Abstract

Nowadays, the exploration of natural gas from oil rig is very important to support world’s demand in many sector. However, natural gas that are obtained from offshore is not free from contaminants such as Carbon Dioxide. High concentration of Carbon Dioxide in natural gas cannot be allowed to be further process due its acidic property which can led to pipeline corrosion. Currently, there are many technologies that have overcome this problem such as by using chemical absorption, physical absorption and membrane technologies. However, most of the current technologies cannot help to remove Carbon Dioxide directly on offshore. Due to that, an efficient and compact separator need to be applied on there. The objectives of this study is to analyze desorption phenomenon and process of dissolved CO2 from water across the converging nozzle by conducting an experiment in the laboratory. Effectiveness of the converging nozzle are also measured from that. Effect of pressure and pressure drop occur across the converging nozzle are the main parameters that affect the desorption rate of CO2 from water. From the study conducted, it is shown that as the pressure set to the system is higher, the pressure drop across the converging nozzle also would be higher. It is also found that desorption process of dissolved CO2 from water increase when the pressure of the system is set at higher value and the pressure drop occur across the converging nozzle is higher.
