Abstract

necessity of the country's space development and moving towards the launch of earth satellites, the use of high-power propellants such as nitrogen tetra oxide N2O4 is essential. necessity of environmental assessment has been taken into consideration and it has been stated that all plans must have an environmental assessment. , according to the purpose of the research and research, the emission radius related to the opening of the vent valve from N2O4 tanks of the AVUM system, Finally, the method of reducing the surface adsorption method was chosen. In this method, in order to preserve the environment and use the available resources properly, among the inexpensive absorbents, fennel seeds and eggshells, very cheap absorbents, eggshells were investigated and finally, in order to reduce 92.1% of the target gas emission radius of the eggshell was chosen due to its high absorption percentage, and then the length of the absorber was calculated.
