液环输送渣油的试验研究

Core-Annular Oil Residue/Water Flow Tests,

本文叙述了管道中用液环方式输送粘稠油品的机理。渣油在管道的液环中是流动的内核,核流的外面为层流流动的低粘度液体环,并与流动核保持同心。结果表明,这是渣油输送的较经济的方法。文中还讨论了影响液环流动系统的各种因素。

The transportation of residue oil from refinery plant is investigated by using two adjacent immisible liquid flow concept. The resid in the form of laminarly flowing core is jacketed by a low viscous fluid which flows laminarly and eccentrically around the resid core in a pipe. The results obtained proved to be an economic method for residue oil transportation. The selected factors that effect the flow system are discussed.
