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.
Claims9
A process for capturing pigging emissions in a natural gas pipeline, the process comprising:
- processing a product of a pigging system, wherein the product comprises a fluid removed from the natural gas pipeline in a pigging operation;
- sending the processed product a compressor;
- compressing the processed product;
- and
- inserting the compressed product into the natural gas pipeline to recombine the compressed product with a gas stream flowing through the natural gas pipeline.
