Problems solved by technology

[0002] At present, most of the natural gas produced in the oil field is sent to the oil and gas treatment plant for processing through the gathering pipeline. The unpurified natural gas is usually called wet gas, which contains a large amount of water (H 2 O) and carbon dioxide (CO 2 ), transporting unpurified wet gas will cause serious corrosion to the gathering and transportation pipelines. At the same time, if the wet gas is not treated, it will be inconvenient to burn and use nearby. In the field of oil and gas gathering and transportation natural gas separation technology in the petroleum industry , the separation of natural gas generally adopts the method of gravity separation. Due to the small diameter of the liquid droplets, the dehydration and separation of natural gas is not complete. In addition, the conventional gravity separation has a large area of ​​equipment, large construction investment, and many operating points, which is not easy to manage and efficient. Low and other issues

Abstract

The invention discloses a supergravity dewatering device for natural gas, comprising a bottom frame, wherein a first tank used for flash evaporation of natural gas containing water is arranged on the upside of the bottom frame; a second tank used for buffering the natural gas containing water is arranged on the upside of one end of the first tank through an upper frame; a spray catcher used for getting rid of water contained in the natural gas for the second time is arranged at the upper side of the other end of the first tank, and a liquid discharging pipe used for discharging liquid inside the first tank is arranged at the lower side thereof; the first tank and the second tank are interconnected through a plurality of gravity separator tubes; and a silk screen is arranged inside the spray catcher, and a filling device is arranged between the spray catcher and the separator tubes inside the first tank. The supergravity dewatering device for natural gas has the advantages of safe and reliable running, low running cost, capability of separating liquid drops having radius of 10 micrometers, less operation points, easy management and usage, large processing quantity, low occupation area, low production cost and easy popularization.

Description

technical field [0001] The invention belongs to the technical field of petroleum gas treatment and processing, and in particular relates to a natural gas supergravity dehydration equipment for separating natural gas and performing preliminary dehydration on natural gas.
