Slug Catcher Overview

A Slug Catcher is a static pressure vessel or piping system installed at the front end of a gas processing facility or pipeline to collect and temporarily store large volumes of liquid slugs (liquid surges) carried along in a gas pipeline. It protects downstream processing equipment from hydraulic shock or overflow.

🟦 2. Key Engineering & Equipment Topics

🔹 a. Piping

  • Inlet manifold from pipeline or wellhead

  • Gas outlet to separators or processing units

  • Liquid outlet to storage tanks or knockout drums

  • Bypass and drain lines

  • High-pressure piping with pig receiver interface

  • Erosion-resistant internal linings (for sand handling)

🔹 b. Civil Foundation

  • Structural supports for large diameter vessels or piping

  • Pile or raft foundation for finger-type slug catchers

  • Load distribution pads for modular skids

  • Earth grounding for lightning and static protection

  • Spill containment bunding for liquids

🔹 c. Pumps

  • Condensate transfer pumps

  • Produced water disposal pumps

  • Drain sump pumps

  • Sand slurry pumps (if applicable)

🔹 d. P&ID Elements

  • Inlet and outlet headers

  • Instrumentation ports (level, pressure, temp)

  • Sand removal line

  • Emergency shutdown valves (ESDVs)

  • Pig receiver interface (if upstream pipeline pigging involved)

  • Drain and vent lines

🔹 e. Related Heat Exchangers

  • Gas coolers or heaters (before or after slug catcher)

  • Condensate heaters (to avoid wax crystallization)

  • Intercoolers for gas recompression systems

🔹 f. Instrumentation

  • Level transmitters and alarms

  • Pressure transmitters on gas/liquid sections

  • Temperature probes

  • Flow meters (especially for liquid outlet)

  • Sand accumulation sensors (if applicable)

  • Remote monitoring system (SCADA/PLC)

🔹 g. Day & Temporary Storage Tanks

  • Condensate storage tanks

  • Produced water surge tanks

  • Sand slurry collection tanks

  • Emergency overflow tanks

  • Temporary storage for cleaning or maintenance

🟦 3. Process Design Elements

  • Liquid retention time based on expected slug size

  • Inlet momentum and gas velocity control

  • Phase separation efficiency

  • Settling velocity of sand and solids

  • High turndown ratio (must handle both trickle flow and large slugs)

  • Safety factors for pipeline pigging operations

🟦 4. Mechanical Design Considerations

  • Pressure design per ASME Sec VIII, Div. 1/2

  • Materials to suit sour service (Hâ‚‚S, COâ‚‚ – NACE MR0175)

  • Corrosion allowance (internal erosion protection)

  • Vessel or piping type (horizontal vessel or finger-type)

  • Large nozzle and header designs

  • Seismic and wind load analysis

  • Hydrotest and radiographic testing
