KEY ADVANTAGES

Our approach to developing the most efficient and sustainable process solutions, is often underpinned by our ability to utilise our process expertise to recover chemical products from waste streams, resulting in significant value creation.

Process Advantages

  • Improved water recovery.
  • Improved product, by-product and reagent recoveries.
  • Reduction of wastewater (including brine) production.
  • Lower specific energy use and reagent consumption.
  • Improvement in overall project economics.
  • Improved project sustainability profile.

 

TYPICAL APPLICATIONS

Our core technologies are typically suited to high concentration (high TDS) primary, process and waste streams, where processing with conventional technologies, is unable to adequately meet project requirements. These applications include:

  • Salar derived brines, rich in lithium, potash and other minerals.
  • Geothermal derived brines, particularly from lower-enthalpy resources, amenable to DLE related technologies.
  • Industrial brines, derived from desalination processes, particularly reverse osmosis (RO) reject brines.
  • Hydrometallurgical process streams, including process liquors and various waste streams.
  • Broad range of additional applications, where we are able to beneficially treat process streams, to create value. 

 

RECENT PROJECTS

Parkway has provided process expertise including in relation to the core technologies, to a diverse range of large global industrial companies seeking to improve the efficiency of existing project operations, or alternatively to support the development of greenfield project opportunities, through more innovative process flowsheet optimisation options.

Recent Projects Include

  • Development and evaluation of various brine processing flowsheets for production of minerals, including potash.
  • Investigation into processing waste liquors from various TSFs at tier-1 polymetallic mine, with core technologies.
  • Investigation into opportunities to recover minerals and reagents from a waste stream at a major nickel refinery.
  • Development of process to treat CSG derived brines and produce industrial chemicals (see Case Study, next page).
3) PROCESS SOLUTIONS
DEVELOPING INTEGRATED SOLUTIONS: In Partnership with Worley

At Parkway, we are focused on high value applications, particularly concentrated and/or complex solutions, where we work collaboratively with our strategic partners, including leading OEMs, to develop an end-to-end process solution.
In May 2020, Parkway entered into a strategic partnership with Worley, a leading global engineering company, with primary operations in the energy, chemicals and resources sectors. Parkway and Worley have joined forces on several innovative projects, which enabled the parties to apply their respective strengths and achieve great overall outcomes.
Through the established global strategic partnership, Parkway and Worley, are able to provide the complete project scope required for successful project delivery, from early-stage process and project concept development, through to project execution, inclusive of:

  • Process plant (Parkway provides process technology package).
  • Balance of plant (BOP), inclusive of non-process infrastructure (NPI).
  • EPC Management (EPCM) related services, to support project execution.

Global Strategic Partnership

 

CASE STUDY: Queensland CSG Brine Industry
  • The globally significant coal seam gas (CSG) industry in Australia is underpinned by greater than $100 billion in investment, however generates large volumes (~5GL) of waste brine annually. Despite significant efforts by industry over many years, no viable long-term solution has been developed to manage this highly complex brine.
  • Following extensive process evaluations, Parkway has developed a proprietary brine processing solution for the concentrated CSG derived brines. The Parkway solution involves processing the concentrated waste brines, to reduce waste volumes by >98%, whilst producing a range of valuable chemical products for local industry.
  • The proprietary process technology package developed by Parkway, has recently underpinned a detailed feasibility study (incorporating extensive process piloting), with a major global energy company.
  • In June 2023, Parkway announced the industry-wide implications of the proprietary technology to address the entire CSG industry’s waste brine challenges in Queensland, through the release of Master Plan, an ambitious agenda to potentially create in excess of $10 billion of value for the industry.
