Wyetree: Design, Engineering, Manufacturing and Commissioning of Heat Exchangers
Wyetree requested preheaters for a client who provides services to the National Transmission Network and additional electricity to CFE, for the area of Mexicali BCN, where almost all the electrical energy is produced with diesel fuel.
Natural Gas is transported by pipeline to the electric system supply line for Generation Turbines at very high pressures with decreases in gas temperature at 65% of its original temperature, which was resulting in operational challenges to the equipment and distribution network.
Transom carried out the complete project management. Design, thermodynamic calculations, and installation of a new system for a 100Mw and 60Mw heat exchanger needed to raise the temperature of compressed natural gas in the pipes. Testing and verification with the ASME regulation were completed for installations in two locations, González Ortega and La Rosita in Mexicali.
Today in Mexicali, the exchangers are operating at optimal capacity at 1100 PSI with a savings of 20-30% in maintenance and fuel costs.
