Embodiment Construction

[0058] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0059] In related technologies, a natural gas treatment system may be used to process natural gas produced from a natural gas well, so as to remove impurities in the original natural gas. The natural gas processing system may include: a throttling device, a heating device, a separation device, a drying device and a pressure boosting device. In the process of natural gas processing, a throttling device can be used to throttle the raw natural gas extracted from the natural gas well, so as to reduce the pressure of the natural gas, so as to ensure the safe transportation of the natural gas. Since pressure reduction will lead to temperature reduction, in order to avoid pipeline ice blockage during the natural gas transmission process...

Abstract

The invention discloses a natural gas treatment system, a control method thereof and a natural gas transmission system, and relates to the field of natural gas treatment. The natural gas treatment system comprises a natural gas treatment system body (00); a separation device (02), a drying device (03) and a pressure regulating transmission device (04) which are included in the natural gas treatment system body (00) can be integrated in a skid-mounted shell (01) and do not need to be fixed to the ground through a concrete foundation, and pipelines for connecting all the devices are also located in the skid-mounted shell (01); and the skid-mounted shell (01) can be conveniently moved, so that the natural gas treatment system provided by the invention is relatively good in mobility, relatively low in moving cost, relatively short in moving period and relatively small in occupied area. Due to the fact that the working states of all the devices integrated in the skid-mounted shell (01) can be controlled through a control device (05), manual control is not needed, and the automation degree of the natural gas transmission system is high.

Description

technical field [0001] The present application relates to the field of natural gas processing, in particular to a natural gas processing system, a control method thereof, and a natural gas transmission system. Background technique [0002] At present, a natural gas treatment system is generally used to process raw natural gas produced from natural gas wells (such as marginal gas wells), so as to remove impurities in the raw natural gas produced from natural gas wells. [0003] In related technologies, the natural gas processing system may include: a separation device, a drying device and other devices. Each independently installed device needs to be installed on the ground through a concrete foundation, and needs to be connected through buried pipes. [0004] After the natural gas production in a certain natural gas well is completed, the natural gas processing system connected with the natural gas well needs to be transferred to another natural gas well, so as to process t...
