Das Verlegen und Verbinden von Kabeln,at will result in pollution. This method, however, cannot be applied. Anthropogenic activities cannot be separated from einvironmental pollution. But man can reduce and change his activities such that pollution can be held below a critical threshold value so that the environment can take care of the pollutants without being endangered.

Design and Operation of Adsorption Equipment,ion control the relevant gases and vapors are the pollutants which have to be separated from an inert gas stream emitted into the ambient air. Adsorption therefore is a useful means of concentrating the pollutants, this facilitating their disposal or recovery.
