Physical Properties Analysis of Aqueous Blends of Potassium Carbonate and Piperazine as CO2 Capture Solvent

III
ABSTRACT
It is widely known that carbon dioxide (CO2) is one of the major greenhouse gas (GHG) contributors. It is very important for the industries, such as oil and gas, to reduce the amount of emission to the atmosphere. There have been many researches and studies conducted in order to come up with the most effective absorber for CO2 capture. Potassium carbonate is being looked into by the industry as a potential solvent for absorption of CO2 to replace alkanoamines due ti its ability to resist oxidation degradation, low volatility due to its ionic structure and low binding energy. The introduction of promoter like piperazine to potassium carbonate helps to further enhance the CO2 solubility effect by acting as catalyst to speed up the absorption process. In this project, the physical properties of aqueous blend solution of piperazine activated potassium carbonate are studied. The properties are measured over the wide range of temperature of (20-80) ˚C. The objectives of this project are; 1. To study on the effect of the temperature change on the properties of the blends (PC+PZ); 2. To study on effect of concentration change on the properties of the blends (PC+PZ). 3. To compare the results with the conventional blend solvent, Methyl-Diethanolamine (MDEA). This project is an experimental based project and the time period given, the experimental work covers the physical properties analysis which consists of determination of the density and viscosity over various concentrations and temperature of the blends. Based on the observation of this project, the density and viscosity of piperazine activated aqueous potassium carbonate increases as the concentration of piperazine increases. It is also been notices that the density and viscosity decreases with the increasing temperature.
