GONZALEZ-ROCHA, J.C; LONGORIA-RAMIREZ, R  and  URQUIZA-BELTRAN, G. Results of the simulation of gasification of the mexican petroleum coke from the refineries of Ciudad Madero and Cadereyta. Ing. invest. y tecnol. [online]. 2008, vol.9, n.2, pp.99-111. ISSN 2594-0732.

This paper evaluates in terms of energy the gasification of the petroleum coke from the refineries of Cd Madero and Cadereyta in Mexico. The energy evaluation of the synthetic gas (syngas) focuses mainly on the chemical composition of the clean syngas (gasl) and its energy characteristics: heating value, the energy power, the cold gas efficiency and the thermal efficiency of gasification. The results of the simulation indicate that the gasification of the petroleum coke from Cadereyta called CRC, produces a gasl with better performance and energy characteristics than those obtained when gasifying the coke of petroleum from Cd. Madero, called CRM. When the CRC is gasified, the rate of production of gasl obtained is of 2.07 kg_gasl/kg_coque, while the rate of production of gasl for the CRM is 1.89 kg_gasl/kg_coque. The HHV of the gasl of the CRC is 12 729.56 kJ/kg_gasl while for the CRM is 11 639.13 kJ/kg_gasl. The energy power of the gasl of the CRC is greater, with a difference of 25.87 GJ/h, with regard to the energy power of the gasl of the CRM. Under the specified conditions of operation, energy is generated ata rate of 26.46 MJ/kg_coque coke in the gasification of the CRC coke of petroleum, while when gasifying the CRM coke of petroleum 22.09 MJ/kg_coque are generated. Currently, the petroleum coke produced in the refinery of Madero is consumed in the power plants of Tamuín, San Luis Potosí, Mexico, while the petroleum coke produced by the refinery of Cadereyta is used in the cement industry.
