Abstract
A mobile compressed natural gas (CNG) vessel and unloader are used to supply CNG to a compressor during regulatory emissions testing of the compressor (e.g., U.S. EPA's Quad J testing). CNG output by the compressor is recirculated to an inlet of the unloader so that it is reused during the emissions testing. Lean CNG from the vessel may be used to power the compressor during the testing. The unloader ensures that the compressor is run at at least a predetermined load factor during the emissions testing.
