Abstract
A method and system for pipeline purging with reduced environmental impact. A vacuum and/or compressor system purges air or other gases from at least a section of the pipeline to create a vacuum in the pipeline. The vacuum can then be replaced with a fuel gas, avoiding a mixing of fuel and oxidant in the pipeline. The vacuum and/or compressor system can include a fuel gas monitoring leak-detection system to monitor for fuel presence in the purging air.
