Transport characters of waxy crude oil pipeline & outlook of the natural gas pipeline in China 12/09/06 ; 26/08/2003 3 p. Resumen del autor, extraído del trabajo. The special rheological properties of waxy oil, appearing in a certain limited temperature rang, lays a rheological foundation bettering its low-temperature fluidity, and a series of specialized measuring techniques make it possible to obtain the accurate flowing parameters of waxy oil. The development on constitutive equations, and mathematical mode/software have pushed forward the pour point depressant (referred to PPD) technology to a general utilization in pipelines. Up to present, more than one dozen of pipelines have been under operation with the technique conducing safety and economy. Also, this technique has been successfully used in Sudan oil pipeline. Natural gas has gained an ascending proportion in buildup of energy consumption worldly. Chinese government has accordingly drawn up the relevant policy to promote gas industry. Most gas consumers are now in industrial cycles such as chemical and power supply etc. The gas consumption for civil use only accounts for a small portion. Now most of gas fields located in west of China, but the main gas user lie in east. The 10000-km gas trunk pipeline in existence is just at the initial stage. Base on the marketing trend and gas resources, China has worked out an ambitious plan to meet the requirements. v. 4, p. 235 ARCHIVO Gao, Tangui 10095 Quan, Zhongyu 10096 Zhu, Baoli 10097 Xu, Cheng 10098 Pipeline Corporation 10099 Petrochina 10100 World Petroleum Congress (16th. : 2000 jun. 11-15 : Calgary, Alberta, Canada) 34 Quan, Zhongyu 10096 Zhu, Baoli 10097 Xu, Cheng 10098 Pipeline Corporation 10099 Petrochina 10100 Gao, Tangui 10095 133656 133656 0 0 0 0 204575 BAAB BAAB CD W938 1 0013960 2026-03-04 200006163 0 CD W938 1 0013960 200006163 2026-03-04 14:03:33 2026-03-04 ARCHIVO
