L22277 Retrograde Condensation in Natural Gas Pipelines
Author(s): Bergman, Tek, Katz
The natural gas pipeline industry had an increasing number of interruptions or interference of flow by natural gas due to the presence of condensates in the pipelines. Frequently the customer or the distributing pipeline operating at lower pressures is the recipient of the liquid condensate reaching them sometime in the late fall or winter during a period of high demand for natural gas. This project investigated the causes of the formation of liquid hydrocarbons, ways to predict when condensates will form, and preferred methods of condensate removal when formed inadvertently.
