Abstract (eng): | This master's thesis is an investigation of a suitable thermodynamic model for the vapor-liquid equilibrium of binary and ternary mixtures of hydrodeoxygenation of pyrolysis oil. The selected investigative equations of state were PSRK and API-SRK. Of API-SRK two different types of models were examined, namely as the BIPs (binary interaction parameters) were set to zero and by fitted BIPs. Furthermore extrapolations of the original experimental measurements were made by PSRK. The simulations were made by VLEfit -software. Pyrolysis oil components included in the work were partly predetermined pseudo components. In addition product components and other suitable components for the hydrodeoxygenation of pyrolysis oil were selected. Superior models in the simulations were PSRK and the API-SRK (with fitted BIPs) that modelled equally well. API-SRK with BIPs set to zero gave poor results. Extrapolations gave fairly good results. Mixtures containing light gases (hydrogen, methane and carbon dioxide) gave in general the biggest errors. |
Abstract (swe): | Avsikten med detta arbete var att undersöka passliga termodynamiska modeller för gas-vätska jämvikt av binära och tertiära ämnes blandningar för hydrodeoxygenerad pyrolys olja. Målsättningen var att undersöka tillståndsekvationerna PSRK och API-SRK. Av API-SRK utfördes modeller både för optimerade interaktions parametrar och interaktions parametrar som hölls vid noll, dvs. icke optimerade. Därtill presenteras också extrapolations utforskningar av de originella experimentella mätningarna för PSRK. Simulationerna utfördes av programvaran VLEfit. Komponenterna för arbetet bestod av förhands valda pseudo komponenter och produkt komponenter till dessa. Ytterligare valdes också andra komponenter som ansågs prassliga för den undersökta processen. Bästa modellerna för ändamålet outfördes av PSRK och optimerad APl-SRK, vilka gav praktiskt taget lika resultat. API-SRK vars interaktions parametrar hölls vid noll fungerade sämst. Extrapolationerna gav bra resultat. Överlag gav ämnesblandningar som inkluderade väte, metan och koldioxid mest avvikelse. |
