London, October 10: Alcan is updating its AP50 technology and should be ready to apply it to a smelter in the next 2-3 years, said chief executive Dick Evans. He also said: "We continue to update the AP50 technology and it is very likely that we will be deploying on a certain smelting in the next 2-3 years." Currently, 80% of the newly installed capacity in the world except China is using Aluminum Canada's AP18. And AP30 technology. Last year, 3,858 AP30-equipped electrolytic cells produced 3.6 million tons of aluminum, equivalent to 14% of global production. Evans said: "Through research and development, we will continue to improve our technical position." And stressed that technology has shifted from AP30 to AP35 and AP37. He also said: "Kitimat smelters will use AP37 technology." And pointed out that the modernization plan to increase the production of factories in British Columbia over 60% to 400,000 tons. China's aluminum smelters prefer to use pre-baking technology. “We are unwilling to apply the latest and best technology to China because there are more risk of leakage. China has a more economical solution than AP35, but if you want to operate a smelter for 30 years, it is better to use The world's largest technology, AP35, will be followed by AP37 and even one day the technology will reach AP50.” In 2005 Alcan invested 227 million US dollars in technology research and development.
