Energetic analysis on MR-X process for Liquefaction of natural gas using open source software

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. The liquefaction process requires the natural gas to be cooled using various methods of cryogenic processes and also be depressurized to atmospheric conditions for easier and safer storage. This paper analyzes MR-X process for the liquefaction of natural gas based on the energetic analysis. The MR-X process that is analyzed in this work is assumed to be in Qatar. The research has some problems need to be considered, such as limitation in the use of DWSIM software and paid software such as ASPEN Plus is quite expensive. The objective also must be considered, such as the data from software, Coefficient of Performance value, and similarity in value of enthalpy and entropy. For the results and analysis, the value on power required, heat rates, enthalpy, entropy and COP must be calculated in order to analyze the MR-X process. As a conclusion, all the objective must be achieved, in order to decide whether the research is success or vice versa.
