Analysis of separation devices shows that it is not always possible to achieve effective separation of liquid particles. Traditional methods for determining the sedimentation rate of particles in separators are based on the thermodynamic equilibrium of the main parameters (pressure, density) of the incoming gas flow. At the same time, well production, in particular condensing gases, is a non-equilibrium system, which is characterized by some delay (relaxation times) in changing parameters. As a result of this delay, the settling rate of particles in the separator does not have time to reach the steady-state Stokes regime, corresponding to effective separation.
The work proposes a non-equilibrium model for the settling rate of particles and establishes that for effective separation of liquid particles in a gravitational separator, the relaxation time for the settling rate of particles should not exceed 10 seconds.
