Downstream
Overview
The final stage in the production process is downstream, where the oil and natural gas are processed and refined into usable products. ZOOK offers a complete solution for all downstream production processes.
In refineries and petrochemical plants, a variety of pressure relief devices are required including:
- Towers
- Knock out drums
- Heat exchangers
- Separators
- Accumulators
- Flare stacks
- Sulphur recovery units
- Pressure relief valves
- Storage tanks/batteries
Pressure Relief Valve Isolation
The primary reasons for applying rupture disks downstream of pressure relief valves are:
- Prevent corrosion of relief valve
- Reduce cost of relief valve by negating costly special alloy trim/internals
- Prevent fouling or sticking of the relief valve
- Prevent variable superimposed backpressure from affecting relief valve
- Detect opening or leakage of relief valve
- Elimination SRV emissions -valve isolation
Storage
Storage is another component of downstream operations. Rupture disks are utilized on the storage tanks.
