| dc.description.abstract | The liquefaction of the natural gas is one of the important processes in the world.
Nowadays, there are many liquefaction of natural gas technology that has been discovered.
This is because; the human demand on the natural gas production is increasing from day to
day. Now, there are many technologies that have been proposed by the scientist to increase
the production of natural gas in order to fulfill the human need. The example of the
liquefaction of the natural gas technology or process is the PRICO, MR-X, AP-X, AP-N
and C3MR. The AP-N liquefaction of natural gas processes is the new technology that has
been discovered and introduced to world by air product and that why it has been name APN.
This AP-N process is the modification that has been done to the nitrogen expander cycle
technology which used a single component refrigerant. This process used nitrogen N2 for
the process and doesn’t has precooling stage compared to other technology of the
liquefaction process of natural gas. For all information, this AP-N liquefaction process is
specialized for the floating transportation technology such as ship. For the simulation and
analysis for AP-N process, we have chosen the DWSIM open source software in order to
determine the value of coefficient of performance (COP). After finished the simulation and
analysis, we need to make decision whether the result that we get from the simulation is
acceptable or not. If the value that we get is fulfilled the thermodynamic perspective that
means our simulation is success and we can try other liquefaction of natural gas process by
using this software. | en_US |
