Description

Slug Flow is a typical two-phase flow where a wave is picked up periodically by the rapidly moving gas to form a frothy slug, which passes along the pipe at a greater velocity than the average liquid velocity.

Process Engineers will Analyze the two-phase flow regimes and inform accurately whether the given fluid can cause slug flow while flowing through the piping system. On a broad scale normally following lines are believed to gave slug tendency.

*Vacuum Transfer Lines
*Condenser Outlet Lines
*Re-boiler Return Lines
*Fired Heater outlets
*Boiler Blow down lines.
*arious Pipeline Flowlines (Process Discipline to Confirm case by case)

Slug force is equal to the change in momentum with respect to time.

While performing slug flow analysis the following two assumptions are made

It is assumed that the slug is formed across the full cross-section of the pipe for the maximum impact. This configuration is least probable for vertically down word flow as no hold – up is possible for the accumulation of liquid and eventual formation of the slug. Hence slug force at elbows for vertically downward flow lines is not considered.
