1 Propane- air (SNG) … in the world of natural gas

2 Objectives Synthetic Natural Gas background Applications Guidelines Summary Synthetic Natural Gas background Applications Guidelines Summary

3 Natural Gas Readily available Low cost Most types of equipment use Natural Gas Clean Readily available Low cost Most types of equipment use Natural Gas Clean

4 Natural Gas Disadvantages Not available in remote locations (but may be planned for future installation) Demand exceeds supply in peak periods (particularly winter) Pipelines may break (typically cause extended outages) Not easily stored at user site Not available in remote locations (but may be planned for future installation) Demand exceeds supply in peak periods (particularly winter) Pipelines may break (typically cause extended outages) Not easily stored at user site

5 Synthetic Natural Gas May be used in locations planning future natural gas (Bridging application) May be used to supplement natural gas when supply is limited (Peak Shaving) May be used to replace natural gas in the event of supply disruption (Back-Up) May be used in locations planning future natural gas (Bridging application) May be used to supplement natural gas when supply is limited (Peak Shaving) May be used to replace natural gas in the event of supply disruption (Back-Up)

6 Air LPG SNG SNG: A mixture of LPG + Air to simulate Natural Gas

7 SNG Characteristics Direct replacement for natural gas No burner replacements or adjustments No pressure changes needed Works in all fuel applications Direct replacement for natural gas No burner replacements or adjustments No pressure changes needed Works in all fuel applications

8 Wobbe Index: a measure of the ENERGY being provided to a combustion process. SNG to NG INTERCHANGEABILTY SNG acts like Natural Gas…

9 Natural Gas SG = 0.6 and the Calorific value =935 BTU/SCF SNG SG = and the Calorific value = 1421 BTU/SCF Wobbe Index = 935 = m Wobbe = 1207 Fuel Interchangeability Wobbe Index

10 No pressure changes No orifice changes Seamless fuel swapping Natural Gas: 935 BTU/SCF SG Synthetic Natural Gas: BTU/SCF SG Wobbe 1207

11 SNG Advantages Available in remote locations (Bridging to build infrastructure while waiting for natural gas) Adequate supply even in peak periods (Peak Shaving) No pipelines to break (Available during natural gas outages - Back-Up) Easily stored at user site Available in remote locations (Bridging to build infrastructure while waiting for natural gas) Adequate supply even in peak periods (Peak Shaving) No pipelines to break (Available during natural gas outages - Back-Up) Easily stored at user site

13 SNG Advantages Available in remote locations (Bridging to build infrastructure while waiting for natural gas) Adequate supply even in peak periods (Peak Shaving) No pipelines to break (Available during natural gas outages - Back-Up) Easily stored at user site Available in remote locations (Bridging to build infrastructure while waiting for natural gas) Adequate supply even in peak periods (Peak Shaving) No pipelines to break (Available during natural gas outages - Back-Up) Easily stored at user site

14 Different Worlds…yet common needs…

15 CASE STUDY South Korea CityGas Development – Development of natural gas pipeline using off-grid SNG Pre- 1980s LPG Cylinder market with naptha gas in Seoul and Pusan

16 LPG SNG Start with SNG

17 Natural Gas Distribution Network R R R R PRS Gas Grid

18 LNG LPG SNG Natural Gas Arrives

19 CASE STUDY South Korea CityGas Development Mid 1980s to Mid 1990s Incheon LNG Terminal Pyeongtaek LNG Terminal Tongeyong LNG Terminal

20 Case Example So. Korea…the Results… Changed from almost no piped gas to highly developed gas system in ~15 years SNG became the temporary base fuel SNG evolved to LNG over time… Korea: 2 nd largest importer of LNG KOGAS: largest LNG buyer in world Can be Adapted to other areas

21 Where else could this model work? Ingredients for success… Problematic natural gas deliverability and good LPG availability Significant use of natural gas by both the residential and commercial sector Social / political unrest due to the energy scenario Locations where govt intervention to such problems can / will occur Possibilities: Parts of North Africa Parts of West Africa Parts of So. America Caribbean Basin South Asia Parts of Middle East

22 SNG Advantages Available in remote locations (Bridging to build infrastructure while waiting for natural gas) Adequate supply even in peak periods (Peak Shaving) No pipelines to break (Available during natural gas outages - Back-Up) Easily stored at user site Available in remote locations (Bridging to build infrastructure while waiting for natural gas) Adequate supply even in peak periods (Peak Shaving) No pipelines to break (Available during natural gas outages - Back-Up) Easily stored at user site

23 Natural Gas Usage

24 Where else could this model work? Pakistan

25 Gwadar SNG Facility

27 Pakistan Supply vs Demand

28 Pakistan Off Grid SNG benefits: A dire need… Supply chain facilities are in place (HUGE expense and time hurdle is eliminated…) Capacity is available and expandable LPG marine terminals and storage Regional LPG supply sources Political and social motivations

29 In Summary…. SNG could provide 10-20% of the current shortfall of 1050 MMSCFD quickly and cost effectively In this scenario SNG is a good fit! SNG could provide 10-20% of the current shortfall of 1050 MMSCFD quickly and cost effectively In this scenario SNG is a good fit!

42 Guidelines for Equipment Selection Analyze FULL RANGE of LPG supplies. Design equipment for worst case Equipment capacity should be determined based on lowest temperatures Select provider with ASME and UL capabilities IN HOUSE Ask about world-wide service capabilities Blender should automatically adjust to compensate for LPG quality Analyze FULL RANGE of LPG supplies.
