Case Study | Chem-Aqua | How NCH Chem-Aqua Helped a Brewery Save Big on Glycol System Costs, Sustainability, and Carbon Footprint

The sustainability partnership with one of the Largest Brewery in Asia resulted in substantial environmental and financial returns.

The proactive use of Chem-Aqua 54766 patented close loop corrosion inhibitor stabilized the glycol system, avoided massive replacement costs, conserved water and chemicals, and significantly reduced the carbon footprint — all hallmarks of a high-ROI, sustainable initiative.

Sustainable Achievements:

• Water Conservation
• Saved: 500,000 Liters of fresh demineralized make-up water
• Impact: Reduces freshwater consumption and operational costs

Chemical Savings (Glycol)

• Saved: 38,000 gallons (143 m³) of Propylene Glycol
• Impact: Prevented total system replacement; stabilized existing glycol with CA 54766 treatment

Carbon Footprint Reduction

• Estimated CO₂e Avoided:
  • EU Model: 686 metric tons
  • Carbon Cloud Model: 1,296 metric tons

Financial Savings

• Total Cost Avoidance: approx. USD 800K–1M
• Impact: Major reduction in capital expense by preserving current glycol system

Equipment Life Extension

• Prevention of Corrosion: System life potentially prolonged to 25+ years Health & Safety Improvement
• Stabilized glycol parameters (pH, Reserve Alkalinity, PO₄) improved operational safety
