Insular dust overcomes the Singapore abundant corridor that satellitic map shows device of PX of factory of Sen Meifu refine, be apart from residential area to have 900 meters only. In addition, the space that device of world main PX occupies the city zone is not far also, the United States rests device of Si Dui PX is apart from the city zone device of Lu Tedan PX is apart from 1.2 kilometers, Holand device of PX of hill of boiler of 8 kilometers, Korea is apart from downtown downtown has two PX project inside industrial district of island of water of county of hill of ridge of 4 kilometers, Japan, be less than the distance between the 2 kilometers, PX factory that is located in plain Qi and residential area to be less than 5 kilometers only recently from living area.

This year in May, chinese oil is in 10 million Kunming is quiet tons / year the opposition that oil refining project suffers the people. Among them people reaction is the strongest, it is this refinery will produce PX.
This is not PX project first time suffers boycott. June 2007 Xiamen PX project, August 2011 Dalian PX project, and project of Ning Bo PX protested the come to a standstill in sound in the public in October 2012.
What is PX project after all? This sends the new material item that exhibit flourishingly in the whole world, does the predestined relationship where was China become " mice crossing a street " ? Let us open the mysterious veil of PX.
PX is what —— after all
According to international standard, PX does not calculate dangerous chemical, the coffee that drinks with us is congeneric " likelihood carcinogenic substance "
People objects PX project, talk about the prime cause that PX color changes even, it is to think PX project not only the pollution that creates an environmharrison hot spring weather forecastent, and PX itself still has the very strong sex that cause cancer, endanger the person's health badly.
Actually PX is done not have so " extraordinary " ! Once was engaged in the Lv Dapeng of spokesman of news of the petrifaction in currently holding the post ofof PX production for a long time explaining, PX is the abbreviate of Para-xylene, chinese formal name " to xylene " , the aromatic hydrocarbon apperception that is fragrance of a kind of colorless and liquid state existence, transparent, odour closes matter, taste rise a bit sweet even.
Basis " global chemical integrates classification and label system " and " dangerous chemical directory " , a lot of countries wait in the United States, Australia, PX does not calculate dangerous chemical. The data shows, no mati want modern dining chairster be data of sex of dangerous mark, healthy harm, poisonous a Confucian school of idealist philosophy of the Song and Ming Dynasties, calamity of on-the-job still course of study defends wait for a standard to fall, PX does not belong to product of tall danger tall poison. In the European Union, PX also is labelled only harmful article.
An industrial chemicals that looks gentle, why can we fear so? A main reason depends on PX medium " benzene " . According to international cancer research organization (IARC) maintain, benzene belongs to material of a kind of chemistry that cause cancer. The meaning of a kind of carcinogenic substance is, deliver cancerous sex testimony to the mankind sufficient.
But, IARC classifies the 3rd kind of medium —— to may cause cancer in 5 gradient truly to the cognizance of PX. The meaning that this orgnaization may cause cancer is the testimony that delivers cancerous sex to the mankind finite, deliver cancerous sexharrison hot spring public pool testimony to experimental animal and inadequate; Perhaps send inadequacy of cancerous sex evidence to the mankind, deliver cancerous sex testfree watch caseimony to experimental animal sufficient.
It is current that IARC causes sex of human cancer risk to evaluate to chemical material accepted definitive data. Interesting is, in its in detail of 5 kinds of carcinogenic substance, appeared awesomely 1991 " coffee " name, with us " of detest " PX is congeneric the 3rd kind.
Although lack human body to deliver the testimony of cancerous sex, but oil and Gu Zongqin of dean of chemical program courtyard also say frankly, this does not show PX is completely avirulent, its characteristic is 4 words, low poison is combustible. Concerned medicine data also shows, human body absorbs the PX of excessive, meeting cross-eye ministry and the upper respiratory tract cause stimulation. Contact PX for long, bring about possibly also have a headache, the symptom such as be agitated, depressed, insomnia, exhaustion, serious person, can create short-term memory obstacle. An experiment of the United States makes clear, PX will be right fetal cause certain effect, accordingly, expert proposal pregnant woman or lactation woman reduces osculatory PX as far as possible, should reduce a contact as far as possible like them alcohol, tobacco and other remedy are same.
Respecting low poison, tell us a such professional knowledge about the expert that studies noxiousness, academic upper bound decides the noxiousness of a kind of material, use half the number normally deadly dosage will describe. The experiment proves, the fatal dose of half of the tested animals of salt of bandicoot profess to convinced is 3000mg/kg, PX is 3523mg/kg, alcohol is 7060mg/kg. 3 person deadly dosage states half the number simply even if: Salt The PX that strict scientific test and authoritative orgnaization reach is the conclusion of small poisonous chemical matter, was not accepted by more Chinese peoples apparently. "As a result of a variety of misunderstanding, brought about many people watch case manufacturerto regard PX project as great scourges. " Chinese oil and Li Runsheng of vice-chairman of chemical Joint Industry Conference say.
PX can do what ——
PX solved natural fiber and commissariat to argue the issue of the ground, also be the requisite that improves benzine quality
However, PX project is not great scourges not only, and, cannot leave like modern society like benzine, we also cannot leave PX, it has made the one part that we live.
Li Runsheng says, regard fundamental chemical industry as the product, PX has become the essential element in current people life, in the basic necessities of life that blends in people to live daily. Many tons of 3000 PX that at present the whole world produces, the majority makes the raw material of polyester fiber. Many polyester fiber is become by treatment dress, satisfy the whole world not only the clad problem of 60 much population, still satisfied people to wait for more requirements to dress colour, burnish, drape, Bao Hou, diaphaneity.
norton internet antivirusIn a sense, PX solved natural fiber and commissariat to argue the issue of the ground. Our country is a population the country that resource of numerous, farmland shorts relatively. Every 10 thousand tons of synthetic fibre are equivalent to the natural spin fiber that place of 70 thousand mus of farmland produces about. 2012, our country produces synthetic fibre to make an appointment with 28 million tons. If produce the natural fiber of coequal amount, need farmland nearly 200 million mus.
PX is concerned with the dress of people not only, it also is the content that can enter the mouth directly, for instance medicaments capsule, PX is one of raw material. The main raw material of the packing material such as mineral water bottle, also be PX.
Of PX and people live close together also and relevant. It is the raw material of a lot of housing materials, also can produce paint dissolvent with a future life. As technical progress, the downstream product PET of PX, replacing aluminous, glass, pottery and porcelain and paper increasingly, application makes a trade at electric equipment electron, car and machinery.
China is entering car society, and the 5% right-and-left composition in benzine are PX. PX not only it is petrolic main component, also be to produce essential of high quality petrolic.
A lot of our country cities suffer the pain of PM2.5 now. Reduce one of important ways of urban mist haze, accelerate benzine quality namely upgrade, reduce the sulfur content in benzine, octane number in raising benzine. From at present the technology, increase benzine octane number best, most the method of environmental protection, join aromatic hydrocarbon namely. If take no account of the noxiousness, sex that cause cancer, benzene is first selection. Now, PX makes best choice. The expert is forecasted, the content of the PX in prospective benzine, will occupy than more.
The application in view of PX is very wide, be in industrialized, town to change fast developing China to jump gradually to the demand of PX.
Review the history, PX development of China experienced 3 level: Before 2000, progress is slower, but supply demand relations is balanced relatively, domestic self-sufficient rate was 2000 88% ; Arrived 2000 2010, chinese PX project develops quickly, productivity makes the world very quickly the first; 2010 up to now, home market demand goes high continuously, and cut down of PX construction hang back puts delay, produce can begin to cannot satisfy requirement.
The data shows, 2012, china is 13.85 million tons to the effective demand of PX, had become the PX with the greatest whole world to consume a country, 32% what take global consumption, but Chinese PX always is produced can be 8.8 million tons only, self-sufficient rate has 63% only.
Petrifaction refine changes Zhang Kehua of enmodern dining chairsgineering company assistant president to point out in, recently a certain number of year, domestic PX is produced can with annual 10% right-and-left speed are outspread, expanded 2011 1 million tons, enlarge produced 2.9 million tons 2012, still cannot satisfy the requirement of current home.
The expert predicts, if stop,be built or delay builds present PX project, predict to 2015 domestic PX self-sufficient rate will fall to 50% the following.
Raw material be enslaved to be enslaved to person, brought about the profit whole reach of catenary of chemical fibber industry, gather morely to PX link. Change character, supplier of abroad raw material acquired more interests, and ethical manufacturing industry suffers extruding fully. Zhang Kehua points out, japan, Korea export PX product to China, price of more homebred material wants tower above a lot of. The product value that always concerns with PX can deliver terminal link, be being returned finally is marry again arrives on consumer body.
Why is the foreigner afraid of PX——
The country waits in day Han and Singapore, because mature and cast-iron environmental risk pipe accuses to make PX project and residential area are in nearly,very close
Build a project to put delay in domestic PX, some even by permanent cancel when, the PX project of Japan, Korea is done however like a raging fire, become main entrance state of China.
Korea is the Asia's biggest PX production country, produce per year can control for 5.84 million tons, exit measures nearly 1.5 million tons. S-OIL is Korea one of 3 the mainest petrifaction businesses, 1.7 million tons of PX that its produce every year, 700 thousand tons of exit go to China. Last year, the PX unit with the world monomer the biggest scale that this company constructs in Wei Shan is already formal put into production, its are produced can be equivalent to offerring 3.2 billion layette every year to install for the whole world.
Japan produces big country as another PX, produce per year can exceed 4 million tons, half the number exports abroad. Last year November, company of Japanese JX energy and Korea SK collaboration build large-scale PX to produce a plant, this factory produces per year a quantity to will achieve 1 million tons after predicting put into production.
Singapore regards one of native pillar industries as PX, increase development strength ceaselessly. The Singapore that relies on to fill the sea to build Liu Ercheng makes rich corridor turns work area, it is at present the biggest petrifaction produces the Asia to spread base with content, also be the whole world the 3rd large oil refine base. 2012, here introduces to produce per year 800 thousand tons PX project again.
PX anti of China, advocate PX project is apart from residential area to want 100 kilometers at least not less, say this is international standard or international regulation. But in Singapore, PX device and residential area are only 900 meters of distances. Rest in the Unibrass faucet aerator ted States Si Dui, PX device is apart from the city zone to be 1.2 kilometers. Alive group is very multinational, residential area of PX project distance is not very far. Factory of refine of Japanese yokohama NPRC 350 thousand tons / year PX device, lie between a freeway only with residential area.
The PX project of these abroad can be as harmonious as the public coexist, main profit from matures and severe environmental hazard is in charge of control to spend.
Enterprise of foreign chemical industry all nots hesitate investment weighs gold, ensure utmost ground removes the negative effect that PX produces. For instance Korea SamSung path amounted to Er company to make prep above government stipulate the safety of 6 times runs a level: All use double and redundant setting on circuit, canalage; Adopt aggrandizement to harmful gas the processing means of 10 times; Ask tripartite company to detect discharged gas, make data has public letter power more; Undertake safety grooms every year to new employee 8 times, old stuff has drilling of 1—2 second safety every year; Every plant area has his fire control team; Have to the natural disaster such as be struck by lightning, seismic sea wave beforehand case.
In the meantime, the business that produces PX also accomplishs information as far as possible transparent, eliminate the people's insecurity. In Korea, the people can examfree norton internet antivirusine safe production information through the homepage of the enterprise at any time. In Singapore, the government still undertakes an important task that communicates with community and dweller.
More important is, PX project belongs to project of fundamental sex chemical industry, damage a risk to make control to PX project environment, had been current a more mature technology in globalization industry. "We do not have the thing with regard PX project as very dangerous. " Shijingjunzhao of undersecretary of ministry of safety of environment of society of company of Japanese JX energy expresses, the other product that the safety administration of PX turns industrial chain relative to Yu Shi, without what characteristic.
PX is in abroad is the chemical product of common, also can resemble steam derv in home same, make common chemical product. Once worked in PX production workshop overmuch year refine of Hainan of the petrifaction in currently holding the post ofchanges company general manager Wang Yubing says, china shows some PX plant, the PX project that develops in recent years especially, have higher technical level on the whole, level of management also is in the modernization of large plant to promote considerably. More delectable is, in recent years our country also is broken through somewhat on the core technology that PX manufactures, after becoming afterwards United States, France the 3rd country that masters core technology, because this our country is on PX production,can reach foreign level completely, realize safe and harmless production.
The fact tells us, PX item is other perhaps project of heavy chemical industry is not to propose the issue that does not propose, how be built however and how the problthe best selling watch casesem of operation. Rely on science and technology and management, project of heavy chemical industry also can build for the environment friendly model enterprise. For instance in the luxuriant name city that petrifaction Mao Mingshi turns company seat, air quality is done not have not only destroy because of huge petrifaction project, maintain all the time instead in one class, it is one of cities with countrywide air best quality. Be located in the petrifaction of Chinese oil Guangxi of upper bay for instance again, put into production is close 3 years, the around extremely tall to water quality requirement white cowfish that the environment learns the home to worry most is planted group of amounts did not decrease to still increase somewhat not only.
Chinese need PX is a fact. Because the dweller understands inadequately it is PX, good to do not believe PX project can manage and object PX, also be a fact. These happen often " of PX contend for " , for government, enterprise and people reason exploration China type weighed chemical development to offer a new chance. Among them first issue is, in the constructwatch case openerion that how government, enterprise invites the people to participate in PX with more open stance and management.
