“…In terms of liquid desiccant absorption technologies, several glycols have been found to be suitable for commercial applications, such as ethylene glycol, diethylene glycol, tetraethylene glycol, and triethylene glycol (TEG). Among different kinds of liquid desiccants, TEG is the most widely used solvent for absorption, owing to its low volatility, high hygroscopicity, and high thermal stability. , Due to the perfect performance of TEG application in the natural gas dehydration field, numerous research focuses on the TEG dehydration process to improve the dehydrating performances, such as predicting water removal efficiency, , estimating TEG purity with a new method, equipment sizing and type selection, , studies on the influence of solvent purity, , the equilibrium model optimization, the stripping gas injection, − and so forth. Although extensive literature studies are available on the process simulation and parameter optimization of the natural gas dehydration process, none of the researchers focuses on the process optimization aiming at adaption to the rolling exploration of the shale gas field, for which device modularization and relocation as well as environmental performance are the major concerns.…”
