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.
