Simulación Numérica del Proceso de Requemado de Gases para la Reducción de Óxidos de Nitrógeno (NOx)/ Numerical Simulation of the Reburning Technology for Nitrogen Oxides (NOx) Reduction

Estrada, Meliton ; Mendoza , Crisanto ; Romero, Carlos E
2006-01-01

Resumen en español El presente trabajo tiene como objetivo desarrollar capacidades de modelado que simulen el proceso de reducción de NOx por la tecnología del requemado de gases. En el modelo cinético construido solo se consideraron algunos de los factores que determinan la producción de óxidos de nitrógeno. La emisión de NOx procedente de la combustión del carbón mineral en generadores de vapor, es un problema ambiental importante, ya que se ha demostrado que contribuye a la form (mas) ación de la lluvia ácida y del esmog troposférico. El requemado de gases proporciona una buena opción para reducir las emisiones de NOx en instalaciones donde usan calderas a carbón. Los gases de NOx emitidos por la caldera, entran a la zona de requemado y se combinan con gas natural que es inyectado para que actúe como un agente reductor. El análisis se hace para un tiempo de residencia de 0.1 y 0.2 seg., y temperaturas de gases 1,000 a 2,000 K, con concentración de gas natural de 7.5 a 35 %. Los resultados muestran una buena equivalencia de reducción de NOx comparados con el modelo de Braun aunque se puede mejorar el modelo presentado integrándolo con un modelo detallado de la mecánica de fluidos turbulenta Resumen en inglés The aim of this work was to develop modeling capabilities which could be used to simulate the processes of reduction of NOx in reburn technology. The kinetic model developed in this work considers only some of the factors that contribute to nitrogen oxide production. Emission of NOx from the combustion of coal is an important environmental problem, since it has been demonstrated that it contributes to the formation of the acid rain and of tropospheric smog. Gas reburning (mas) is a useful option for the reduction of emissions of NOx in installations equipped with coal-fired boilers. Gases from the boiler containing NOx, enter a reburning zone and are combined with natural gas that is injected in order to act as a reducing agent, which transforms the NOx into N2. Analyses were done for residence times of 0.1 and 0.2 sec., at a range of temperatures between 1,000 - 2,000 K, and natural gas concentration from 7.5 - 35 %.The results show that good agreement with those of Braun although the model could be improved integrating it with a detailed turbulent fluid mechanic model

Resumen en español El presente trabajo se basa en el estudio de la producción de carbón activado a partir de carbón mineral subbituminoso en un reactor de lecho fluidizado por proceso autotérmico. El carbón utilizado provino de la región de Amagá (Antioquia - Colombia) y fue activado en dos reactores de lecho fluidizado de diferente diámetro interno, 10 cm y 22 cm. Los valores del área superficial específica y el volumen de poro de las muestras activadas fueron determinados a part (mas) ir de las isotermas de N2 y CO2. Los resultados experimentales mostraron que los valores de áreas superficiales BET y DR y del Índice de Yodo se encontraron alrededor de 460 m²/g (S BET), 490 m²/g (S DR) y 460 mg I2/g carbón. Resumen en inglés This work is based on the activated carbon production from coal by physical activation in a fluidized bed reactor by an autothermal process (without an external energy source). Coal from Amagá region (Antioquia - Colombia ) was activated in two fluidized reactors, 10 and 22 cm of diameter. The specific surface area and pore volumes values were determined by gas adsorption of N2 and CO2. Experimental results revealed that the BET and DR surface areas and Iodine Number values oscillated near to 460 m²/g (S BET), 490 m²/g (S DR) y 460 mg I2/g carbon.

Resumen en español Se evalúa económicamente la utilización de la tecnología de gasificación de carbón en la generación de energía eléctrica, utilizando información secundaria y el enfoque de valoración de opciones reales mediante árboles binomiales de 2 variables. Se analiza el caso de adaptar una central existente de gas natural de ciclo combinado (NGCC) para la utilización de syngas a partir de carbón; en un segundo caso, se evalúa la instalación de una nueva central termo (mas) eléctrica de carbón pulverizado (PC) o alternativamente una central de gasificación de carbón integrada a ciclo combinado (IGCC). En este último caso, se evalúa la opción de "switching" de combustible. Para los precios de los combustibles se emplean modelos de Movimiento Browniano Geométrico No Homogéneo (IGBM) y en ambos casos estudiados se analiza en 2 escenarios de precios, incluyendo análisis de sensibilidad. Respecto al primer caso, la adaptación a syngas de una planta NGCC es conveniente económicamente, teniendo el proyecto una alta sensibilidad respecto a la eficiencia. La sensibilidad a la inversión no es significativa, como tampoco a los gastos de operación. Respecto al segundo caso, la conveniencia económica de la planta IGCC frente a la planta PC no es clara en los escenarios de precios considerados. Pero analizada en diversas combinaciones de precios, la planta IGCC de operación flexible alternando dos combustibles puede lograr ventajas económicas. Respecto a la sensibilidad, se repiten las conclusiones mencionadas para el primer caso Resumen en inglés The use of coal gasification technology in the generation of electric power is evaluated economically. Secondary information and valuation of real options approach is used, with two variables binomial lattices. First, the retrofit of an existing natural gas combined cycle plant (NGCC) for the utilization of syngas from coal is analyzed; on the second case, an economical evaluation is realized for to compare a new Pulverized Coal plant (PC) and, alternatively, an Integrate (mas) d Gasification to Combined Cycle plant (IGCC). In this last case, the fuel switching option of the IGCC plant is analyzed. For the fuel prices, Inhomogeneous Geometric Brownian Movement processes are used. In both cases, two prices scenarios are considered with sensitivity analysis. Regarding the first case, adaptation to syngas in a NGCC plant is economically desirable, having the project a high sensitivity to efficiency. The sensitivity about investment is not significant, nor to the operating expenses. Concerning the second case, the economic convenience of the IGCC plant in front of the PC plant is not clear in the price scenarios considered. But analyzed in various combinations of prices, flexible operating IGCC plant alternating two fuels can achieve economic advantages. With regard to the sensitivity, conclusions mentioned in the first case are similars for the second case

Resumen en inglés Background: Indoor pollution can be an important risk factor for human health, considering that people spend more than 60% of their time in their houses. Aim: To investigate indoor pollution in a zone of extreme poverty in Metropolitan Santiago. Material and methods: During 24h, carbon monoxide (CO), sulfur dioxide (SO2), respirable particulate matter (PM10), polycyclic aromatic hydrocarbons absorbed in PM5, temperature and humidity, were measured in the interior of 24 ho (mas) uses in La Pintana, Santiago. Results: The higher pollutant concentrations were observed during hours when heating was used, in houses that used coal (mean PM10 250 µg/m3, CO 42 ppm, SO2 192 ppb) or firewood (mean PM10 489 µg/m3, CO 57 ppm, SO2 295 ppb). In all houses, polycyclic aromatic hydrocarbons were detected and they came from the interior of the house and not from external filtered air. Coal, firewood and cigarette smoke were important sources of carcinogenic and kerosene and gas were sources of non carcinogenic polycyclic aromatic hydrocarbons. Conclusions: In the houses studied, the population was exposed to an accumulation of highly toxic pollutants, caused by a lack of ventilation. A high relative humidity also contributed to the growth of biological pollutants (Rev Méd Chile 2001; 129: 33-42)
