Evaluation and Improvement of the Performance of a Wellhead Multistage Bundle Gas–Liquid Separator

A wellhead multistage bundle gas–liquid separator combining a cylindrical cyclone (GLCC) with multi-tube components is expected to improve the separation performance. However, there no unified understanding of factors influencing performance separator. The continuous improvement and applications are restricted. This paper evaluated using numerical simulation method. results indicate that flow field evolves be uniform increased water cut when gas–oil ratio rate remain constant. Compared 30% cut, efficiency at 50% by 5.88%. When remained constant, swirl effect primary was enhanced. more than 70% 15 m/s. unchanged, pressure reduced. greater 160 m3/t, trace density secondary reduced, also lower 60%. can further improved optimizing number diameter bundles.
