Energy Efficiency

Installation of a cogeneration plant with the use of steam from the catalytic cracking process in tubular reactor to increase the energy efficiency of the industrial unit. Have been installed new demineralization units for water treatment in the inlet pipes of the boilers that are in the Utilities Central. Boilers steam turbogenerators trigger that distributes power to three substations connected to the auxiliary input substation with 4 transformers of 25MVA-138kV / 13.8kV and controlled by EPMS for disposal loads at a time that there is peak demand. Substations are supervised by the IEC 61850 network inside the control room located in the central building of utilities.
It was necessary to replacement of the control and protection of turbines and generators exchange and adequacy of synchronization systems and the replacement and refurbishment of field instrumentation to implement the new system. The contingency analysis algorithm analyzed the consumption of critical loads in the electrical system enabling the load shedding system test. The system has 88 hours under test with the total demand of the plant operation sharing all electrical loads. Several operations were made with medium voltage circuit breakers in substations through the supervisory system in the Operation Control Center. Electromechanical assembly in axial condensers were used to reduce losses at the entrance of the turbines and increase energy efficiency of the cogeneration unit.
