Abstract
Due to water is contained in the natural gas, also some other substance can form into hydrate in some special conditions. Above zero degree natural gas is a solid-state unstable compound. It can not only bring about the blockage of the pipe, but also cause the blockage of the spray nozzle and the separation equipment. So we use method of absorption to dehydrate. In this method we use triethylene glycol (TEG) as a sorbent. Because the TEG has a strong dehydrated capability of natural gas, and also TEG is quiet stable under high temperature, so TEG can not be solidified, at the same time TEG is easy to be regenerated. During the process of carrying, the losing amount of TEG is acceptable, and the dew point is high. All the property decide the TEG is suit for dehydrate. The absorbtion tower have many advantages. First, it is easy made and investment is low and pressure can be maintained long enough so that it can save power. Second, it can be used continuously. Third, the volume of tower is easy to be expanded. forth, the equipment of the tower is easy to be assembled so that it can lower the complexity of construction. Finally, it is convenient to avoid the pollution of solid adsorbent. In this method, the working theory of the dehydration tower is briefly stated. The paper not only make an reasonable choose of the parts of absorbtion tower, but also check the stress on the body of the absorbtion tower. What’s more, the way to reinforce the holes of the tower and technical demands of the tower are also explained in the paper.
