In order to calculate the wax deposition rate of crude oil pipelines and discuss its regularity, a pseudo-three-dimensional wax deposition numerical model was established based on computational fluid dynamics and heat transfer theory. The model…
In this paper, wax deposition in waxy crude oil transportation process was regarded as an irreversible process. Based on the entropy production rate equations, the linear phenomenological equations for the diffusion of wax molecules were derived by…
Solvent bitumen extraction processes are alternatives to thermal processes with potential for improved economic and environmental performance. However, solvent interaction with bitumen commonly results in in situ asphaltene precipitation and…
