Hatch provides EPCM services to clients who produce more than half of the world’s supply of alumina and two thirds of the alumina outside of Russia and Eastern Europe.

We are committed to delivering aggressive schedules, budgets, debottlenecking solutions, and scale-ups to full production. We deliver facilities that set new standards for safety, reliability, maintainability, economy, and operability.

Hatch provides unique expertise in proven high-temperature digestion design and the application of full Bayer refinery design. We have extensive experience in flash-train design, bauxite assessments, ore characterisation, tube digestion and greenfield mine and refinery engineering.

Our expertise with patented tube-digestion technology has been demonstrated in Rio Tinto Alcan’s Yarwun 2 Alumina Refinery and the Korean General Chemical Corporation’s Alumina Refinery. The Yarwun 2 includes two digester units that are one million tonnes each, the largest single-stream high-pressure Bayer digestion units in the world. We are also providing a Hatch-designed indirect bauxite slurry-heating system.

We have the experience to deliver the full suite of services from preparation of feasibility and site selection studies to completion of start up planning and construction.
