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.
Claims20
A method for pipeline purging, the method comprising:
- creating a vacuum within at least a section of the pipeline;
- and
- filing the vacuum with a fuel gas.
A system for performing a purge of a pipeline, the system comprising:
- a vacuum and/or compressor system configured to connect with the pipeline;
- a monitoring system connected with respect to the pipeline and the vacuum and/or compressor system to identify leaks and/or concentrations of fluids within the pipeline and/or concentrations of fluids within the vacuum and/or compressor system;
- identification of one or more prescribed vacuum states;
- and
- an interlock to isolate samples for the monitoring system.
