Brine Treatment Process and Piping Design

Venture Engineering & Construction was contracted to provide a rare earth facility design support of a facility for purifying waste brine into a feedstock suitable for a downstream chlor-alkali plant.

Project Scope

  • Advancing the original concept which involved multiple steps of precipitation chemisty,
  • Re-purposing existing process facilities for brine treatment, using surplus equipment from other areas of the facility,
  • Developing a means to supply a uniform flow to the chlor-alkali plant from a variable supply; more specifically to:
  1. Simultaneously feed the chlor-alkali process with treated brine from the processing facility while diverting excess brine to the remote holding ponds, or
  2. Simultaneously feed the chlor-alkali process with treated brine from the processing facility while compensating for shortfalls by the feeding brine from remote holding ponds, or
  3. Continue processing waste brine flows without interruption in the event of an outage at the chlor-alkali plant, or
  4. Supply brine from remote holding ponds to the chlor-alkali process without interruption in the event of an outage at the brine processing facility.

Services Provided

Deliverables included:

  • Scrubbing of the original P&IDs and developing new P&IDs as required
  • Equipment list, instrument list, and valve list
  • Arrangement drawings and piping plans
  • Procurement of new and used equipment
