Q:Which products can be produced in the petrochemical chain?

Domestic enterprises in the ethylene plant technology has been quite mature, such as the ethylene unit in the leading unit - ethylene cracking furnace

Q:Petrochemical products are how to change from oil into a variety of products?

fractionationBoiling point hydrocarbons increased with the increase of the carbon number, when heated, hydrocarbons with low boiling point to gasification, after first condensation separation. To separate compounds of different boiling points, this method is called fractionation. Fractionation is a physical change.The fractionation process is carried out in a high tower. The tower has carefully designed layers of tower plates with a certain temperature difference between the trays to obtain different fractions. Fractionation was carried out at atmospheric pressure to obtain a low boiling fraction, and then a high boiling fraction was obtained under pressure relief. Each fraction also contains a variety of compounds that can be further fractionated.

Q:Trouble you experts say, oil and petrochemical industry chain is how convergence,The name of the product, the relationship between the input and output of the upper and lower products (such as: a ton of X can produce about how many tons of Y),Production and development of various products in the world, China and other countries,What are the representative enterprises in the industry.

Analysis of chemical industry product price is not easy, it is difficult largely because of "intermediate" (referring to the petrochemical industry chain is located in the middle part of the product, the product is just a chemical raw material, no other use value.) Existence. In view of the lack of "intermediate" petrochemical trading in the spot market, "intermediate" prices often by the manufacturer according to the cost and profit of processing enterprise price formation, and the buyer can only passively accept, this is the so-called price monopoly. In the petrochemical industry chain upstream enterprises, due to the size of the investment and has this feature. In addition, for most petrochemical "intermediate", China's import dependence is often higher than 30%, which led to the price in the international market has a great impact on China's price, sometimes even decisive. Closer to the top of the industrial chain, the impact is more obvious.

Q:What are petrochemical products

gasolineIs the largest consumption of varieties. The boiling range of gasoline (also known as the 30~205 range) ~ C, density of 0.70~0.78 g / cm 3, according to the quality of commercial gasoline oil in the combustion of anti knock combustion performance of the cylinder distinction, marked as octane number 70, 80, 90 or more. The number of Yu, the performance of good, gasoline is mainly used as automobiles, motorcycles, boats, helicopters, agricultural and forestry aircraft fuel. Goods are added to gasoline additives (such as ANTIKNOCKS tetraethyllead) to improve the use and storage performance. Environmental protection requirements, the future will limit the content of aromatics and lead.

Q:Fuel oil, base oil, petrochemical products, lubricating oil and so on to import from abroad

Poultry and livestock feed import tax rate from the current 5% to 4%, feed additives such as mineral additives and chemical elements from the current rate of up to 6.5% of the tax rate. Some steel, such as angle steel import tax rate from the current 0% to 10%.It depends on which country you are importing, and what is the most favored nation treatment of the importing country.And in order to obtain preferential import tariff rate, the exporter shall be required to provide a certificate of origin (FORM A)Certificate of origin is China's export products have the force of law to enjoy official document further reduction of import tariffs on the basis of MFN tariff rate in the country.

Q:Is it the same as oil refining and petrochemical?

This I know, ha ha. I came out of the oil.Several major oil companies in China, their business is divided into this large: oil production, oil refining (petrochemical), drilling, drilling equipment manufacturing.

Q:Whether the petroleum products

The so-called catalytic cracking is the use of heat, pressure and catalyst to break the heavy oil into light oil, mainly gasoline. Another method of refining is polymerization, which is just the opposite of cracking: the synthesis of small molecules into large molecules, the extraction of the light gas into gasoline and other liquids.

Q:At present, more than 70% of the chemical products are low value-added products, but also a serious excess capacity, then what is a high value-added products, please god,
