Benefits
Existing PPA production depends on burning sulfur from Oil & Gas to make sulfuric acid. Travertine PPA production recycles sulfur within a closed loop.
Existing PPA production requires large plants to achieve economics of scale. Travertine PPA production uses modular electrolyzer units that allow small scale plants.
Existing PPA production creates 4-6 times as much phosphogypsum waste as product. Travertine PPA production produces no phosphogypsum waste.
Existing PPA production has a carbon footprint of around 1 kg CO2/kg product. Travertine PPA production uses renewable electricity for a carbon negative product footprint.
Existing PPA production trains are old & optimized for a single phosphate rock source. Travertine PPA production is feedstock flexible and designed to handle either igneous and sedimentary phosphate rock feedstocks.
Existing phosphate plant production yields are falling below 90% recovery. Travertine PPA uses advanced extraction and purification technologies to maintain best in class phosphate recovery.
Applications
Purified Phosphoric Acid (PPA) is widely used for food and beverage, fertilizers and nutrients, and increasingly for battery manufacturing.
Application Highlights
-
Fertilizers
Purified phosphoric acid offers a highly pure and effective source of phosphorus for fertilizer applications, providing advantages in nutrient availability and soil management.
-
Energy Storage
Purified phosphoric acid (PPA) is a key raw material for manufacturing the cathode active material for lithium iron phosphate (LFP) batteries.
-
Food & Beverage
Purified phosphoric acid is a versatile and widely used food and beverage additive that acts as a pH regulator, preservative, and flavor enhancer.
-
Metal Processing
Purified phosphoric acid is widely used in metal processing for rust removal, surface preparation (phosphating), and electropolishing.
