1. A device comprising, in combination:
at least one off gas extraction source;
a vacuum and compression module; and
a vapor elimination module comprising:
at least one condensation module to condense fluid from off gas;
a regenerative adsorbing module having a plurality of adsorbers;
wherein each adsorber adsorbs pollutants from a high pressure gas and desorbs the pollutants into a low pressure gas;
