Portland aluminum smelter

from Wikipedia, the free encyclopedia

The Portland Aluminum Smelter with an annual capacity of 345,000 tons of aluminum is in Portland in Victoria , Australia . The aluminum smelter is a joint venture between Alcoa World Alumina and Chemicals with a stake of 55% (of which 60% from Alcoa and 40% from Alumina Limited ), Chinese CITIC with 22.5% and Japanese Marubeni with 22.5%. The smelter is operated by Alumina Limited .

The aluminum smelter was built from 1986 to 1988. It consists of two Alcoa A817 cells for melting electrolysis with a current capacity of 310 kiloamps. Portland is the only aluminum smelter using this technology. Alumina is delivered biweekly from Western Australia on the ship The Portland . The aluminum oxide is transported from the port on a closed conveyor belt over several kilometers to the hut. Most of the aluminum ingots produced are trucked from Portland to other ports, although some are also shipped direct from Portland port.

The aluminum smelter was the cause of a fierce controversy in 1986. In 1984, under the government of John Cain, the ALP signed a joint venture agreement for the construction of the aluminum smelter, in which the government guaranteed the supply of electricity until 2016 and the price of the electricity World market price for aluminum coupled. This agreement meant that the electricity costs of the aluminum smelter were AUD 14 per megawatt hour (1.4 ct / kWh) and thus the cost of the state of Victoria was more than AUD 2 billion over the contract period of 20 years.

The Portland aluminum smelter consumes 18-25 percent of all electricity in Victoria, and since the majority of the electricity should come from the Latrobe Valley lignite power plant , it also meant that aluminum production was the main source of greenhouse gas emissions from Victoria is.

In March 2010 it was announced that the operators of the Loy Yang power plant had signed an electricity supply contract for both aluminum smelters with a term until 2036. The previous contracts expire in 2014.
