自1975年以来，位于圣让-德-毛利安(LRF)的铝业Pechiney研究中心一直致力于设计、测试和完善铝材Pechiney点送预焙电解槽。1979年，随着圣让F线的建造和启动，AP18电池(180kA)开始工业化。下一代AP30(300kA)的原型始于1981年，于1986年在Saint-Jean G线上推出。在电解槽设计的同时，开发了有效的过程控制系统来试验氧化铝加料和镀液组成。这些罐子目前总共生产460万吨铝，相当于全球年产量的18%。在，该研究中心面临着一个新的挑战：突破减产单元的规模上限，以进一步提高绿地项目的盈利能力。这一新一代的开发也是对铝Pechiney电解信息系统进行重大重新设计的机会。AP50技术拥有十年半工业运营的记录，拥有三个原型，现已准备好用于工业实施，并使绿地冶炼厂的投资回报方面取得重大突破。
Since 1975, the Aluminium Pechiney Research Centre at Saint-Jean-de-Maurienne (LRF) has been concentrating its efforts on designing, testing and perfecting the Aluminium Pechiney point-fed prebaked reduction cell. In 1979, the AP18 cell (180 kA) was industrially launched with the construction and start-up of the F line in Saint-Jean. The following generation, the AP30 (300 kA), with prototypes started in 1981, was launched in 1986 on the Saint-Jean G line. Along with cell design, efficient process control systems were developed to pilot alumina feeding and bath composition. Together, these pots are currently producing 4.6 Mt of aluminum, i.e., 18% of the world's overall yearly production. In 1989, the research centre faced a new challenge: to push the limits for the size of a reduction cell to further improve the profitability of Greenfield projects. This new generation development was also the opportunity for a significant redesign of the Aluminium Pechiney electrolysis information system. With a track record of ten years of semi-industrial operation with three prototypes, the AP50 technology is now ready for industrial implementation and enables a significant breakthrough to be made in terms of return on investment of a Greenfield smelter.
