Holloman Slug Catcher Debottleneck Completed in West Texas
This brownfield harp / finger slug catcher debottleneck project was recently completed by Holloman for a Midstream Operator’s gas plant in West Texas. Holloman was engaged to evaluate options for addressing the chronic liquid carry-over problems that occurred when the plant’s existing slug catcher received pigs.
Holloman identified the root cause of the existing slug catcher’s liquid carry-over malperformance by conducting a Computation Fluid Dynamics (CFD) Performance Study. Holloman then proposed an expedited turn-key solution to replace the slug catcher’s inlet separation section and associated inlet/outlet piping, while keeping the existing finger piping and foundations in-place.
A complete laser-scan of the slug catcher and its surrounding area was used to fast-track the engineering and design process, as well as ensure the ultra-tight tolerance that was required for tie-ing in the replacement sections. The project was delivered ahead of schedule despite the challenges presented by brownfield construction. After it was commissioned, the debottlenecked slug catcher was able to receive incoming pigs at full speed without liquid carryover.
