Liquefaction of natural gas

Includes bibliographical references (page 68)This project describes concepts of refrigeration cycles\ud and gives an example of designing a process to liquefy\ud natural gas. In fact, the determination of the\ud refrigeration cycle to be used is very tedious because\ud there are many factors to be considered such as\ud geographical location, gas producing rate, investment cost,\ud etc. In addition, there is a lot of effort needed in\ud computer simulated calculations to optimize the process. I\ud am not going to discuss how to pick up a refrigeration\ud cycle nor how to optimize a process in this project. I am\ud going to emphasize theoretical discussion and a process\ud design technique. Although it is a computer era, all of the\ud design and optimization are done by pre-programmed\ud computer, since a process engineer should know how to size\ud equipment such as heat exchanger, compressor, vessel, etc
