About the Engineering Data Book

Approximately 260,000   copies of this authoritative publication have been distributed by GPSA. The book   has been compiled by a joint editorial committee composed of technical   specialists from both GPSA and GPA. This committee known as the GPSA Editorial   Review Board continually reviews and revises the manual. Periodic revisions are   issued to holders of record to keep the manual up to date with technology and   industry practices.

The Gas Processors   Supplier Association (GPSA) was formed in 1928 as the Natural Gasoline Supply   Men’s Association (NGSMA). Its principal purpose was a service organization to   the parent Natural Gasoline Association of America (NGAA). Both organizations   underwent name changes in subsequent years in response to changing industry   conditions. In 1961, the organizations became known as the Natural Gas   Processors Association (NGPA) and the Natural Gas Processors Suppliers   Association (NGPSA). In 1974 the names changed to Gas Processors Association   (GPA) and the Gas Processors Suppliers Association (GPSA). Users of the Data   Book will note numerous references throughout the book may refer to publications   of these organizations by the names in effect at the time of publication.
