Abstract
Disclosed are processes, apparatuses, and systems in natural gas pipelines to significantly reduce pigging and blowdown emissions. In an example, a process involves filtering and/or separating pigging or blowdown emissions. The filtered and/or separated pigging/blowdown products can then be stored in a storage, sent back into the natural gas pipeline at a downstream location, or sent to an adjacent pipeline.
