{longname} Q618. There are differences in the applicability tool calculation spreadsheets for the estimation of vented emission from reciprocating compressor rod-packing venting. In the Transmission Compression Tool the units are "number of compressor cylinders" while in the Underground NG Storage Tool the units are "number of compressors". What is the difference and which do you think should be used? {longname} |
