  1. Susterra® 1,3 Propanediol For Brewery Heat Transfer Fluids Susterra® 1,3 Propanediol offers system owners an innovative, bio based glycol alternative for glycol loops

  2. Glycol Viscosity Comparison Susterra® 1,3 Propanediol exhibits lower viscosity in low-temperature conditions like those in brewery heat transfer loops, improving efficiency of the system.

  3. Comparison of Pumping Pressure: Susterra® 1,3 PDO vs PG Properties at -10º C 40.5 wt% PG 40 wt % PDO At -10º C, a 40% PG /60% water solution requires 2.4 times the pumping energy as a 40% Susterra®/ 60% water solution.

  4. Freeze Points of Aqueous Glycol Solutions Susterra® 1,3 Propanediol lowers freeze points in applications like brewery heat transfer loops.

  5. Glycol Cracking Study Results • Glycol cracking occurs as heat transfer fluid sees temperature fluctuations, producing corrosive organic compounds and darkened fluid. • This often results in premature replacement of the HTX fluid • DTL evaluated the relative stability of three glycols, using the same inhibitor package PG PDO EG After testing, the Susterra®-based fluid exhibited significantly less darkening than the PG and EG fluids

  6. Fluid Comparison: Nitrite Levels The sample containing inhibited Susterra® retained significantly more nitrites than the inhibited PG and EG samples

  7. Fluid Comparison: Glycolate Levels The Susterra®-based fluid produced fewer glycolates than the inhibited PG and EG fluids

  8. Susterra® Propanediol Achieves NSF International Nonfood Compounds Registration • 2010 Press Release: • DuPont Tate & Lyle Bio Products is excited to announce that Susterra® propanediol has NSF International Nonfood Compounds Registration. Susterra® is now acceptable as an ingredient for use in heat transfer fluids with incidental food contact (HTX-1) for use in and around food processing areas. • Susterra®propanediol offers formulators and suppliers a renewably sourced glycol base that meets the NSF International Registration Guidelines for Proprietary Substances and Nonfood Compounds. • Formulators using NSF Registered Ingredients need only identify the Susterra®propanediol name, the NSF Registration No. 141749, and concentration of Susterra® in the finished product of their respective application form. Ingredient for use in Heat Transfer Fluids with Incidental Food Contact (HTX-1) Susterra® is approved as an ingredient for use in HTX with incidental food contact for use in and around food processing areas including breweries.

  10. Glycol Comparisons

  11. Thermal Stability: Glycol Cracking Simulation Solar thermal HTX often exceed 200C at elevated pressure during low flow or stagnation events, causing glycol cracking and production of corrosive organic compounds When paired, the inhibitors and Susterra® exhibited superior thermal stability vs. the PG and EG inhibited glycols • This study was conducted to evaluate relative stability of three glycols, using the same inhibitor package (2.2% of #2792) • Concentrated glycols: • 712-132A: 1,2-Propanediol-based fluid (PG) • 712-132B: 1,3-Propanediol-based fluid (PDO) • 712-132C: Ethylene glycol-based fluid (EG) • Simulate semi-closed loop solar HTX fluid application; boil samples in a reflux condition for 16 hours and analyze the residual HTX fluid: • Reflux temperature: 362°F to 392°F (183.3°C to 200°C) • Boiling points at 1 ATM: • PG = 371°F (188.3°C) • PDO = 417°F (213.9°C) • EG = 387°F (197.2°C)

  12. Enabling a Renewable Economy... From: Molded Parts Oil Refining Chemistry Resins The source is not renewable To: Fibers Metabolic Engineering Biomass Feedstock Crops The source is renewable

  13. Susterra® Life Cycle Assessment* Comparison • From “cradle-to-gate,” the production of Susterra® consumes 40% less energy and reduces greenhouse gas emissions by more than 40% versus petroleum-based 1,3-propanediol and propylene glycol. *Susterra® LCA data based on Loudon process design data; peer reviewed by Five Winds International

  14. Japan Case Study: HTX for Beverage Processing Susterra® -based fluid is being used in Japan as a heat transfer fluid with low viscosity that is safe for use in food & beverage processing plants
