1, different components
The main component of gas is alkane, of which methane accounts for the vast majority, and there are a small amount of ethane, propane and butane, and generally also contains hydrogen sulfide, carbon dioxide, nitrogen and moisture, and trace amounts inert gases such as helium and argon.
The main components of natural gas are alkanes, of which methane accounts for the vast majority, and there are a small amount of ethane, propane and butane, in addition to hydrogen sulfide, carbon dioxide, nitrogen and water, and a small amount of carbon monoxide and traces of rare gases such as helium. and Argon etc. Before the natural gas is delivered to the end user, mercaptans, tetrahydrothiophene, etc. are used to add an odor to the natural gas to aid in leak detection.
2, different properties
Gas is a colorless, odorless, odorless gas, but sometimes you can smell an apple-like fragrance, which is due to the fact that the aromatic hydrocarbon gas is gushing out at the same time as the gas. The relative density of gas to air is 0.554, and the density of gas in standard state is 0.716kg.
Natural gas is a general term for mixed gas with hydrocarbon as the main body existing in underground rock reservoirs, with a specific gravity of about 0.65, which is lighter than air, and has the characteristics of colorless, odorless and non-toxic.
3. Different uses
Gas detectors are divided into industrial gas alarms and gas gas alarms. According to their own forms, they can be divided into fixed gas detectors and portable gas detectors. The alarm device uses a semiconductor ceramic gas sensitive device and a microcontroller as the control core of the alarm device. The device has moderate sensitivity, good response and recovery characteristics, and fast initial recovery characteristics.
Natural gas has a wide range of uses, mainly replacing coal with natural gas, which is used for factory heating, production boilers and thermal power plant gas turbine boilers.Natural gas power generation is an effective way to alleviate energy shortage, reduce the proportion of coal-fired power generation, and reduce environmental pollution. In terms of economic benefits, natural gas power generation requires less investment per unit of installed capacity, short construction period, and low on-grid electricity price. Competitiveness.
4, gas detection
The gas detector can be used in the environment to detect the leakage of gas and natural gas in the environment, the fixed gas detector can be used to monitor the gas leakage in the field environment in real time online, and the portable gas detector can be used can easily move the place that needs to be detected.
