The Public Boycott Of PX Aroused Great Concern Of The Whole Society.

< p > as one of the most typical products in the chemical industry, PX has attracted the attention of the whole society due to successive public boycott incidents. < /p >
On the one hand, on the one hand, PX's scientific and cognitive problems such as safety, environmental protection, planning distance and process safety are perplexing the ordinary people in the petrochemical area, spreading to the society, government, media and chemical industry. In the face of "PX demonization", public opinion urgently needs to popularize scientific, comprehensive and objective public awareness to help realize the harmony and stability between the local governments, communities and residents. On the other hand, PX, as an important organic chemical raw material, has a wide range of uses in industrial production, textile and clothing, fine chemical industry and other fields. Due to the rapid development of the downstream, the shortage of PX supply is becoming more and more serious, and the dependence on imports is getting closer to 50%. The contradiction between the development of PX industry and the rapid expansion of downstream industries is increasing. < /p >
< p > the reality is that the current external difficulties of PX need to be solved, but the chemical fiber industry has frequent actions. First, Heng Yi Petrochemical went to Brunei to invest in PMB petrochemical project. After that, Rongsheng Petrochemical invested overseas in Canada energy company. And market rumors already have private enterprises to get the road of domestic PX construction, but insiders say that when PX becomes a "street mouse", the relevant enterprises will not act reckless. < /p >
< p > < strong > < a > href= > http://www.91se91.com/news/index_c.asp > chemical fiber industry > /a > what is the status quo? < /strong > /p >
< p > 2013, the total output of chemical fiber in China is as high as 41 million 210 thousand tons, which accounts for more than 70% of the world's total. Especially polyester polyester fiber has developed rapidly in recent years, producing 33 million 400 thousand tons, accounting for 81% of the total output of chemical fiber, accounting for 75% of the world's polyester production, and becoming the largest and most dynamic production country in the world. However, due to various reasons, the growth of petrochemical raw materials industry, including PX and EG, is lagging behind, which seriously restricts the sound and sustainable development of polyester fiber industry. < /p >
< p > 2013, imports of chemical fiber raw materials 24 million 620 thousand tons, of which only polyester PX, EG, PTA total amounted to 20 million 270 thousand tons, especially PX imports soared, up to 9 million 80 thousand tons, dependence 53%. With the rapid development of China's polyester industry and PTA industry, China's demand for PX has increased rapidly, driving the rapid development of PX industry. < /p >
< p > by 2010, the capacity of PX has reached 8 million 360 thousand tons. China has become the world's largest producer and consumer of PX. In 2012, the capacity was 9 million 60 thousand tons, accounting for 24% of the world's total. In the same year, the output of PX was 7 million 750 thousand tons; the import PX630 million tons, and the dependency ratio was 45%; in 2013, the PX production capacity was 9 million 500 thousand tons and the output was about 8 million tons; the import PX908 million tons, and the dependency ratio was 53%. < /p >
< p > according to the planning and practice, the chemical fiber capacity in 2015 is 4600, the output is 4300 polyester 3500, the polyester capacity is 4100, the output is 3850, and the total volume of PTA is about 33 million 100 thousand tons; if it is all made in China, it needs PX about 22 million tons; if the 1 million 500 thousand ton PTA is imported, it still needs about 21 million tons of PX. With the continuous operation of polyester and PTA projects, the gap in 2015 is expected to reach 12 million ~1300 million tons.

< p > Why did the PX project choose Xiamen, Dalian, Ningbo and Kunming? Generally speaking, the location principle of PX project follows the upstream refinery enterprise, near the downstream PTA production enterprise, near the big river and the sea, near the international crude oil pipeline. < /p >
< p > in the distance between location and city, from the location of foreign PX projects, the distance from the city is not a controlling factor. Strictly implementing EIA and safety assessment is the most important. For example, the PX device in Busan, Korea is 4 kilometers away from the urban area, while the PX installation in Yokohama, Japan is only one way away from the residential area. < /p >
< p > PX main characteristics of pollutants such as hydrogen sulfide, ammonia, benzene, xylene, etc., the normal production process can affect the surrounding environment to meet the relevant national standard requirements. The ambient air quality of the main residential areas within a 5 km surrounding area of a large petrochemical enterprise with PX installations was monitored daily. The main results were: < /p >
< p > the main pollutant concentrations of PX devices such as H2S, ammonia, benzene, xylene, total hydrocarbon and benzo [a] pyrene are all in line with the requirements of "Hygienic standard for industrial enterprises design" (TJ 36-79) and "ambient air quality standard" (GB 3095-1996); the monitoring concentration values of conventional pollutants such as SO2 and NO2 are also not exceeding the standard; M10 has varying degrees of exceeding the standard, and the exceeding standard rate is 28.6% to 85.7%. < /p >
< p > the relevant laws have strict "Three Simultaneity" requirements for the safety, environmental protection and occupational health design of petrochemical projects. They are designed, constructed and put into operation at the same time. In the process design, equipment manufacturing, installation and construction, production, operation and maintenance, a series of standard standards have been drawn up, basically equivalent to adopting international standards. From the analysis of PX production safety and environmental risk prevention and control, the four units of aromatics fractionation, adsorption separation, isomerization and disproportionation are generally called PX devices. By comparing the dangers of PX and gasoline in common life, the danger of PX is slightly lower than that of gasoline, and PX and gasoline belong to low toxic substances. < /p >
