摘要:
Investigations at natural gas fields as well as modelling experiments have pointed out that changes of the chemical and isotopic composition occur in the course of migration, accumulation and dispersion of natural gas. Dissolution and sorption processes as well as in particular the diffusion process come into consideration as elementary processes of the separation. The influence on dissolved and freely flowing gases and on stationary gas accumulation are described by differential equations. The simulation of the following phenomena are shown:
