Abstract
Companies that require gaseous fuel that burns in their processes, show concern for the reduction of emissions of greenhouse gases, at present, 69 % of the greenhouse gases produced by the burning of the refining processes and petrochemicals, which also generated a significant environmental impact, it shows a good performance as the world leader in the field of sustainability, as measured by the Dow Jones sustainability index, which evaluates companies in economic, environmental and social. The parameters and operating conditions for the ovens are affected by the composition of fuel gas, which may be a mixture of natural gas and process gas containing methane, ethane, propane and hydrogen. The process instability due to changes in gas composition represents a risk to industrial safety, environmental issues and structural damage due to high temperatures. In order to study this problem, the baseline emission of CO2 generated was collected in ovens; CO2 historical data of the process is analyzed and the relationship established with calorific value which depended on the composition of the gas. The statistical analysis of the results and the simulation of the combustion process, determined that CO2 values have a tendency to increase when using fuels of high calorific value, which should regulate the use of mixtures containing compounds such as ethane and ethylene.
