Analysis of numerical and physical tests of a rotary gas separator of conditional “2A” size

The authors chose a rotary-type gas separator with a body diameter of 69 mm (“2A” nominal size) to conduct research on plotting the dependences of power consumption, head and efficiency on supply, velocity and pressure diagrams. Studies of this type of equipment are not only of scientific interest. The results obtained can be applied by oil companies in practice.

Aim. The purpose of this research is to determine the complex characteristics of a rotary gas separator of conditional “2A” size in software packages, as well as during bench tests.

Materials and methods. The software packages «STARCCM+» and «Solid Works Flow Simulation» were chosen as software packages that allow to carry out the necessary calculations and virtual experiments. As a test of the adequacy of the obtained results, full-scale (bench) tests of the studied equipment design were also carried out.

Results. The obtained dependencies indicate the adequacy of the choice of software systems for constructing the pressure-flow characteristics of the gas separator under study, as well as the further possibility of studying the operation of gas separators of other designs (screw and vortex), various size groups and optimal liquid flows.

Conclusions. The use of software products makes it possible at the stage of designing equipment for the oil industry to build complex characteristics of gas separators, determine the dependence of the geometric parameters of the working bodies of the gas separator on a change in the complex characteristic, thereby identifying the most energy-efficient characteristic and optimal equipment design.
