Participant in the formulation of national standards for ecological environment: Chengtian Shiyou provides gas analyzers for multiple environmental monitoring stations

[ Star Enterprise of Chemical Machinery Equipment Network ] In 2001, Beijing Chengtian Shiyou Technology Co.
, Ltd.
(hereinafter referred to as "Chengtian Shiyou") was established in Beijing, starting a new journey of environmental monitoring
.
Eight thousand miles of road, cloud and moon, Chengtian Shiyou is a witness, participant and builder of China's ecological environment process.
It has participated in the formulation of many national standards for more than 20 years, and has opened a new situation in the changing situation
.

 

In 2021, the first year of China's "14th Five-Year Plan" ecological environment construction, the environmental quality will be significantly improved
.
The ratio of good days in cities at the prefecture level and above was 87.
5%, up 0.
5 percentage points year-on-year; PM2.
5 concentration was 30 micrograms/m3, down 9.
1% year-on-year; the carbon dioxide emission per unit of GDP met the "14th Five-Year Plan" schedule requirements; nitrogen The total emission reduction targets of 4 major pollutants including oxides, volatile organic compounds, chemical oxygen demand, and ammonia nitrogen have successfully completed the annual target
.

 

　　However, individual "old solid" problems still need to be cleared up
.
With the rapid development of modern industry and transportation, coal, petroleum and other fossil energy sources are widely used, urban pollutants have increased, and harmful gases such as sulfur dioxide, nitrogen oxides, and carbon monoxide are discharged in large quantities, and exhaust gas pollutants have caused PM2.
5 index in many cities high, threatening human health and disturbing the normal ecological environment system
.
Exhaust gas pollution has become one of the core issues in China's current ecological environment construction
.

 

　　How to control waste gas pollution and take the road of green, efficient and environmental protection? It also needs to be considered comprehensively, based on the clear standard, with the source of pollution as the core, and with environmental monitoring instrument companies as the probe, to form a model of "removing the source, controlling the loss in the middle"
.

 

　　Data for products: assisting the release of the "Standard", breaking the "empty layer" of the norm
 

　　On December 30, 2021, the Ministry of Ecology and Environment officially promulgated "Portable Fourier Transform Infrared Spectroscopy for the Determination of Gaseous Pollutants (SO2, NO, NO2, CO, CO2) from Stationary Pollution Sources" HJ1240-2021 (hereinafter referred to as the "Standard"), This standard is applicable to the determination of five gaseous pollutant concentrations of sulfur dioxide, nitrogen monoxide and nitrogen dioxide (collectively referred to as nitrogen oxides), carbon monoxide and carbon dioxide in the exhaust gas of stationary pollution sources by a portable Fourier transform infrared gas analyzer.
Determination of concentration of gaseous pollutants in exhaust gas
.

 

　　When the industry standard was formulated, there were very few brands in the domestic market that could be used for the monitoring of stationary source exhaust gaseous pollutants
.
As a first-line environmental monitoring instrument company and the general agent and after-sales service center of GASMET in Finland, Chengtian Shiyou has been put into the task since the "Standard" formulation requirements in 2009 were issued
.
Relying on the advantages of strong technical talents, Chengtian Shiyou arranges experienced engineers to participate in the preparation group experiment during each verification, providing a strong technical guarantee for the preparation group.
The experimental data becomes a reliable basis for the subsequent formulation of the "Standard"
.

 

　　It is worth mentioning that due to the early start of the drafting of this standard, only the Finnish Gasmet Dx4000 portable Fourier transform infrared gas analyzer provided by Chengtian Shiyou is available in the domestic market, which can be used for waste gas monitoring of fixed pollution sources.
Other brands appeared one after another
.
In the process of standard drafting, Chengtian Shiyou provided Finnish Gasmet Dx4000 technical support for the verification unit, and provided irreplaceable assistance for the acquisition of experimental data
.
Since 2010, 6 verification laboratories have used Gasmet Dx4000 portable Fourier transform infrared gas analyzers to carry out static tests of method characteristic indicators such as detection limit, precision and accuracy
.
Not only that, the standard compilation team also used the Gasmet Dx4000 portable Fourier transform infrared gas analyzer as a verification instrument to conduct on-site inspections on domestic waste incineration, sintering outlets in iron and steel plants, heating furnaces in petroleum refineries, power generation and other sewage discharge units, and obtained a large number of results.
Usability and necessity data
.

 

　　Prior to this, China had not fully controlled the emission of carbon dioxide indicators, and the current standards and norms rarely involved carbon dioxide emission standards
.
The release of the "Standard" marks that China's fixed pollution source waste gas and gaseous pollutants detailed rules and regulations have traces to follow, entering the era of comprehensive carbon dioxide emission supervision
.

 

　　"Settlement" of products: forming large-scale applications and taking the road of pollution prevention and control
 

　　The portable Fourier transform infrared gas analyzer is a new type of gas analyzer used for on-site monitoring and analysis of gaseous pollutants from fixed pollution sources
.
The analyzer adopts the method of constant temperature heating 180 ℃ from the sampling tube to the host sample room, which has the advantages of high temperature original sampling, non-destructive and rapid, high analysis accuracy, strong anti-interference ability, etc.
It is especially suitable for fixed pollution sources in waste gas with high humidity and low concentration The on-site monitoring of gaseous pollutants is a good supplement to the ultra-low emission monitoring technology system of fixed pollution sources in China
.

 

　　Today, technological innovation capability and product manufacturing capability are the "springboard" of the instrument industry
.
The measurement accuracy and precision of the Gasmet Dx4000 portable Fourier transform infrared gas analyzer give Chengtianxiu a full force to expand its market share
.
Good news keeps coming: Gasmet Dx4000, which has participated in the standard verification test throughout the process, has officially "settled" in multiple environmental monitoring stations, forming a large-scale application
.
High-quality products and reliable after-sales service create a brand sample effect, and Chengtian Shiyou has once again become the "sweet pastry" of many environmental monitoring sites, contributing to refined environmental governance and efficient ecological monitoring
.

 

　　At present, China's greenhouse gas emission reduction pressure is not small
.
In order to better promote carbon emission reduction and curb global warming, carbon emission rights trading and carbon emission reduction have been launched, and the establishment of carbon dioxide emission standard limits for major industries is expected
.
In this context, it is also necessary to base on accurate gas emission concentration measurement.
This requirement virtually contributes to the environmental monitoring instrument industry, and environmental monitoring instrument enterprises have broad prospects
.

 

　　Those with deep roots have luxuriant leaves, and those with deep roots have long flows
.
In 2022, the Ministry of Ecology and Environment will continue to promote the implementation of multiple ecological environment standards to ensure the steady construction of the ecosystem
.
Chengtian has a clear strategy of showing excellence, and will continue to take serving industry standards and building an efficient ecological environment monitoring system as its own responsibility, continue to optimize the layout of environmental monitoring instruments, strengthen the integration of production, education and research, and complete various monitoring tasks.
Continued efforts in research, fire emergency response, disease control and commodity inspection and other fields have become a backbone
.
