Abstract

Due to the increasing demand for natural gas in the world today, transportation of natural gas from different parts of the world has become a necessity. Liquefying the natural gas provides a safer and cheaper alternative for transportation and also increases its storage capabilities. However, it has been accounting for the highest operating cost if compared to the other chain of the industry. Hence liquefaction process has been a key area that constantly in need for development so as to save cost and increase LNG plant capacity through production, which these are, also the objectives to this research. The scopes of studies for this project cover the development of LNG technologies, the cost items that affects the overall cost consumption of the plant, the operating parameters in liquefaction process, equipments' efficiency and also the process lineup. The methodology of this project covers two areas. which are research and stimulation. Research covers the study and collections of information regarding the LNG industry and its development, while stimulation that reflects the process flow of liquefaction will be done in HYSYS. Through HYSYS, comparison can be done from the varies schemes stimulated to obtain the most optimum process output. The flowsheet selected for simulation will be utilising the technology of APCI C3MR as basis. For the study in the power consumption of the plant, the focus lies in the propane refrigerant system where its composition will be manipulated to obtain the temperature output and power required by the compressor. Based on the power obtained, the cost can be calculated to obtain the cheapest operating cost. Nevertheless, further studies and in depth understanding on the fundamentals of liquefaction process is still required in order to develop innovative methods to further increase the capacity, efficiency and consequently the production of LNG in a LNG plant. The enhancement method can be in terms of process and machinery integration advancements.
