【正文】 ber at the top of each tray in turn flow down the tower through the overflow pipe, the water vapor absorption in the tower upward flow of gas. Glycol (rich glycol) to suck in water discharged from the bottom into the reboiler on distillation capitals, after the preheat coil in poor glycol buffer through the flash tank filter department. This design is mainly the dehydration of the main monomer equipment design, including the absorber, flash tank, filter separators, glycol regeneration and other design includes the size of all equipment, material balance, heat balance and equipment water dew point of natural gas≤ 10℃ in this design process in the design conditions. Keywords: natural gas processing。 equipment design 500萬方 /年天然氣脫水裝 置的工藝設(shè)計(jì) I 目錄 1 緒 論
