The Institute is able to provide consulting on the analysis of the effects of earthquake and wind on

industrial structures, as well as on the design of transmission and distribution towers, electric

power substations, chimneys, dams and others which has helped the Institute to become one of the

main groups dedicated to the analysis and design of specialized structures within the national electric power

sector.

20

Our most recent contributions include updating the chapter on earthquake design in the civil works design

manual of the Comisión Federal de Electricidad, which will continue to be the mandatory reference for the

development of civil engineering projects in the country, as well as for training the new generation of civil

engineers in Mexico.

We updated procedures for wind design of structures and transmission line systems, and the design of electric

power substations for wind and earthquakes. The application of this will have immediate economic and

safety benefits for civil works that have already been designed and great impact on electric power transmission

allowing companies to obtain more reliable substations and support structures for transmission lines.

The institute carried out an assessment of civil works to remove obstructions from the Xaltepuxtla River to

protect the Tepexic Hydroelectric Power Plant belonging to the electricity company Luz y Fuerza del Centro

(LyFC).

Projects

• Updates to the chapter on earthquake design in the civil works design manual of

the Comisión Federal de Electricidad, second part.

• Updating of criteria and coefficients for the chapter in wind design in the civil

works design manual (MDOC by its initials in Spanish).

• Updates to criteria for calculating mechanical loads on transmission lines and electric

power substations.

• Assessment of civil works to remove obstructions from the Xaltepuxtla River to

protect the Tepexic Hydroelectric Power Plant.

Materials

and Chemical Processes

The Institute has the technical capacity to provide services related to the application, diagnostic and control of degradation of polymeric and

metallic materials.

Our contributions to the energy sector are the result of research and the application of the technologies developed to increase the quality and reliability of

different processes and products.

The IIE developed methodologies for the electric power sector to characterize synthetic insulators and its expected behavior in the field, as well as supported

the review and drafting of reliable specifications for the acquisition, handling and application of synthetic insulators according to geographical conditions

in Mexico. The IIE also developed methodologies for diagnostics to allow assessment of the operational status of insulation systems in primary substation

equipment for the purpose of reducing indices of failures and maintenance costs.

For the oil industry we carried out a study on the integrity of underground pipeline coverings, location and severity of defects, and an analysis of the distribution

of impressed current to allow optimization of cathodic protection systems. Likewise, we gave training courses on Direct Current Voltage Gradient

techniques (DCVG) in order to train and certify PEMEX personnel to levels I and II.

Finally, and in order to offer the latest technology for understanding the status of cathodic protection in underground pipelines, the IIE developed sensors

for monitoring corrosion rate and a wireless network of sensors to monitor corrosion potential in underground pipelines.

Projects

• Development of methodologies and assessment criteria for synthetic insulation

exposed to the weather in Electric Power Substations.

• Development of diagnostic techniques for power transformers through assessment

of moisture content and its effects of the dielectric properties of oil/paper insulation

systems.

• Conservation and Distribution of Cathodic Protection Systems in Pipelines at the

Dos Bocas Marine Terminal.

• Wireless network to monitor cathodic protection in underground pipelines.

Thermal Processes

The Institute evaluates the behavior of equipment and systems of power plants and steam generators, as well as the

redesign of components in electric power generation and industrial plants using its especially trained personnel for this

purpose. We also develop and apply generation and cogeneration schemes which translate to energy and economic savings.

Our most recent contributions include precise analyses of the status of units 3 and 4 at the Francisco Perez Rios Thermoelectric

Power Plant in Tula, Hidalgo. We also carried out a project for the Subdirectorate for Project Development of the CFE to analyze

alternative technologies and fuels for use in power generation in order to meet the demand for electricity opportunely, efficiently

and at lower cost.

We carried out a number of different technical-economic feasibility studies for Pemex Refining so as to establish strategies for

primary services that will allow its refineries to comply with NOM 085 for the reduction of sulfur content in fuels. Likewise, we

developed a study in collaboration with the Mexican Petroleum Institute that will allow us to make decisions related to establishing

cogeneration schemes and the use of coke at the Salamanca refinery so that together with the CFE, they generate greater energy,

economic and environmental benefits.

Projects

• Technical-economic feasibility study, conceptual engineering, user bases and steam

balances, electric power and steam headers to cover the primary services for new

clean fuel plants at the Salina Cruz refinery.

• Assessment of heat distribution in the ash box and furnace of Unit 3 at the Francisco

Perez Rios Thermoelectric Power Plant, and analysis of the microstructure of

the material used in inferior headers.

• Analysis of alternative technologies and fuels for consumption by the CFE.

• Provide support to the Mexican Petroleum Institute in analyzing options for exploitation

or disposal of coke at the Salamanca Refinery and Thermoelectric Power

Plant in order to ensure compliance with the City’s environmental standards.

The Institute’s activities in the area of turbomachinery include the development

of methods and tools for diagnosing faults and refurbishing and extending

the useful life of turbomachinery components, specifically in steam,

water and gas turbines, as well as in important auxiliary equipment, which includes

compressors and pumps at electric power generation plants.

The IIE supported Comisión Federal de Electricidad by identifying the potential

capacity for energy exploitation of the exhaust from seven 5 MW steam turbines

installed at the Los Humeros geothermal field. Likewise, we estimated the cost of

investment needed to exploit this energy and drafted the specifications of the tender

for the project.

23

Furthermore, we followed up on the results of the recommendations made by the Institute for eliminating the high vibrations

recorded in the turbogenerator of unit 4 at the Valle de Mexico thermoelectric power plant.

Additionally, we drafted the first eight chapters of the Procedures Manual for Maintenance and Refurbishment of Main Components

in Steam and Gas Turbines, which will assist the CFE put the tasks of refurbishment and maintenance out to tender, and

ensure the quality of the work.

Finally, we provided support to the electricity company Luz y Fuerza del Centro in supervising testing carried out during introduction

into service of nine new electric power generation plants employing gas turbines installed by the General Electric company. The

project included supervision of acceptance testing in order to guarantee compliance with specifications laid out in the agreement

under which the generation plants were acquired.

Projects

• Technical collaboration to carry out the study on efficient energy use at the Los

Humeros geothermal field, Puebla.

• Technical support for the bidding process for the Humeros II project.

• Follow up to the recommendations for diagnosing and correcting high vibrations

in the TG-4 turbogenerator at the Valle de Mexico Thermoelectric Power Plant.

• Development of specifications for maintenance and refurbishment of main components

in turbomachinery.

• Technical supervision of start up and operational testing of fourteen 32 MW

turbo gas electric power generators installed in the State of Mexico and the Federal

District.
