Study on Pigging Process Analyses and Control Methods for Moisture Gathering Lines: Study in Puguang Gas Field, China

The moisture gathering line of the Puguang Gas Field in China renders it prone to accumulating liquid at certain points due to topographic differences. Under operational conditions of pigging, liquid slug volumes, end drainage rates, and production separator surge volumes increase. Multiphase flow transient simulation software is used to study the P102 gas gathering station pigging process. The purging gas volume was measured to be 650×104...
