2016 is the year of the transformation of chemical strength

In order to ease the dependence on polyolefin import, the country has been vigorously developing coal to olefin technology. In 2015, a large number of domestic coal-to-olefin units were put into production, but the collapse of crude oil price hit the coal-to-olefin industry and eased its impact on the polyolefin market. However, the large-scale production of coal-made olefin devices is irreversible, and this technological revolution will break the supply pattern of the domestic olefin industry and reprice LLDPE and PP. Some coal-to-olefin processes produce PE and PP at the same time, and the proportion of PP is higher than that of PE, so the capacity growth of PP will be higher than that of PE. In addition, after the rapid expansion of production capacity and price decline, the growth rate of PTA production capacity gradually slowed down. The bankruptcy of Far East Petrochemical is a sign that the survival of the fittest in PTA industry has begun.

The price of refrigerant R22 increased

Refrigerant market R22 rose this week, the price of 300-500 yuan/ton. This round of increases mainly due to the reduction of quota, such as Shandong Dongyue quota remaining, manufacturers support the price sentiment again high, at the same time, the raw material end of chloroform market significantly upward, hydrofluoric acid weak stable, support is ok, by the quota and cost surface support, refrigerant R22 price rebound, but the demand side support is weak, continue to slump, so R22 significantly up temporarily no actual driving force, After the weak maintain stable market or will continue. According to the price monitoring, as of November 5, the price of refrigerant R22 market mainstream manufacturers is about 13000-16000 yuan/ton, and the actual transaction price is slightly lower.

Is r22 refrigerant and r134a common? Refrigerant science tips

Known as environmentally friendly refrigerants, other refrigerants such as R410A, R440A and R407C in the HFCs class are superior to R134a in efficiency, but they also have disadvantages such as high working pressure, high requirements for the optimal and pressure resistance of pipeline components, improved design of heat exchanger and unit, and high investment in operation and maintenance costs. The application of large refrigeration units is not adapted to the basic situation of our country. This is the reason why the international convention can relax the period of using HCFCs in developing countries, and the result of the collective efforts of developing countries.

What are the product uses of methyl chloride

Methylene chloride is mainly used in the production of methyl chlorosilane, and 50% to 90% of the world's methylene chloride is used in the production of organosilicon. In addition, it is also used in the production of methyl cellulose, tetramethyllead, herbicide, butyl rubber, quaternary amine compounds, etc. It can also be used as refrigerant, foaming agent, and solvent of rubber, resin and organic compounds. Used medically as a local anesthetic.

What is the difference between carrier refrigerant and refrigerant

In a gas compression refrigerator, gas refrigerants, such as air, hydrogen, helium, etc. are used, and they remain gaseous throughout the refrigeration cycle. In an absorption refrigerator, a binary composition consisting of an absorber and a refrigerant is used. A solution, such as ammonia, lithium bromide (molecular formula: LiBr), used as a working fluid. White cubic crystal or granular powder, soluble in water) and water; Steam jet refrigerators use water as refrigerant.
