Abstract： In recent years，scale of oil and gas field development is enlarged gradually，natural gas production is increasing year by year，the existing dehydration units cannot meet the production demands，it is very necessary to reconstruct such dehydration units and relative supporting production facilities. Such existing dehydration facilities can be used as triethylene glycol dehydration unit for increasing gas treatment capacity so as to reduce reconstruction costs. Swirl tube separation technology is used in high efficient separator and tray，which can significantly improve liquid-gas separation efficiency. If the high efficient separator is combined with the high efficient tray together，gas treatment capacity can be improved and triethylene glycol loss and hydrocarbon entrainment can be reduced. Application of swirl tube tray in triethylene glycol absorption tower reconstruction can make gas treatment capacity reach up to 160 % of structured packing and 400% of bubble cap tray. Application of swirl tube tray in building new triethylene glycol absorption tower can reduce dimensions of the tower and capital construction cost. It has been shown by experience that swirl tube tray may be widely used in gas dehydration unit with treatment capacity more than 500×104 m3/d.
