DNAPL szennyezések transzportmodellezési lehetőségei a GMS programban

Abstract

The chlorinated hydrocarbons belong to denser water-chemicals. Except to the subsurface geological features the behaviour of chlorinated hydrocarbons may be considered their chemical, physical, chemical characteristics, influence, these are not limited to density, kinematic viscosity, surface tension, chemical composition, solubility in water and other solvents, vapor pressure, Henry constant and wetting in the transport modelling. The difficulty is that it is not so easy to find such information from DNAPL. In our research we used the Groundwater Modelling System (GMS). For modelling we used the next two modules: UTCHEM: Utchem is a module of the GMS. The module was developed at the Center for Petroleum and Geosystems Engineering at the University of Texas at Austin as a chemical flood simulator for enhanced oil recovery design. In recent years, Utchem has been adapted for a variety of environmental applications as well. SAEAM3D: A reactive transport model used to simulate complex biodegradation problems involving multiple substrates and multiple electron acceptors.
