AN ALTERNATE METHOD TO PREVENT SAND ABRASIVE EROSION IN PIPELINES FOR TRANSPORTING HIGH-SPEED NATURAL GAS

摘要

This paper presents an alternate method to re- move the sand carried by natural gas in the upstream pipelines therefore preventing sand abrasive erosion in pipelines used in transporting high-speed natural gas. Conventionally, most ex- perts pay much attention to improving the anti-erosion charac- teristics of the pipeline materials to solve the problem of seri- ous abrasive erosion, but without significant success. Based on the theory of multiphase flow and analysis of the character- istics of sandy jets, a new equipment named "Sand Catcher" introduced in this article. Experimental results show that the Sand Catcher effectively removes most of the sand in the natu- Ral gas and significantly reduces the abrasive erosion of the Pipelines. The Sand Catcher can be widely applied din practice In the near future.
