چکیده مقاله:

Gas dehydration is the process of removing water vapor (moisture) from natural gas streams to meet sales specifications and to prevent hydrate formation and corrosion in transmission pipelines. There are some techniques for dehydrating natural gas but using glycols family is more conventional for this purpose. In this article, with the aid of computer simulation software (HYSYS), two different types of glycols include triethyleneglycol (TEG) and diethyleneglycol (DEG) have been simulated to dehydrate a specified natural gas stream. Then for each case study, energy consumption in the dehydration unit, glycol losses during the operation, purity of the regenerated glycol, and the amount of water content in dehydrated natural gas have been calculated and finally by considering the process constraints and comparing the above criteria it is concluded that using TEG is the best choice for dehydrating the given natural gas stream.
