LITHIUM HYDROXIDE PRODUCTION PLANT

Client: TIANQI LITHIUM AUSTRALIA [TIANQI LITHIUM KWINANA]
Project value: $700m
Location: Kwinana, Western Australia

MSP role: Head contractor EPC contract for the engineering design and construction of two lithium hydroxide production trains for a total output of ~48,000tpa, including development of a batch process and conceptual flowsheet into a world-scale continuous pyro/hydro-metallurgical process facility. Rotating equipment includes roasting and calcining kilns, fixed equipment includes hydrolytic chemical process, separation, crystallisation and drying/bagging plant. Site non-process infrastructure includes process control, warehousing and utility space, and Tianqi Australia’s new headquarters buildings.

Contract type: EPC, incentivised to a Target Cost Estimate (TCE), with agreed Key Performance Indicators (KPIs) for the target cost and schedule, and for safety, environmental and IR targets.

Project timing: Construction start 4Q2016, Commissioning start 2Q2019

The facility employs pyrometallurgical and hydrometallurgical circuits

Pyrometallurgical process includes large rotating kilns

Tianqi Lithium’s LHPP facility is a world-first continuous lithium hydroxide production plant, designed to convert beneficiated spodumene from Talison Lithium (Tianqi 51%) Greenbushes operation to produce ~24,000 tonnes per annum of battery grade lithium hydroxide per train for export.

MSP’s role included development of a batch process and conceptual flowsheet into a world-scale continuous pyro/hydro-metallurgical process facility, and appointment as head contractor for the EPC contract work. The contract initially contemplated one train at 24,000tpa, but was expanded to include a second train.

The facility is located in the Kwinana Industrial Strip, selected for its access to major package vendors, plant inputs including process gas, water and reagent suppliers, and export routing through the Port of Fremantle.

Significant packages included: bulk earthworks and civils, structural concrete and steel, structural and mechanical pipework, heavy rotating equipment installation, tank fabrication and installation, and electrical and control installation.

Specialised packages included: acid roast and calciner kiln/cooler manufacture, candle and plate filters, milling, crystallisation and drying circuits.

Peak construction workforce exceeded 1000, and the project achieved local content of more than 80%.
