In the field of practical engineering, saving energy, reducing energy consumption and adapting to the international oil situation are the development trends and represent difficult problems. Based on the basic principle of non-equilibrium thermodynamics, this paper derives the field equilibrium equations of non-equilibrium thermodynamic process for pipeline transportation. To seek the bilinear form of \u201cforce\u201d and \u201cflow\u201d in the non-equilibrium thermodynamics of entropy generation rate, the oil pipeline exergy balance equation and the exergy transfer pipeline dynamic equation of the irreversibility were established. The exergy balance equation was applied to energy balance evaluation system, which makes the system more perfect. The exergy flow transfer law of the waxy oil pipeline were explored deeply from the directions of dynamic exergy, pressure exergy, thermal exergy and diffusion exergy. Taking an oil pipeline as an example, the influence factors of exergy transfer coefficient and exergy flow density were analyzed separately.<\/jats:p>","DOI":"10.3390\/e20050309","type":"journal-article","created":{"date-parts":[[2018,4,25]],"date-time":"2018-04-25T03:22:45Z","timestamp":1524626565000},"page":"309","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Studies on the Exergy Transfer Law for the Irreversible Process in the Waxy Crude Oil Pipeline Transportation"],"prefix":"10.3390","volume":"20","author":[{"given":"Qinglin","family":"Cheng","sequence":"first","affiliation":[{"name":"Key Lab of Ministry of Education for Enhancing the Oil and Gas Recovery Ratio, Northeast Petroleum University, Daqing 163318, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anbo","family":"Zheng","sequence":"additional","affiliation":[{"name":"Key Lab of Ministry of Education for Enhancing the Oil and Gas Recovery Ratio, Northeast Petroleum University, Daqing 163318, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuang","family":"Song","sequence":"additional","affiliation":[{"name":"Key Lab of Ministry of Education for Enhancing the Oil and Gas Recovery Ratio, Northeast Petroleum University, Daqing 163318, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hao","family":"Wu","sequence":"additional","affiliation":[{"name":"PetroChina Planning &amp; Engineering Institute (CPPEI), Daqing 163318, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lili","family":"Lv","sequence":"additional","affiliation":[{"name":"PetroChina Planning &amp; Engineering Institute (CPPEI), Daqing 163318, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7320-5344","authenticated-orcid":false,"given":"Yang","family":"Liu","sequence":"additional","affiliation":[{"name":"Key Lab of Ministry of Education for Enhancing the Oil and Gas Recovery Ratio, Northeast Petroleum University, Daqing 163318, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,4,24]]},"reference":[{"key":"ref_1","first-page":"6","article-title":"Exergy transfer analysis for thermal oil pipeline process","volume":"4","author":"Cheng","year":"2005","journal-title":"J.
