Checkpoints for Process Plant and Equipment

Effluent Treatment Plant
Effluent Treatment Plant (ETP)
  1. Selection of proper material of construction for a new vessel/reactor, and modification.
  2. Proper design and fitting of vessel/reactor as per standard codes. Small bath size desirable.
  3. Operating conditions at less pressure, temperature, flow, slow reaction rate and less hazards desirable.
  4. Condition monitoring and pressure testing of vessels and equipment.
  5. Safety fittings like Pressure gauge, Temperature gauge, Rupture disc, Level indicator, Non return valve, Excess flow valve, interlocks, alarm and trips. Flameproof fitting where required.
  6. Safe operating procedure and safe close down procedure displayed for operator.

  11. Scrubber connections and scrubber working.
  12. Safe columns, condensers, receivers and vent and safety valve for distillation process.
  13. Auto and manual devices to stop heating, charging etc, and quenching or safe transfer of material in case of emergency.
  14. Close transfer/charging of hazardous material.
  15. Local exhaust ventilation on toxic material charging, transfer and filling/packing.
  16. Double earthing and static charge eliminator where required viz. Solvent in a glasslined vessel.
  17. Proper piping and colour code.
  18. Checking of proper O2/N2 lines and cylinders to avoid accident.
  19. Use of safety work permit.
  20. Machine guarding for drives, pumps etc.
