2. Introduction • Based on Dr. Basu’s Research which showed that bio-matter breaks down in supercritical water • Design a portable supercritical water reactor to break down dangerous bio medical waste

3. Design Criteria • The reactor will be designed such that pressure vessel certification will not apply. The design will follow pressure vessel codes regardless. • Adhere to all provincial regulations and codes • Adhere to ASME and relevant pressure vessel codes • Provisions for internal visibility • Generally safe and operational • Appearance creates awareness of its potential danger • Easily opened and closed reaction chamber • Portable

4. Supercritical Water • Operating Conditions • 600°C • 25MPa

9. Sight Glasses

10. Valves

11. Overflow Vessels

12. Safety • Safety is paramount for this project • Extensive stress calculations have been conducted on reaction vessel • Safety factor of 3 for reaction vessel • Swagelok VCR fittings weakest point 30 Mpa maximum pressure • Temperature reduced before valves • Temperature and Pressure decreased before valve network and overflow vessels • A safety valve will ensure that if the BPV does fail the pressure in the vessel will never go critical

13. Test Day • Used bubbling bed • Anaerobic Environment • Beef broken down into smaller molecules • Evidence of carbon residue • High pH water residue Where’s the beef?

14. Heater • Bubbling bed • At least 20 Watts • At least 700°C • Reduced cost • No increased safety if the pressure vessel goes critical

15. Instrumentation • Thermocouple • Omega Engineering Pressure Transducer

16. Budget

17. Got Beef? Any Questions?
