Effect of pipe wall and crude oil temperature on wax deposition in pipeline transportation

The waxy crude oil is abundant in our country,wax deposition is a serious problem in process of oil transportation.The min-pipe flow loop experimental apparatus is set up,the wax deposition in process of transporattion is simulated.Therefore,the factors affecting the wax deposition are analyzed.The velocity of wax deposition and the temperature influence on the wax deposition are discusseded.The wax precipitating amount are calculated through experiment results.The precipitate properties are characterized by DSC.The results are meaningful for recognition of the wax deposition.It is helpful for the dewaxing and selecting pipe cleaning measures.
