Patent number: 8313568Abstract: An off gas extraction system provides superior results to other systems for cleaning polluted soil. Off gas is extracted, followed by compression and condensation. Compression and condensation produce an off gas that must be further treated to produce pollutant-free exhaust. A regenerative adsorber cleans the influent gas/air by adsorbing residual chemical vapor and concentrates the removed chemical vapor and reprocesses them. Conventional scrubbers are used on the back end of the system to produce a final exhaust as prescribed by environmental regulation. Methods of accomplishing the same are similarly provided, including unique business methods for conforming extraction plans with current environmental regulations and compliance impact generation based on an evolved knowledge base.Type: GrantFiled: December 28, 2009Date of Patent: November 20, 2012Inventor: Carol Diane Krumbholz
