Estimating Erosion in Oil and Gas Pipe Line Due to Sand Presence

University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

Abstract:

Transporting solid particles in oil and gas flow cause erosion damage to the pipeline and fittings. The aim of this thesis is to study the effect of impact velocity on the erosion damage in 90 degree long elbow by using two different erosion models namely, Oka model and E/CRC model. Those correlation applied at air-borne sand eroding, methane-borne sand eroding, mixed gas-borne sand eroding, and multiphase (gas- oil) borne sand eroding Inconel 625. The commercial computational fluid dynamics (CFD) code STAR-CCM+ is used to obtain the average and maximum erosion rate by using the above mentioned models and compared them with the previous results.
