In recent years, with the rapid development of China's economy, the instrumentation industry has also developed rapidly, since 2004 production and sales exceeded the 100 billion yuan mark for the first time, the development of the industry has entered the fast lane, and the total output value of the industry exceeded 200 billion yuan in 2006; In 2007, the total output value of the instrumentation industry reached 307.8 billion yuan, with a growth rate of 28.5%; According to the statistics of the Instrumentation Industry Association, the total output value of the instrumentation industry in the first half of 08 reached 175.59 billion yuan, a year-on-year increase of 23.8%, of which the growth rate of analytical instruments and environmental monitoring instruments was as high as 32%.
The progress of science and technology provides conditions for the development of the gas detector instrument industry, the promotion of market and government policies, the improvement of people's safety awareness, and the improvement of relevant regulations and laws are the core driving force for the development of the gas detector instrument industry, which makes the gas detector instrument industry in a period of rapid industrial growth.
From the perspective of technological development, according to the different principles of using sensors, common gas detectors have their own applicable gases and application fields, and new technologies and new products are becoming the mainstream of gas detectors and meters in the future.
In the future, gas detectors using semiconductors and catalytic principles will still occupy some low-end markets by relying on price advantages. Electrochemical sensors and detection instruments have outstanding comprehensive advantages in the field of low-concentration toxic gas, organic vapor, alcohol gas, and oxygen monitoring with high accuracy requirements. Infrared gas sensors and instruments are suitable for monitoring all kinds of flammable, explosive, and carbon dioxide gases, and have significant advantages such as high accuracy, good selectivity, high reliability, non-poisoning, non-dependence on oxygen, less environmental interference factors, and long life. These advantages will lead to electrochemical and infrared gas detectors occupying a wider range of high-end market in the industry, and gradually becoming the mainstream market in the future. According to incomplete forecast statistics, in the next few years, the annual demand for infraredgas detectors in various industries in China will reach 1.7 million units (sets), and the market capacity will be about 6.8 billion yuan; The demand for gas detectors using the principle of electrochemical will reach 4 million units (sets), with a market capacity of about 5.6 billion yuan, with broad prospects and rapid growth.
At present, China's economy is in a period of rapid growth, and the country attaches great importance to safety and environmental protection, and relevant policies and regulations have been introduced one after another, which has greatly stimulated the rapid expansion of the market capacity of the gas instrumentation industry.
1) Gas industry
China has built natural gas transmission trunk lines, including the West-East Gas Transmission, the Shaanxi-Beijing Second Line, the Zhongwu Line, the Shininglan Line and the Hebei-Ningxia Liaison Line. During the 11th Five-Year Plan period, it is necessary to gradually improve the national oil and gas pipeline network, and build a second west-to-east gas pipeline and a land import oil and gas pipeline in a timely manner. China also plans to double its share of natural gas in its energy consumption mix by 2010 to reduce its dependence on coal. According to the plan released by the National Development and Reform Commission, natural gas accounted for 2.8% of China's total energy consumption in 2005, and natural gas accounted for 5.3% of China's total energy consumption in 2010. Therefore, the state has increased the exploitation and exploration of gas fields, and with it, more and more domestic gas fields have been put into production. According to the "Eleventh Five-Year Plan for Energy Development" published on the website of the National Development and Reform Commission, the target of natural gas production in 2010 will reach 92 billion cubic meters, an increase of more than 50% over 07 production. A large number of natural gas field development and pipeline construction will greatly increase the demand for natural gas detection equipment, and high-performance infrared gas detector instruments have obtained a rare development opportunity. In the process of gas mining, processing, transportation and use, the demand for Flammable gas detectors will reach hundreds of thousands of units.
2) Petroleum and petrochemical
From the perspective of China's industrial development, during the "Eleventh Five-Year Plan" period, China's petroleum and chemical industries will follow the direction of baseization, large-scale and integration, optimize the development of basic chemical raw materials, actively develop fine chemicals, and eliminate high-polluting chemical enterprises. It is understood that the state will build several 10 million tons of oil refining enterprises and million-ton ethylene refining and chemical integration bases in areas with abundant resources and strong market demand, forming an internationally competitive refining and chemical enterprise group such as the Bohai Bay, Hangzhou Bay, and the Pearl River Delta. The first batch of four national oil reserve bases will be built: Ningbo Zhenhai, Zhejiang Zhoushan, Shandong Qingdao and Liaoning Province, with a total capacity of 16 million cubic meters. Within three years, about 20 crude oil processing bases of 10 million tons will be gradually formed.
In 2008, China will start the construction of three major oil refining projects in advance, namely: PetroChina Guangxi oil refining, with a total investment of more than 10 billion yuan and an annual processing of 10 million tons of crude oil; Sinopec Qingdao large-scale oil refining, with a total investment of about 12.5 billion yuan and an annual refining capacity of 10 million tons; CNOOC Huizhou Refinery; The infrastructure investment is about RMB 19.3 billion, and the annual processing capacity is 12 million tons. The state will also adopt a park-based model to develop the ethylene industry. In the near future, seven major ethylene projects will be launched, and the ethylene production capacity is expected to reach 5.83 million tons in 2010. These large-scale petroleum and petrochemical projects that have been built or planned in the near future will make extensive use of related gas detectors, especially high-performance and more advantageous infrared optical gas detectors.
While the demand for domestic petroleum and petrochemical products continues to grow steadily, more and higher requirements will also be put forward for the quality and variety of petroleum and petrochemical products. The main elements that make up crude oil are carbon, hydrogen, sulfur, nitrogen and oxygen, and compounds containing sulfur, oxygen and nitrogen are harmful to petroleum products and need to be removed as much as possible in oil processing. This causes a large amount of toxic gases such as carbon monoxide, sulfur dioxide, hydrogen sulfide and organic vapors such as benzene, aldehyde and ketones to be produced during the production and processing process, posing a threat to production safety and environmental protection. At present, the method of gas detection and analysis is generally used for control, and the gas detector table is also used for the leakage detection of flammable gas and the monitoring of environmental gases such as hydrogen and oxygen in oil production. It is estimated that the average gas detector equipment per 10,000 tons of refined oil production requires about 40 sets (sets), including 20 sets of flammable gas, based on the current annual output of 220 million tons of refined oil, the annual demand for gas detectors is about 880,000 units (sets), of which about 440,000 units (sets) of Flammable gas detectors and about 220,000 sets of toxic gas detectors. 220,000 sets of other organic steam and gas analysis equipment. In various oil and gas stations, there is also a large demand for gas detectors for the detection of toxic gases such as flammable gas, carbon monoxide, sulfur dioxide, hydrogen sulfide, and organic vapors such as benzene, aldehydes, and ketones, which are mainly used for safety protection and prevent poisoning and explosion accidents, and each oil and gas station needs about 7.2 sets of gas detectors and instruments on average. In 2007, the total number of domestic gas stations has exceeded 100,000, so the annual demand for Flammable gas detectors is about 720,000 units (sets). Based on the above data, each set of gas detector instruments is calculated and analyzed at 2500 yuan, and the current market capacity of gas detectors and instruments in the entire petroleum and petrochemical industry is about 4 billion.
3) Chemical industry
With the increasing shortage of oil resources, coal-fired work is the focus of China's medium and long-term energy development strategy, and will occupy an important position in the future long-term development. China plans to invest more than 1 trillion yuan to vigorously develop the coal chemical industry, and plans to build seven major coal chemical industry zones in the country, namely the middle and lower reaches of the Yellow River, Mengdong, Heidong, Sulu, Henan, Central Plains, Yunnan, Guizhou and Xinjiang. At the same time, the transformation of chemical enterprises to coal chemical industry has become a trend, and Shuanghuan Technology, Lutianhua, Yuntianhua, Liuhua Co., Ltd., and Hubei Yihua have set foot in coal enterprises to prepare for the transfer to coal chemical industry.
In the industrial route, whether it is coking industry, coal gasification-synthetic ammonia, coal-based methanol, coal-to-synthetic oil, coal chemical co-production, there is a wide demand for gas alarm products, especially for sulfur dioxide, hydrogen sulfide, carbon monoxide, chlorine, ammonia and other gas sensors are very large, preliminary calculations, an average of about 22 gas sensors per 10,000 tons of coke production, including 10 flammable gas (sets), 12 units (sets) of toxic gases; Based on the current annual output of 260 million tons of coke, 260,000 Flammable gas detectors (sets) are needed, and more than 312,000 units (sets) of toxic gas detectors are needed, with a total annual demand of about 572,000 units (sets), and the current market capacity of gas detectors in the entire coal chemical industry will reach 1.144 billion yuan.
Large chemical manufacturing industrial parks such as fine chemicals, biochemicals, special chemicals, and agrochemicals also have extensive demand for gas detectors. In the newly promulgated "Catalogue of Safety Facilities for Hazardous Chemical Construction Items", it is clearly stipulated that "alarm facilities such as pressure, temperature, liquid level, flow, components, flammable gas, toxic and harmful gases, oxygen and other detection and alarm facilities must be installed." "At present, there are more than 60 chemical parks under construction in China. Relying on the Yangtze River system, the Yangtze River Economic Belt and the Yangtze River Delta region have formed chemical parks such as Sichuan Western Chemical City, Suzhou Industrial Park, and Shanghai Chemical Industry Park; Relying on the Pearl River Economic Belt and the Pan-Pearl River Delta region of the Pearl River system, chemical industrial parks such as Maoming, Huizhou and Zhuhai have been formed. In the above-mentioned chemical industrial park alone, there are more than 7,300 chemical enterprises stationed in total, covering basic chemical raw materials and synthetic materials, chemical raw materials and chemical product manufacturing, pesticides, special chemicals and rubber products, etc., and the demand for gas detection products is all-round, covering almost all gas types, among which organic steam, combustible others, sulfur and nitrogen toxic gas detection products are the most. With the continuous strictness of the General Administration of Safety and Quarantine on the safety requirements of chemical and hazardous chemical processing, the use of gas detectors and instruments in the field of chemical and hazardous chemical processing has also increased year by year, and the annual market capacity is about 300,000 units (sets), including about 227,000 units (sets) of flammable gas, and about 73,000 units (sets) of organic steam and toxic gas. According to the calculation of 2,000 yuan per set of products, there will be a market size of more than 600 million yuan.
4) Metallurgical industry
The metallurgical industry uses the most and most widely used gas detection, mainly in steel and aluminum production. China is the world's largest steel producer. During the period from 2006 to 2010, China's steel production capacity will increase by 240 million tons, which is basically equivalent to the 260 million tons of production capacity increased during the "Tenth Five-Year Plan" period, and the scale of enterprise production capacity will grow rapidly. In 2007, there were 122 enterprises with a million tons of production capacity in China, and 13 enterprises with a 10 million ton capacity, namely Anben Group, Baosteel, Xintang Steel, Wuhan Iron and Steel, Ma Iron and Steel, Shagang, Shougang, Jigang, Laigang, Valin Group, Baotou Steel, Taigang and Anyang Iron and Steel, of which Anben Group had a production capacity of 28 million tons, Baosteel Group reached 27.5 million tons (excluding Bayi 5 million tons), New Tang Steel 26 million tons, and Wuhan Iron and Steel 18 million tons (excluding Liugang 6 million tons).
According to the current trend of domestic enterprises under construction and mergers and acquisitions, by 2010, there will be 6 enterprises with a scale of more than 20 million tons, of which Anben Group and Baosteel Group will have a production capacity of more than 40 million tons, the scale of New Tang Steel Group will exceed 30 million tons, and the scale of Shougang Group, Shandong Iron and Steel Group and Wuhan Iron and Steel Group will also be more than 25 million tons. At the same time, there will be new tens of millions of tons of enterprises in the future. In short, before 2010, China's iron and steel industry is still in a period of scale expansion, and after 2010, the development direction of China's iron and steel industry will expand by orders of magnitude
