Tiivistelmä (eng): | The goal of this Master's thesis was to design and validate inert gas stripping equipment which would be able to measure activity coefficient at infinite dilution for chemical ompounds specially those present in bio-oil. Activity Coefficient at infinite dilution is an important parameter which is considered when designing rigorous thermal separation processes. The motivation of this research is derived by the absence of infinite dilution activity coefficient values for various chemical compounds present in bio-oil. In recent future bio based fuels are looked upon as a viable refuge for the growing worldwide energy crisis. Fast pyrolysis of biomass yields bio-oil which has a high potential to be used as an alternative fuel. Dilutor or inert gas stripping equipment was built as a result of this research. The equipment was validated using Toluene and n-Butanol and infinite dilution activity coefficient values were also reported for Valeraldehyde for which only very few data points are present in literature. The equipment was tested by changing the flow rate of the inert gas and hanging the temperature of the experiment. Effect of hydrophobicity of the chemical compound and effect of vapour pressure of the compounds were also studied. |
