Abstract
A rather hot subject in today’s society is global warming. Both technical progresses and global agreements between nations are much needed to counter this ever growing world problem. In this report a novel CO2-capture system, using the sterically hindered amine 2-amino-2-methyl-1-propanol (AMP) and N-methyl-2-pyrrolidone (NMP) as an organic solvent, is investigated by process simulation in the software Aspen Plus™ using the property method “Non Random Two Liquid” (NRTL). Expected chemical reactions occurring within the system are ionic. Since the property method of NRTL is in general not suitable for ionic reactions the main aim of this study is to examine if acceptable assumptions can be made to simplify the process, making NRTL a viable...

A rather hot subject in today’s society is global warming. Both technical progresses and global agreements between nations are much needed to counter this ever growing world problem.

Expected chemical reactions occurring within the system are ionic. Since the property method of NRTL is in general not suitable for ionic reactions the main aim of this study is to examine if acceptable assumptions can be made to simplify the process, making NRTL a viable option as chosen property method. To do so a full working industrial model of a CO2-capture system was not needed and so the process was simplified to a flash vessel.
Binary interaction for the process were described with NRTL-pair-parameters and Henrys theorem, the latter one accounts for non condensable gases such as CO2. These parameters were regressed from experimental data from various studies of Karlsson, Sanku and Svensson. Pure component parameters were either obtained from literature or estimated using various software’s from molecular structure. Several methods to describe chemical reactions and precipitation products, namely an AMP-carbamate, were evaluated and suitable ones were tested in the process simulations. (Less)
Popular Abstract (Swedish)
Det talas allt oftare om stigande världshav, tropiska stormar och klimatflyktingar. Vi vet alla att vi måste minska våra CO2-utsläpp för att överleva följderna av den globala uppvärmningen. Om det ändå fanns
något sätt att samla upp all CO2 från luften så hade kanske den globala uppvärmningen varit ett minne blott…. Men hör här, denna teknik finns redan idag!
Tekniken kallas CO2-absorptionsteknik med aminen 2-amino-2-methyl-propanol (AMP) och denna studerades i examensarbetet. Tekniken möjliggör att CO2 kan avskiljas från industriella avgaser och fria luften. Denna CO2 kan sedan återanvändas som t.ex. drivgas i sprayflaskor eller som mat till alger som i sin tur kan tillverka biobränsle.
