Is there any difference between heavy aromatics and light aromatics?

Date:2017-05-25 Author: Click:

  Light aromatic hydrocarbons and heavy aromatics are alkanes or alkenes containing benzene rings. Heavy and light aromatics are distinguished by the length of carbon chains of benzene rings linked to alkanes or alkenes. Of course, the long carbon chains are heavy aromatics, while the shorter ones are light hydrocarbons.

  Aromatic solvent oil is one of the five major types of petroleum products. Solvent oil has a wide range of uses. Consumption of the largest amount of paint solvent oil (commonly known as paint solvent oil), followed by edible oil, printing ink, leather, pesticides, pesticides, rubber, cosmetics, spices, pharmaceuticals, electronic components and other solvent oil. At present, there are about 400-500 kinds of solvents sold in the market, among which solvent oil (hydrocarbon, solvent, benzene compound) account for about half. Aromatic hydrocarbon, usually a hydrocarbon containing the benzene ring in a molecule. Is a closed class. With the basic structure of benzene ring compounds of this type are found early in the history of the aromatic flavor, so that these hydrocarbons to aromatics, later found not having aromatic hydrocarbons are taste uniform follows this name. Such as benzene, xylene, naphthalene and so on. General formula of benzene homologue is CnH2n-6 (n = 6). The number of Pi of aromatic hydrocarbons is 4n+2 (n is a nonnegative integer).

  The company's heavy aromatics plant was built in 2004, two in April 2016 and put into the device, heavy aromatics device is based on the summary of the experience of other domestic manufacturers and technology, after eight years of exploration and reform, we can produce all kinds of customers to meet the boiling range of products. At the same time, my company uses its own technological advantages, focusing on the manufacture of hydrogen peroxide solvent, not producing other uses and types of solvents. Our company's heavy aromatic quality management system meets the GB/T19001-2008/ISO9001:2008 standard. The products of heavy aromatics raw material is the main source of the refinery of Sinopec, the main technical indexes of the products is the content and the sulfur content of aromatics, our company is used in Sinopec Yueyang Changling oil refinery and Nanjing oil refinery by catalytic reforming unit to produce three toluene raw materials, the raw material passes through the vapor and liquid two hydrogenation under high temperature desulfurization and. The end of sulfur content less than 0.3PPM, the aromatics content is as high as 99%, at present, heavy aromatics Changlian Sinopec and Nanjing oil refinery is one of the best raw material for petrochemical industry. Our company has its own wholly-owned subsidiary of Yueyang Zhongshun logistics limited liability company, transport vehicles owned 25 Taiwan 50m fand, can guarantee the timeliness of delivery and ensure the quality of the products in transit.
