PX project does not contivancouver to harrison hot springsnue to develop even
Progress of modern economy society already cannot leave PX, our country already became the world's greatest PX to produce country and consumptive country, so ——
If see the catharsis on the dress carefully explain, can discover fabrics can tag normaharrison hot spring weather forecastlly " pure cotton " , " polyester fibber " , " polyester fiber " etc, at the back of this two kinds, be the downstream product of PX. Actually, case of water bottle of carapace of the phone beside us, mobile phone, mineral spring, computer, capsule, curtain, camera is waiwatch case openerted a moment, do not have with material one as not associated as PX. In the daily life of modern, PX is derived article meeting the eye all is. The economic society of contemporary China develops, cannot have left PX. Our country already became the world to the biggest PX is produced and consume a country, produce can take the whole world about 20% , consumption takes the whole world about 32% . Predict in the near future, our country PX still needs a large number of imports. Let us follow the expert's line of sight will examine, PX project, still need to continue to develop after all?
modern dining chairsThe national economy and the people's livelihood cannot leave
The formal name of PX is " 1, 4— xylene " , cry again " to xylene " , it is one kind comes from petrolic colorless and transparent liquid, also be a large amount of important chemical foundation raw material. In contemporary petrifaction system, the aromatic hydrocarbon industry that is a delegate with PX and the alkene industry that are a delegate with ethylene, call petro-chemical " two everybody a group of things with common features " . In economic domain, chain of PX downstream industry is long, additional cost is high, accordingly, PX production treatment also is known as " gold property catenary " .
"PX project is the extract device that points to construction PX commonly, the north face shirtsmaterial such as the toluene of the generation in process of oil of bisect heat up in a steamer, mixture xylene undertakes branch is changed, different compose, detached, then extract PX. PX is right change ' head having oil, without spend remaining part ' industrial position, spin sense of petrifaction industry catenary is great. " Wu Shikui of assistant dean of chemical industry of Guangdong petro-chemical institute anfree modern dining chairsd environmental project college introduces, after PX device builds, store with commodity form so, carry, sale, on the spot of the mixture xylene that is put in safe hidden trouble, toluene by product of translate into solid (polyester) . Below this kind of circumstance, of mixture xylene store the quantity decreases considerably, external (tank car) carry, sale seldom is done not have even, the risk also is reduced greatly.
Wu Shikui expresses, in petro-chemical factory, aromatic hydrocarbon combines device to be end product with PX normally, be opposite as downstream essence benzene 2 formic acid (the raw material of PTA) product. In addition, also a few PX are opposite in the best selling north face shirtsherbicide and couplet use as in xylene solvent, wait for the producer goods of the product as medicine, coating, fuel, printing ink.
In catenary of PX—PTA— polyester industry, the PX of 65% above is oxidized to become PTA, and the PTA of nearly 90% is changed to become polyester. The downstream product of polyester includes polyester fibber fiber, carefe and component of all sorts of insulation, material that pack, industry to wait. This among them design and color of our most familiar nothing is more... than the clothes with each different, different quality of a material, still have mineral water bottle, coke bottle.
As we have learned, at present the clothing fabrics of 70% comes from our country polyester fibber fiber, our country produced polyester fibber fiber 2011 27.78 million tons. Be equivalent to computation of crop of 70 thousand mus of cotton by fiber of 10 thousand tons of dacron, be equivalent to crop of 1.9 trillion mus of cotton in all. Spin industry uses PX product in great quantities managing kind cotton uses the land, assured crop of our country grain secondhand sow an area.
According to statistic, car of the our country end 2012 retains the quantity exceeds 120 million, car tail gas has become the number one killer of urban mist haze. The important way that free watch casereduces urban mist haze accelerates oily quality quantity to upgrade namely, the octane number in raising benzine (benzine grade, be like 97# ) . Factory of big temper with fire promotes high-octane idea is to join aromatic hydrocarbon, the xylene of lowest of the noxiousness in its composition assumed aromatic hydrocarbon to carry high-octane mission, and many PX is contained in xylene. Accordingly, wu Shikui expresses, "No matter be to reduce the risk in mixing xylene to carry, still raise octane number to upgrade oil is tasted, the function that PX improves air quality secondhand cannot small gaze " .
Depend on an entrance to have a risk
2010, our country becomes the world's greatest PX to produce country and consumptive country at the same time, produce can take the whole world about 20% , consumption takes the whole world about 32% . Occupy Cao Xianghong of academician of Chinese Academy of Engineering to divulge, chinese PX was produced 2012 can be 8.8 million tons, import volume achieved 6.29 million tons, of PX external depend on sb or sth for existence is spent adjacent 45% . In fact, the yield of Chinese PX can jump from 2.69 million tons of 2005 8.14 million tons of 2010, exceed the United States to jump house world first the first. Since have so tall yield can, why can you still appear so big demand gap?
"From 2002 PTA invests ' lift a ban ' since, PTA is shown erupt the gender grows. Although PX is produced,can increasing, but amplitude cannot can increase with the yield of downstream PTA match. " petrifaction of advisory company of China International engineering spins Guo Chen of development department section chief gently to explain. The basis is forecasted, as PTA new increase production can drive entirely 2013, domestimodern dining chairsc apparent demand or will achieve 18 million tons, PX supplies breach to will amount to 8 million tons of above. Accordingly, famous finance and economics comments on person leaf wingceltis to express, in Chinese manufacturing industry, search the odds that produces not can superfluous item, very little, PX project is among them one of. north face shirts
"This is us only a product of PX make it (for instance dress) effective demand, if resemble day of Han exporting PX raw material directly euqally, PX still has larger development space. " Guo Chen says.
Wu Shikui expresses, PX project is opposite aground again and again the PX that home is in short supply originally is supplied is one disaster after another undoubtedly, this will force China to import PX and relevant product to give more foreign currency. At present manufactured goods of PX of Han of Chinese entrance day has been forced to adopt " the price that press a month " means. Be in this year June, price of PX finished products relatively the corresponding period rose 2012 200 dollars / ton.
Guo Chen is anxious, upriver PX price is exorbitant, will bring about downstream PTA and polyester kind the profit space of the product is squeezed to occupy, this is very adverse to the development of relevant industry catenary. The consumer that serves as terminal also should be polyester necessarily kind the excessive price of the product buys sheet, this means the money of beautiful as much, will buy more than be being gotten less before product.
Because practice control of case of finished product oil price,be in our country, big temper with fire changes an enterprise to be able to use business of oil refining of chemical business allowance commonly. The expert states enterprise of our country oil refining is met normally the best birth rate that the market level according to characteristic of character of respective crude oil, device and finished product oil and chemical product will come to to decide the chemical product such as steam derv, aromatic hydrocarbon. Accordingly, the immediate impact of unbalance of catenary of industry of PX upper reaches is ability of profit of oil refining company reduce.
Go aground again and again in domestic PX project while, PX produces the country such as Korea, Japan and Singapore can firm however in have add, japan gives industrial district of island of smooth, water, path of Korea SK the sources of energy, SamSung amounts to the enterprise such as Er and island of Singapore abundant corridor to own PX plant. As we have learned, korea S-OIL company is running the world at present project of PX of the biggest per unit area yield, produce per year nearly 1.7 million tons, the product basically will sell past China. It is PX project likewise, why the pay of domestic abroad " is glacial fire double day " ?
To thinking of PX further
The controversy that whether although come nearly 20 years,economist enters course of study of heavy chemical industry to develop level about our country never discontinuous, but major ecowatch casesnomist thinks, course of study of heavy chemical industry is the bank that the past does not stride in our country industrialized road, we want to be in modern international trade not person of be enslaved to be enslaved to, must develop be course of study of heavy chemical industry with petrifaction, car.
In fact, as the addition of income, partial dweller especially economy developeds the dweller of the area has entered big spending level, wait to changed industrial product to generate moderate consumptive demand again to such as car, housing. On this foundation, related to PX the consumption of the product also is met necessarily when the river rises the boat goes up too, maintain a very big increment.
Face future, PX project is returned to the spin industry develobrass faucetpment, important sense that enlarges obtain employment will highlight further.
An expert expresses Chinese petrifaction, PX is very tall to the requirement of capital and technology, belong to high capital concentrated model industry. The obtain employment number that every build project of a PX to drive is limited, the ability when delivering the view to relevant industry catenary only discovers its meaning, involve the chemical fibber industry of couplet and spin trade with PX photograph, the labor that belongs to a tradition is concentrated model industry, centered many obtain employment population.
Statistic shows, domestic spin industry was close to from trade number 2012 22 million, about 7% what take Chinese manufacturing industry, inducted a country effectively to change able-bodied person. Below this kind of circumstance, if the yield of PX can backwater not before, can rely on entrance PX to satisfy downstream and exuberant requirement only, spin industry, chemical fibber industry will suffer concussion, the obtain employment situation of the industry also nots allow hopeful. Obtain employment is connecting the people's livelihood, progress of economy of current our country is lying " climb slope to cross bank " crucial phase, must put effort morely enlarge obtain employment to come up.
Face future, PX and the product will act more important role in economic domain related its. Suffer visit an expert to express from this, PX item is other perhaps project of heavy chemical industry, be in contemporary China, "Not be to should be built, the problem of this development, after building however, how to strengthen supervisory management further, strengthen the question that answers sudden incident management " .
