PROPAGATION ON SOLID PARTICLES IN SINGLE AND MULTIPHASE FLOW PIPES AND PIPELINES

The transport of glass particles in a 32mm ID plastic pipe has been studied using water, viscous water-glycol solutions and water with 500 ppm of corrosion inhibitor added. Particle sizes ranging from 30-200 pm in batches from 0.1-10g has been used. The particles have been activated in a nuclear reactor so that the particle velocities in very dilute suspensions can be measured using radiation detectors. A critical velocity is determined, above which the particles are suspended in the flowing fluid. This critical velocity increases with viscosity. To remove most of the particles, a velocity three times the critical one is needed, the presence of film forming amine type corrosion inhibitor makes removal of 30 pm particles very difficult.
