Advanced progresses in nature gas pipelining applying different drag reduction/energy saving technologies: a review

Abstract

Energy conservation and environmental protection has progressively developed into the hot and popular topics in nowadays. In the process of natural gas transmission, almost all the power of the compressor stations has been used to overcome the friction consumption between the flowing gas and pipeline wall, so large numbers of resources are spent on the maintenance of the pumping stations every year. How to reduce the wall friction and increase the transportation output has been becoming the urgent problem to be resolved. Internal smooth coating, injecting nano-chain drag reduction agent and bio-inspired drag-reducing morphology have been gradually taken into application in the past several decades, and the field testing results were all striking and satisfactory. An overview of applying different drag reduction technologies into nature gas pipelining is systemically presented in detail, which has the important significance to understand research status and development tendency of nature gas industry.

Drag Reduction by Polymer Additives: State-of-the-Art Advancements in Experimental and Numerical Approaches

“…With regard to the research interests and subject areas, most documents were published in engineering, physics astronomy, and chemical engineering journals, as shown in Figure S1 of the Supporting Information. Mainly, this is related to the urgent need to reduce the drag in turbulent flow in engineering applications such as hydraulic fracturing. , The research was mainly focused on mechanisms, materials, affecting parameters, challenges, and experimental, mathematical, and numerical approaches used to analyze the DR. ,,,− Most of these investigations were conducted on the pipe flow systems.…”

Thriving artificial underwater drag-reduction materials inspired from aquatic animals: progresses and challenges

“…During pipeline transportation, coatings, biomimetic microstructures, and injecting nano-chain drag reduction additives have been applied and have achieved good results. 197 Both the compliant coating stimulated by dolphins and the shark scales-like microstructure surface has been tested by a variety of methods to verify its practicality. And, the use of the drag-reducing additive has more potential due to the super-efficient drag reduction rate in pipeline transportation.…”
