Abstract

Diplomsko delo prikazuje študije možnosti tehnologij za zajemanje CO2, njegovo skladiščenje in možno uporabo oz. predelavo z upoštevanjem ekonomskih, obratovalnih in okoljskih vidikov. Z uporabo ekonomskih kriterijev, ki upoštevajo časovno vrednost denarja, smo dobili realnejše ocene za sprejemanje odločitev o upravičenosti tehnologij za zajemanje, skladiščenje ter uporabo CO2 pri različnih višinah davka na CO2. V literaturi smo zasledili, da je smiselno preučiti modelne primere proizvodnje alkenov v državah, ki imajo veliko proizvodnjo in porabo premoga, velik uvoz nafte, visoko povpraševanje po alkenih in visoko stopnjo onesnaževanja z emisijami CO2. V diplomskem delu smo obravnavali modelne primere, ki vključujejo primerjavo proizvodnje alkenov iz premoga in nafte, iz premoga s tehnologijo zajemanja in skladiščenja CO2 ter iz premoga ob souporabi zemeljskega ali koksnega plina, ki sta primera uporabe tehnologij zajemanja in uporabe CO2. Rezultati neto sedanje vrednosti, ki vključujejo okoljski kriterij izpusta CO2 na tono proizvedenih alkenov kapacitete od 0,7 Mt/a do 1,5 Mt/a, kažejo na upravičenost vlaganja v procese proizvodnje alkenov iz premoga ter njihovo povečevanje, kljub večjim emisijam CO2, saj vpliv stroškov uvoza vhodnih surovin pri procesih proizvodnje alkenov iz nafte presega vpliv davka na CO2. Ugotovili smo, da je za zmanjšanje izpusta emisij CO2 iz procesov proizvodnje alkenov iz premoga smiselna vpeljava tehnologij zajemanja in skladiščenja CO2, katere rezultati, zaradi primerljivosti s procesi proizvodnje alkenov brez emisij CO2, kažejo na okoljsko upravičenost investicij. Tudi vpeljava tehnologij zajemanja in uporabe CO2, v primeru procesov proizvodnje alkenov iz premoga ob souporabi koksnega plina, kaže na okoljsko in ekonomsko upravičenost investicij pri vseh obravnavanih višinah davka na CO2 zaradi visoke stopnje zajemanja in ponovne uporabe CO2 pri tvorbi produktov ob souporabi koksnega plina, ki ga industrija obravnava kot odpad.

Secondary title:	Feasibility studies of CO2 capture technologies
Secondary abstract:	This thesis shows the feasibility studies of technologies for CO2 capture, storage and usage, taking in to account the economic, operational and environmental aspects. By using economic criteria which take into account the time value of money, we get a more realistic assessment for making decision on the viability of technologies for CO2 capture, storage and usage at different heights of the carbon tax. In the literature we observed that it is reasonable to consider a model examples of olefins production in countries, that have a great production and consumption of coal, large import of oil, high demands for olefins and high level of pollution, caused by CO2 emissions. In this thesis we discuss about model examples, including the comparison of coal-to-olefins and oil-to-olefins production, coal-to-olefins production with CO2 capture and storage technology and natural gas or coke-oven gas assisted coal-to-olefins production as example of CO2 capture and usage technology. The results of the net present value, which include environmental criteria of CO2 emissions per ton of olefins in the production from 0,7 Mt/a to 1,5 Mt/a, show the eligibility of investing in coal-to-olefins process, as well as its increasing production despite higher CO2 emissions, because of the cost of input materials at oil-to-olefins process exceeds the impact of the carbon tax. We found that, in order to reduce CO2 emissions from coal-to-olefins process it is applicable to introduce CO2 capture and storage technologies, the results of which, due to the comparability with the processes of production olefins without CO2 emissions, indicate the environmental viability of investments. Also the introduction of the CO2 capture and usage technologies, in the case of gas assisted coal-to-olefins processes, they indicate that the environmental and economic viability of investments at all considered prices of carbon tax due to high level of CO2 capture and usage in forming products with assisted coke-oven gas, which is treated as a waste within the industry.
