The recovery of light hydrocarbon in liquefied natural gas can improve the quality reduce the dew point of liquefied natural gas and decrease the consummations of oil and gas,which can increase the whole economic benefit of the liquefied natural gas and the benefit of society.The design of chemical engineering process is not only important for flow design and theproduction, but also essential for reducing the experiments consuming and avoiding thesafety-hidden problems. HYSYS is one of the most extensively applied softwares in chemicalsimulations nowadays. It is provided with lots of merits, such as instructing operation,powerful functions. HYSYS is an important tool for complex chemical process-simulation.Therefore, this paper has been made use of HYSYS to simulate static-state process for Shandong recovery of ligh...
