摘要：天然气中含有水分，会导致设备的堵塞，因此需要脱水。三甘醇对天然气有很强的脱水能力，热稳定性好。使用板式塔作为天然气脱水系统的装置是当前世界上所广泛采取的方法。
本课题的设计对象是一内径为1500 mm，塔高4800 mm，设计温度为38℃，设计压力6.05MPa，板间距为600 mm的板式脱水塔。在设计中对脱水塔的各部件的选用进行了比较。重点对塔体所受的各种应力进行了校核，并对塔体可能承受的风压和地震载荷进行了计算和校核以及对塔的开孔进行了补强设计。23592
有一个合理良好的塔结构设计的话对天然气的脱水意义将体现出最大化的效率。因此，塔的设计直接影响了脱水能耗和天然气能源的利用率，这两者是相辅相成，有机统一的。

The Design of the TEG Dehydration Tower
Abstract: The natural gas contains water. It can bring about the blockage of the equipment. So we use method of absorption to dehydrate. TEG has a strong dehydrated capability of natural gas, and it has the sound heating stability. The plate tower as a device for natural gas dehydration system is widely adopted in the world.
The design of this subject is an inner diameter of 1500mm, height of 4800 mm, design temperature of 38 ℃, and the design pressure is 6.05MPa, plate spacing of 600 mm tray dehydration tower. In this design, the working theory of the dehydration tower is briefly stated. Not only a comparison of each part’s have a reasonable selection, but also all the stress on the body of the tower is also checked. Then the impossible load by the body of the tower design and the holes of the tower are reinforced in this design.
There is a tower structure design is reasonable and good then dehydrated significance for natural gas will reflect the efficiency maximization. Therefore, the tower design directly affects the use of energy and natural gas dehydration rate of energy, the two are complementary to each other.
