Abstract

The invention discloses a throttling on-line natural gas light dydrocarbon separating device, and belongs to the technical field of recycling hydrocarbon compounds from natural gas. The throttling on-line natural gas light dydrocarbon separating device comprises a plurality of light dydrocarbon separating pieces and a light dydrocarbon collecting device for collecting separated light dydrocarbon, wherein the light dydrocarbon separating pieces are of plate-shaped structures and are respectively vertically arranged on the inner wall of a natural gas pipeline at equal intervals, the shapes of the side surfaces of the light dydrocarbon separating pieces are matched with the shape of the inner wall of the natural gas pipeline, the side surfaces of the light dydrocarbon separating pieces and the inner wall of the natural gas pipeline are in surface contact, the middle parts of the light dydrocarbon separating pieces are provided with through holes, light dydrocarbon is separated out when natural gas passes through the light dydrocarbon separating pieces to separate and then is collected on the inner wall of the natural gas pipeline, and the light dydrocarbon collecting device is arranged on the natural gas pipeline. The throttling on-line natural gas light dydrocarbon separating device provided by the invention continuously utilizes the pressure of the natural gas in the long-distance natural gas pipeline to separate out light dydrocarbon from the natural gas, the equipment cost of the light dydrocarbon separating device is reduced, additional power is provided, the operation cost is further reduced, and the separating device has an energy-saving property and an environmental-friendly property.

Description

technical field [0001] The invention relates to a device in the technical field of recovering hydrocarbon compounds from natural gas, in particular to a throttling type natural gas on-line light hydrocarbon separation device. Background technique [0002] With the commissioning of the second line of the West-East Gas Pipeline, my country has initially formed a natural gas pipeline network. According to the plan, in 2014, the West Third Line will run through the whole line, and then it will be connected with the main pipeline networks such as the West First Line, the West Second Line, the Shaanxi-Beijing First and Second Line, and the Sichuan-East Gas Transmission Line. . [0003] The data shows that the light hydrocarbon content in natural gas in the middle section of the Second West-East Gas Pipeline in my country is not less than 3.8% (mol fraction). With the vigorous development of my country's long-distance natural gas pipeline network, the separation technology of lig...
