7. Natural Gasoline Streams

8. Natural Gasoline Streams • “Naphtha” is a generic term used in Mexico for natural gasoline. • Mexico’s natural position is long. • Mexico remains as one of the main exporters of natural gasoline in the world. • Mexico’s natural gasoline streams are: 1) “Cactus Naphtha” 2) “Burgos Naphtha” (formerly known as “Reynosa Naphtha”) Burgos Naphtha comes from the Burgos Gas Processing Center in the Northeast region of Mexico next to the U.S. border. Cactus Naphtha comes mainly from the Cactus, Nuevo Pemex and Ciudad Pemex Gas Processing Centers, in the Southeast region of Mexico

9. Cactus Naphtha Specs • Cactus is well known as a petrochemical feedstock mainly used for cracking… • Cactus specs are:

11. Cactus Naphtha Logistics • A closer look on Cactus logistics… • Overall production: 88 kbd • Volume for export: 70 kbd • Volume for domestic use (petrochemical): 18 kbd • Transported from Gas Processing Centers to Pajaritos Terminal on the Gulf of Mexico • From Pajaritos, shipped waterborne to destination ports in USGC and other regions in the world La. Tx. Main destination areas 2-day voyage Pajaritos (Little Birds) Gas Processing Centers

12. Burgos Naphtha Specs • Burgos is a stream coming from both Burgos and Reynosa plants. It may be used either as a petrochemical feedstock or even gasoline blendstock due to its low sulfur content… • Burgos specs are:

13. Burgos Naphtha Logistics • A closer look on Burgos logistics… • Overall production: 9 kbd (expected to increase up to 20 kbd towards 2010) • Volume for export: 9 kbd • Transported from Burgos Gas Processing Center to Brownsville by pipeline and trucks • From Brownsville, shipped waterborne by barge to destination ports in the U.S. La. Tx. Main destination areas Brownsville Burgos Gas Processing Center

14. N+A Naphtha • Pemex Refining still produces about 36 kbd of N+A naphtha at La Cangrejera complex in Veracruz. • Almost all N+A produced goes to the BTX plant that Pemex Petrochemicals owns at the same complex La Cangrejera. • The rest of the N+A produced goes to Pemex Refining for refining processes. • Sometimes Pemex Refining sends product to other refineries, but that is rare. • The BTX plant at La Cangrejera has a total capacity of 45 kbd so it is still necessary for Pemex to import product. • PMI has importing roughly 9 kbd of N+A naphtha since 2006. • The main specifications for N+A naphtha required by Pemex are:

16. Forecasts Natural Gasoline • The forecast for Natural Gasoline Production (Cactus + Burgos) is shown below in kbd N+A Naphtha • Pemex Refining is expected to maintain its production of N+A naphtha in 36 kbd through the year 2010. • Pemex Petrochemicals is expected to need 45 kbd in order to keep its BTX plant running at capacity. Imports of N+A should continue though quota may decrease. Source: Pemex-Gas y Petroquímica Básica

41. NGL’s Projects

42. Burgos Project • The Burgos Gas Processing Center started operations in August 2006 • 2 cryogenic plants of 200 mcf each • One condensate stabilization section of 6 kbd • Total capacity: 17 kbd • Storage capacity: 40 kbd for LPG, 25 kbd for naphtha • Truck rack: 6 trucks/hour • Current production: 11.5 kbd of LPG, 9 kbd of natural gasoline, 380 mcf of dry gas Source: Pemex

43. Fénix Project • Original Fénix Project has been redifined. • PEMEX is focusing on extending already-existing facilities and infrastructure at petrochemical complexes in Veracruz. • The building of a brand-new cracker has not been confirmed. It is unlikely within the next few years. • Alternative plans for Fenix Project may include: • Separation of C5’s from C6+ • Use of C6+ for petrochemical purposes • Potential exports of Pentanes • Potential isomerization of Pentanes • Potential normalization of Pentanes • No official announcement about any Fénix development has been given yet by PEMEX or the Mexican government.

44. Conclusions

45. Natural Gasoline and Naphtha Conclusions • Mexico will continue to be a net exporter of Natural Gasoline. USGC will continue to be the main destination. • Natural Gasoline exports may reach over 70 kbd in following years. • Cactus will remain as the most widely available Natural Gasoline stream from Mexico. • Burgos naphtha availability should slowly increase within next few years. Logistics for transportation and marketing may include use of pipelines, trucks, barges and vessels. • Burgos naphtha could become an attractive component for gasoline blending in the U.S. under increased gasoline demand conditions and sulfur restrictions. • Mexico may import less N+A naphtha in coming years due to change in crude slate for domestic petrochemical units.

46. LPG Conclusions • Mexico will continue to be a net importer of LPG, even with less domestic demand. • Mexico will continue to play a key role as a buyer under the scenario of upcoming new worldwide production. • Waterborne vs. inland imports will vary depending on the economic incentives and strategic projects to attract supply from different sources. • LPG in Mexico will continue to compete against alternative fuels like LNG, natural gas, wood and coal. • Mexico is still the highest LPG per capita consumer in the world and it is expected to import product at least through 2010. • LPG supply is a key social aspect in Mexico. It will continue to be for the coming years.
