From the perspective of my country's industrial development, during the "Eleventh Five-Year Plan" period, my country's petroleum and chemical industries will follow the direction of base, large-scale and integrated, optimize the development of basic chemical raw materials, actively develop fine chemicals, and eliminate high-polluting chemical enterprises. It is understood that the country will build several 10 million-ton oil refining enterprises and 1 million-ton ethylene refining and chemical integration bases in regions with abundant resources and strong market demand, forming an international competition in the Bohai Bay, Hangzhou Bay, and Pearl River Delta. Powerful refining and chemical enterprise group. The first batch of four major oil reserve bases will be built: Ningbo Zhenhai, Zhejiang Zhoushan, Shandong Qingdao and Liaoning Dalian. The total capacity of the four oil reserve bases will reach 16 million cubic meters. Within three years, about 20 crude oil processing bases of ten million tons will be gradually formed.
In 2008, China will start the construction of three major oil refining projects in advance, namely: PetroChina Guangxi Refinery, with a total investment of over 10 billion yuan and an annual processing capacity of 10 million tons of crude oil; Sinopec Qingdao Refinery, with a total investment of about 12.5 billion yuan, annual oil refining Capacity of 10 million tons; CNOOC Huizhou Refinery; infrastructure investment of about 19.3 billion yuan, with an annual processing capacity of 12 million tons. The country will also adopt the park mode to develop the ethylene industry. In the near future, seven major ethylene projects will be launched, and the ethylene production capacity in 2010 is expected to reach 5.83 million tons. These large-scale petroleum and petrochemical projects that are under construction or planned in the near future will use a lot of related gas detection instruments, especially high-performance and more advantageous infrared optical gas detection instruments.
While the domestic demand for petroleum and petrochemical products maintains steady growth, more and higher requirements will 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 should be removed as much as possible in petroleum processing. This causes a large amount of toxic gases such as carbon monoxide, sulfur dioxide, and hydrogen sulfide, and organic vapors such as benzene, aldehydes, and ketones to be produced during production and processing, posing a threat to production safety and environmental protection. At present, the method of gas detection and analysis is generally used for control. In oil production, the leakage detection of combustible gases and the monitoring of environmental gases such as hydrogen and oxygen also require the use of gas detection instruments. It is estimated that every 10,000 tons of refined oil production requires about 40 sets (sets) of gas detection instruments, including 20 sets (sets) of combustible gas. Based on the current annual output of 220 million tons of refined oil, the annual demand for gas detection instruments and meters The volume is about 880,000 sets (sets), including about 440,000 sets (sets) of combustible gas detection instruments, about 220,000 sets (sets) of toxic gas detection instruments, and 220,000 sets (sets) of other organic vapor and gas analysis equipment. . In various oil and gas stations, there is also a large demand for gas detectors for the detection of flammable gases, carbon monoxide, sulfur dioxide, hydrogen sulfide and other toxic gases and organic vapors such as benzene, aldehydes, and ketones. They are mainly used for safety protection and prevent poisoning and explosion accidents. , On average, each oil and gas station needs about 7.2 sets (sets) of gas detection instruments. In 2007, the total number of domestic gas stations has exceeded 100,000, and the annual demand for combustible gas detection instruments in this regard is about 720,000 units (sets). Based on the above data, each set of gas detection instruments is calculated and analyzed at 2,500 yuan. At present, the market capacity of gas detection instruments in the entire petroleum and petrochemical industry is about 4 billion.
