Embodiment 1

[0020] In order to overcome the problems of many process blocks in the existing gas gathering station, long construction period, difficult organization and coordination, high investment cost, and large floor area, this embodiment provides a method such as figure 1 In the integrated integrated device for collecting sulfur-containing natural gas, the inlet 1 of the integrated device is connected to the natural gas separator 2, and the natural gas separator 2 is provided with a gas phase output port, an air discharge interface and a sewage discharge interface. The air discharge interface Connect the first venting device 26, the sewage discharge port is connected to the first sewage discharge device 3, the gas phase output port is connected to the first port 5, the first port 5 is connected to the external dehydration device, and the gas outlet of the external dehydration device is connected to the second port 6, the The second interface 6 is connected to the pipeline in three ways...

Embodiment 2

[0029] On the basis of Embodiment 1, the inlet of the flash liquid separator tank 20 is also connected to the first sewage interface 4, and the first sewage interface 4 is connected to the external sewage pipeline; the inlet of the flash liquid separator tank 20 is also connected to There is a venting pipeline interface 25, which is connected to the external venting pipeline; in this way, the device of the present invention can perform flash liquid separation treatment on the sewage transported by the external sewage pipeline and the natural gas transported by the external venting pipeline, saving costs .

[0030] The natural gas separator 2 is equipped with a pressure gauge, a liquid level gauge and an alarm; the first sewage discharge device 3 is provided with a blowdown valve, and the blowdown valve is electrically connected to the liquid level gauge on the natural gas separator 2 . The sewage liquid level of the first sewage discharge device 3 and the natural gas separator...

Abstract

The present invention provides an integrated integrated device for collecting sulfur-containing natural gas, comprising an inlet of the integrated device, a natural gas separator, a first venting device, a first sewage discharge device, a first interface, a second interface, a natural gas filter, Natural gas pressure regulating device, first natural gas meter, first natural gas outlet port, throttling device, second natural gas meter, cut-off device, second natural gas outlet port, third venting device, second venting device, third venting device connection, remote ignition device, third natural gas outlet connection, flash separator tank, fourth venting device, fourth natural gas outlet connection, second sewage discharge device and second sewage connection. The device replaces the production separator area module, flash liquid separation tank area module, metering output area module, and self-use gas area module in the existing gas gathering station. It has a compact structure, reduces floor space, is convenient for transportation, and saves investment costs. .

Description

technical field [0001] The invention relates to an integrated integrated device, in particular to an integrated integrated device for collecting sulfur-containing natural gas. Background technique [0002] With the development of the national economy, the demand for energy is increasing. As a clean energy, natural gas is developing rapidly. As the surface construction part of natural gas development, the construction scale is large, and a large number of gas gathering stations are built every year. [0003] Gathering stations play an important role in the gathering and transportation of gas fields. First, they receive gas from the well site, which is heated, throttled, separated, dehydrated, and metered before being transported to the treatment plant. (purification plant). The gas-gathering station has the functions of heating, throttling, separation, dehydration, metering, pigging, etc. At the same time, it provides fuel gas for generators in the gas-gathering station and...
