Accumulator Types and Application Names

1. Reflux Drum Accumulator
   – Used in distillation systems to collect condensed overhead vapor before refluxing or product withdrawal.

2. Suction Drum Accumulator
   – Installed before compressors or pumps to ensure steady suction pressure and prevent liquid carryover.

3. Flash Gas Accumulator
   – Separates flash gas from the liquid in refrigeration or LNG systems after pressure reduction.

4. Steam Accumulator
   – Stores steam for release during peak demand periods in power plants or process heating systems.

5. Surge Drum Accumulator
   – Provides surge volume to handle flow variations or system upsets in process systems.

6. Liquid Surge Accumulator
   – Manages sudden volume changes in pipelines and systems with highly variable flow.

7. Gas Surge Accumulator
   – Helps regulate pressure transients in gas handling systems.

8. Phase Separator Accumulator
   – Separates and stores gas and liquid phases after expansion or phase change.

9. Intermediate Pressure Accumulator
   – Stores gas or liquid at a pressure between high- and low-pressure levels in multistage systems.

10. High-Pressure Accumulator
    – Used in hydraulic or gas systems to store high-pressure energy for sudden release or backup.

11. Low-Pressure Accumulator
    – Provides low-pressure buffering in vapor recovery or gas handling units.

12. Ammonia Refrigeration Accumulator
    – Stores ammonia liquid and vapor for stable supply in refrigeration cycles.

13. Glycol Accumulator
    – Used in TEG dehydration systems to buffer glycol solution and prevent flooding.
