina postaja ekonomsko upravičena proizvodnja metana z uplinjanjem premoga kot alternativno gorivo zemeljskemu plinu. Pri uplinjanju premoga nastaja sintezni plin, ki je v glavnem sestavljen iz ogljikovega monoksida in vodika. Ker sestava sinteznega plina ni primerna za direktno sintezo metana je pred tem potrebno še izvesti reakcijo sinteznega plina z vodo (water gas shift reaction), kjer se ogljikov monoksid z uporabo vodne pare in prisotnosti katalizatorja pretvori v vodik in ogljikov dioksid. Po čiščenju se plinska mešanica vodi v reaktor za metanizacijo v prisotnosti katalizatorja, kjer se proizvaja metan, ki se v nadaljni rabi imenuje sintetični zemeljski plin (SNG) Diplomska naloga vključuje simulacijo vodno-plinske pretvorbe sinteznega plina, izbiro absorbenta metanola za odstranitev CO2 iz sinteznega plina ter simulacijo metanizacije, za pridobivanje sintetičnega zemeljskega plina s programom Aspen Plus® 2006.5. Coal gasification technology is mainly used for synthetic gas production, which is a starting material for chemical, fuel and electricity generation. Due to high oil and gas prices the latest and most economical alternative to natural gas is methane gas production by means of coal gasification. Such a technique is used to produce synthetic gas that contains varying amounts of carbon monoxide and hydrogen. Since synthetic gas composition is, however, not suitable for the direct synthesis of methane, it is necessary to carry out the water gas shift reaction in order to convert carbon monoxide into carbon dioxide and hydrogen, using water vapour and a specific catalyst. The output gas mixture is then passed through catalytic methanation reactor to produce methane which can be further used as synthetic natural gas (SNG). With the process simulation software Aspen Plus® 2006.5, the final section of the BA thesis introduces the simulation of synthesis gas conversion based on steam hydrogasification, the selection of methanol absorbent to eliminate CO2 from this particular synthetic gas, and the simulation of methanation in synthetic natural gas production. procesne naprave načrtovanje procesov uplinjanje sintezni plin absorpcija CO2 vodno-plinska reakcija (WGS) metanizacija simulacija – program Aspen devices process planning of the processes gasification synthesis gas absorption CO2 water-gas shift (WGS) methanation simulation – program Aspen true true false [A.
