EPCM Services for Unique Pilot Plant Installation
In Jonquiere, Québec, Tetra Tech is providing engineering, procurement, and construction management (EPCM) services to Alcan for the development of a first-of-its-kind pilot plant for spent pot lining.
With a capacity of 80,000 tons per year, the new plant uses a low caustic leaching and liming process, a new hydrometallurgical technology developed by Alcan. The project also involves implementing other new technologies at the pilot facility, including a new grinding circuit, new reactor processes, and a new evaporation and crystallization process.
As part of this EPCM effort, Tetra Tech manages the scope and evaluates change requests; identifies project risks; provides value optimization services (identified more than CND $10 million in overall savings); works with regional suppliers; and implements procedures to help manage environment, health, and safety at the plant.
