The Alma plant (Canada) started in 2001 at a current intensity of 330kA using AP33 technology. Following the start-up, the plant productivity steadily improved year after year. Lately, a major step in current intensity was undertaken with the development of the AP44 technology operating at more than 440 kA. The implementation strategy in Alma includes the validation of an operating point at 400 kA and 440 kA as well as the transition between these two points.
The new cell design at 440 kA requires the operational practices to be adapted. The new operating points (400 kA, 440 kA and transient) will also require the optimization of various control parameters.
The development of the AP44 technology and the related operational adjustments allowed to validate the initial design assumptions and to identify new improvement avenues to support the development of present and future AP4X technological options.
