Abstract

The invention provides a high-efficiency atomized glycol dehydration device and its use method and application, belonging to the technical field of natural gas dehydration technology. The high-efficiency atomized glycol dehydration device is mainly composed of two parts: a glycol atomization unit, a gas-liquid contact and a separation unit. The device designed by the invention can make the contact between the raw material gas and the glycol more fully through the organic combination of the supergravity technology and the traditional triethylene glycol dehydration tower, improve the mass transfer effect, and better solve the problem that the original glycol dehydration equipment is bulky. Compared with the original dehydration equipment, it has the characteristics of low equipment height, small footprint, convenient maintenance and low production cost, and is more suitable for the treatment of offshore natural gas, so it has good practical application value. .

Description

technical field [0001] The invention belongs to the technical field of natural gas dehydration process, and in particular relates to a high-efficiency atomized glycol dehydration device and its use method and application. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] The natural gas produced at the wellhead often contains a large amount of water vapor. When the pipeline pressure and ambient temperature change, liquid water may be precipitated, and under certain conditions, solid hydrates will be formed with alkanes. The existence of these substances will reduce pipeline damage. The transmission capacity of natural gas will block valves and pipelines in severe cases. Wh...
