Description

Technical Field

[0001] The invention relates to the technical field of natural gas detection and analysis, and in particular to a natural gas trace adamantane analysis device and an analysis method. Background Art

[0002] Natural gas is a clean, low-carbon fossil energy source and one of the most important natural resources in human society. It will play an important role in the global energy green and low-carbon transformation. As the world transitions from coal to less polluting energy sources and tries to minimize the impact of global climate change, natural gas is a key fossil fuel. The main use of natural gas is as a fuel. It can be used to make carbon black, chemicals and liquefied petroleum gas. Propane and butane produced from natural gas are important raw materials for modern industry. Natural gas is stored in underground porous rock formations, including oilfield gas, gasfield gas, coalbed methane, mud volcano gas and biogenic gas, and a small amount is also found in coal seams. Natural gas contains many different compounds. The largest component of natural gas is methane, which accounts for more than 70% of the concentration of typical natural gas, followed by ethane, propane, butane and pentane. In addition, natural gas also contains a small amount of C6+-C14+ light hydrocarbons and non-hydrocarbon gases, such as carbon dioxide, nitrogen, hydrogen, carbon monoxide and water vapor.

[0003] Commercial natural gas reservoirs are formed by biogenic and thermogenic processes. 80% of the gas reservoirs discovered in the world are thermogenic. The main component of natural gas reservoirs is CH4, among which highly mature thermogenic natural gas often contains trace amounts of adamantane compounds. These compounds contain rich geochemical information and are of great significance for identifying the source and origin of weather and studying the migration, accumulation and preservation of natural gas. Since the content of adamantane in natural gas is very trace, its analysis is quite difficult.

[0004] At present, the existing analysis of trace diamond in natural gas requires the use of more equipment for sampling and analysis, the equipment cost is high, and the operation is cumbersome and time-consuming. Therefore, a natural gas trace diamond analysis device and analysis method are proposed to solve the above problems. Summary of the invention

[0045] Furthermore, in order to detect and analyze the trace light hydrocarbon adamantane in the liquid natural gas formed after condensation, the liquid natural gas is detected and analyzed by the analysis mechanism 3, which includes a detection analyzer 301 and a placement plate 302.

[0046] Furthermore, in order to introduce natural gas into the jet mechanism 2, the delivery pipeline 6 is connected to the air intake pipe 201 to achieve the purpose of natural gas delivery.

The filtered liquid droplets fall on the inner bottom of the body 1, so as to avoid the influence of a large amount of liquid impurities in the natural gas after condensation on the detection and analysis data of trace light hydrocarbon adamantane in the natural gas. By arranging a conical bucket 9 inside the body 1, the conical bucket 9 is located between the condenser 8 and the filtering mechanism 4, so that the liquid passing through the condenser 8 is concentrated on the conical bucket 9 and falls onto the filter plate 402 on the filtering mechanism 4, thereby facilitating the filtering of the condensed liquid.

[0051] like Fig. 9 , 10 As shown, in order to facilitate the removal of the filter plate 402 on the filter mechanism 4 for cleaning impurities, a side frame 404 is fixedly installed on the right wall of the filter frame 401, a pull rod 405 is arranged on the side frame 404, a block 408 is fixedly installed on the left end of the pull rod 405, a return spring 407 is sleeved on the pull rod 405, and a handle 406 is fixedly installed on the right end of the pull rod 405.

Example 3

[0052] like Figure 1-10 As shown, based on Example 1, the present invention provides an analysis method for a natural gas trace adamantane analysis device, comprising the following steps:

[0053] S1.

The servo motor 207 is started to drive the gear 209 so that the gear ring 206 drives the gas disc 204 to rotate, so that the natural gas can fully contact with the condenser 8, thereby improving the efficiency of natural gas condensation. By arranging a filtering mechanism 4 inside the body 1, the liquid droplets of the natural gas after liquefaction through the condenser 8 are filtered through the filter plate 402 on the filtering mechanism 4, and the impurities in the liquid droplets are intercepted and filtered. The filtered liquid droplets fall on the bottom of the body 1, thereby preventing the liquid impurities in the natural gas from being condensed. In order to improve the detection and analysis data of trace light hydrocarbon adamantane in natural gas, a conical bucket 9 is arranged inside the body 1, and the conical bucket 9 is located between the condenser 8 and the filter mechanism 4, so that the liquid passing through the condenser 8 is concentrated on the conical bucket 9 and falls onto the filter plate 402 on the filter mechanism 4, thereby facilitating the filtering of the condensed liquid. The condensed and filtered liquid is accumulated at the lower part of the body 1, and the delivery pump 303 is started to sample the liquid through the sampling tube 305 and deliver it to the detection analyzer 301 for detection and analysis, thereby realizing the integration of sampling and analysis, reducing the equipment cost and cumbersome steps, and improving the sampling and analysis efficiency of trace light hydrocarbon adamantane in natural gas.
