Breston [57] ABSTRACT A process and apparatus for dehydrating a pipeline by using a pig propelled through the pipeline with compressed, water-absorbing, oil-free air generated by a portable dry air generating plant positioned near the pipeline. 2 Claims, 3 Drawing Figures SEPARATOR DESICCANT TOWERS TIMED VALV E CONTROL PATENTED FEB 41975 SHEET 2 BF 2 FROM FILTER FIG.3. DEIIYDRATION OF A PIPELINE WITH A PORTABLE DRY AIR GENERATING PLANT BACKGROUND OF THE INVENTION Various pipeline pigs for removing liquids from pipe lines are known. Pigs which are now widely used throughout the industry are described, for example, in applicant's US. 3,643,280 and 3,659,305. In- use, a gas under pressure propels the pig through the pipeline and water or other liquid in the pipeline is absorbed by the gas or moved by the pig downstream. The only two gases that have been commercially available and are dry enough for pipeline drying are nitrogen and natural gas. When new pipelines are tested they are frequently subjected to a hydrostatic test. After such test it is necessary that most of the tested pipelines be well dried before hydrocarbon fluids can be sent therethrough. When hydrocarbon fluids such as combustible gases, oils, gasoline, etc., are sent through an improperly dehydrated pipeline, they are likely to become rejected by the consumer for containing an excessive amount of moisture. As a result, pipeline operators spend considerable effort and money in making certain that substantially all of the water in the pipeline is removed prior to sending hydrocarbon products through the pipeline. Several passes through the pipeline must be made with the pig in the expectation that each such pass will remove a portion of the still remaining moisture in the pipeline. But even after a great number of pig passes, there is still no assurance that substantially all of the water will be removed from the pipeline. Divx saw rebirth cartoon characters. Pockets and- /or films of water frequently remain in certain sections of the pipeline and their existence manifests itself only after an analysis is made of a fluid that has passed through the pipeline. It is a general object of this invention to dry a pipeline by pushing a pig with non-poluting dry air which has the ability to absorb moisture. This invention eliminates the need for expensive nitrogen and/or precious natural gas. SUMMARY OF THE INVENTION BRIEF DESCRIPTION OF THE DRAWINGS FIG.
