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.
