Annomalies

- Clearstone II (After De-Methanizer) Open Ended Lines: centrifugal is greater than reciprocating because there are only three data points for centrifugal compressors. - Clearstone II (Before De-Methanizer) Connectors: non-compressor is greater than compressor emissions because molecular sieve, NRU, and Amine building emissions are large. - Clearstone II (Before De-Methanizer) Meters: non-compressor is greater than compressor emissions because there is only one co mpressor data point and four non-compressor data points. - Clearstone II (After De-Methanizer) Open Ended Lines: non-compressor is greater than compressor emissions because there are s ome large emissions from generators and flare vents.
