SRIC said that Ineos, a subsidiary of Ineos, is currently building a new phenol-acetone complex in Zhangjiagang, China. The designed capacity of the plant is 400,000 tons/year of phenol and 250,000 tons/year of acetone, which is expected to be completed by the end of 2009. Ryan Jackson, consultant of Tecnon OrbiChem, headquartered in London, United Kingdom, points out that global cumene production capacity is expected to grow at an average annual rate of about 3% in the next few years, while capacity growth in Asia will increase. Annual average of 6% to 8%.
According to Jackson, the Middle East will add a lot of cumene production capacity from 2010. Borealis and Abu Dhabi International Petroleum Investment Co. (IPIC) recently announced that they have signed a memorandum of understanding with the Abu Dhabi Investment Commission to prepare to invest billions of dollars in the construction of a petrochemical complex project in Abu Dhabi. The project will include a world-class naphtha cracker and a facility for the production of propylene and ethylene derivatives. It will also include world-class reformers and xylene, benzene, cumene, phenol and derivatives.
He also pointed out that the operating rate of cumene plants in most regions of the world will reach 100%, but the operating rate in North America will remain at a low level of 80% to 85%. This is because there is only excess production capacity of cumene in the United States.
According to statistics, more than 90% of cumene is used to produce phenol and produce acetone. In addition, cumene can also be used to produce coatings, varnishes, and enamels, as well as certain petroleum-based solvents and high octane aviation fuel components. It can also be used to make acetophenone, α-methylstyrene and peroxides, as well as catalysts for the polymerization and oxidation processes.
According to the latest statistical data from SRIC, the global production capacity of 14.521 million tons/year of cumene is specifically distributed as follows: North America: 4.29 million tons/year, South America: 310,000 tons/year; Western Europe: 3.43 million tons/year, Eastern Europe The area is 833,000 tons/year; in the Asia Pacific region, China is 1.374 million tons/year, Japan is 1.63 million tons/year, plus South Korea, Singapore, India, etc. The Asia-Pacific region totals 5.358 million tons/year.
Iron-based alloy powder is commonly used in plasma transfer arc welding (PTAW) due to its excellent mechanical properties and high resistance to corrosion and heat. This type of powder is typically composed of iron as the base metal, along with various alloying elements such as nickel, chromium, molybdenum, and tungsten.
The specific composition of the iron-based alloy powder may vary depending on the desired properties and application requirements. For example, adding nickel can increase the strength and toughness of the weld, while chromium enhances the corrosion resistance. Molybdenum and tungsten are often added to improve the high-temperature strength and creep resistance of the weld.
Iron-based alloy powders for PTAW are available in various particle sizes, typically ranging from a few micrometers to several hundred micrometers. The powder is usually fed into the plasma arc through a powder feeder, which ensures a controlled and consistent supply of powder during the welding process.
During PTAW, the powder is melted and deposited onto the workpiece, forming a weld bead. The high energy plasma arc provides the heat necessary to melt the powder and the base metal, creating a strong and durable weld joint.
Overall, iron-based alloy powder for plasma transfer arc welding offers excellent weldability, high mechanical properties, and resistance to corrosion and heat, making it suitable for a wide range of applications in industries such as aerospace, automotive, and power generation.
