ENERGY CONSUMPTION
Energy consumption in Pemex during 2004 increased to
153.2 million gigacalories -- 107.1 million barrels of
crude oil equivalent (BCOE) --, 5.8% higher than in
2003. Energy consumption in Gcal/Mton of crude oil
production or processing increased from 422.6 in 2003
to 446.0 in 2004, due to plant reconfiguration starts and
shutoffs in Cadereyta.

EFFICIENT USE AND ENERGY SAVINGS
The Energy and Environment Diagnosis Training Program
continued operating in order to identify energy efficiency
opportunities, as well as the use of tools designed by the
National Commission for the Saving of Energy (CONAE),
for follow up and results analysis.

NATIONAL AWARDS FOR THERMO ENERGY SAVING
Petróleos Mexicanos and its Subsidiaries obtained six 2004 National Awards in Thermo Energy Savings, granted
by the Energy Ministry:
Petróleos Mexicanos was granted first place under the category of Integral Programs for the design,
development and setting of the Institutional Program of Efficient Use and Energy Savings (PROENER).
Pemex Refinación was awarded first place in the “Best Practices” category, for launching a monitoring and
control system in the Refinery “Ing. Héctor Lara Sosa” in Cadereyta N.L., decreasing gas consumption in over
9,000 MMpc in the last two years.
The Refinery Ing. Antonio M. Amor of Pemex Refinación, was awarded the prize in the line of “Facilities
Modernization” by increasing efficiency of direct fire heaters in the Combined Plant “AS”.
The PGPB Cactus Gas Processing Facility, was granted two energy national awards:
In the “Facilities Modernization” category, for setting two heat recovery units leading to reduce the flaring of
gas for over 4 MMpc;
In the “Best Practices” category, for the solvent change in the gas sweetening process with economic savings
of 4.5 million pesos for the use of reagents and feedback steam.
“The Best Practices Award” was granted to the Ciudad Pemex Gas Processing Center in Tabasco, because of a
reduction in gas consumption for over 1,000 MMpc per year.

CASE STUDY
BURGOS GAS PROCESSING FACILITY
To take care of the liquid and natural gas demand, PGPB
invested 153 million dollars in the construction of the
Burgos Gas Processing Facility, which counts on a
natural gas production capacity of 380 MMpcd, 12,200
liquid gas barrels and 7,900 gasoline barrels.
Facilities comprise two cryogenic plants with a total
capacity of 400 MMpc of sweet humid gas. The
selected technological process does not consume water
and heating is performed with synthetic oil, by means of
heat recovery from exhausted gases from the residual
gas turbocompressors, reducing gas emissions to the
atmosphere.

CLEANER
PRODUCTION
Agreements of collaboration were signed between the
Mexican Center for Cleaner Production (P+L) and PEP
and PR working centers to support actions on this matter.
In the PGPB Cactus Gas Processing Center, a cleaner
production workshop was carried out wherein
opportunity areas were identified.
In PPQ, cleaner production assessments were performed
in Petroquímica Morelos, identifying improvement
opportunities in the consumption of gas, electric energy,
steam and water.
Improvements derived from the cleaner production
evaluations in the Ethylene plant (PPQ), were fulfilled with
the respective environmental and health benefits.
