Presentation Transcript

  1. Glycol Pumps Circulation Rate: 3 to 450 gph Operating Pressure: 100 to 1500 psi

  2. A pump used for circulating glycol within a dehydration system. A pump used to circulate amine within a desulphurizer system. What is a Glycol Pump?

  3. No auxiliary power required Eliminates need for level control and dump valve at absorber Low gas consumption Completely sealed system prevents glycol loss Only two moving assemblies Hydraulic “cushioned” check valves with removable seats of hardened stainless steel Circulation Rates: SC Series 8 - 200 gph PV Series 3 - 450 gph Features

  4. Natural Gas Dehydrator Dry Gas Out Dry glycol Reboiler Absorber (Contactor) Wet glycol Wet Gas In Pump Dry glycol Heat exchanger surge tank Wet glycol

  5. Natural Gas Dehydrator Contactor Tower Glycol Cooler Reboiler Dry Gas Outlet Inlet Scrubber Wet Gas Inlet Surge Tank High Pressure Filter Excess Separated Gas Outlet Condensate Outlet Three Phase Gas, Glycol & Condensate Separator Condensate Outlet

  6. Piston ready to move to the right Wet Glycol from Absorber (High Pressure) Wet Glycol to Reboiler (Low Pressure) Dry Glycol from Reboiler (Low Pressure) Dry Glycol to Absorber (High Pressure)

  7. Piston on its way to the right Wet Glycol from Absorber (High Pressure) Wet Glycol to Reboiler (Low Pressure) Dry Glycol from Reboiler (Low Pressure) Dry Glycol to Absorber (High Pressure)

  8. Piston ring contacts actuator Wet Glycol from Absorber (High Pressure) Wet Glycol to Reboiler (Low Pressure) Dry Glycol from Reboiler (Low Pressure) Dry Glycol to Absorber (High Pressure)

  9. Actuator moves ‘D’ slide to the right Wet Glycol from Absorber (High Pressure) Wet Glycol to Reboiler (Low Pressure) Dry Glycol from Reboiler (Low Pressure) Dry Glycol to Absorber (High Pressure)

  10. ‘D’ slide shifts ports Wet Glycol from Absorber (High Pressure) Wet Glycol to Reboiler (Low Pressure) Dry Glycol from Reboiler (Low Pressure) Dry Glycol to Absorber (High Pressure)

  11. High pressure shifts pilot piston Wet Glycol from Absorber (High Pressure) Wet Glycol to Reboiler (Low Pressure) Dry Glycol from Reboiler (Low Pressure) Dry Glycol to Absorber (High Pressure)

  12. Reversal of flow shifts check valves Wet Glycol from Absorber (High Pressure) Wet Glycol to Reboiler (Low Pressure) Dry Glycol from Reboiler (Low Pressure) Dry Glycol to Absorber (High Pressure) Animation

  13. Loss of fluid circulation Runaway pump Hammering sound Pump skips Pump runs until normal temp. is reached Erratic pump speed Pump stalls Leaking check valves Valve body seal Dart seal Piston, piston rod seals Suction Lines too small Traps in wet glycol power piping send alternate slugs of glycol-then gas Plugged lines in dehy stystem Swollen O-rings Plugged passages in pump Blocked check valve Loose actuator Pump Trouble Shooting

  14. Gas blow-by to wet discharge Excessive service required ‘D’ slide seal or port plates Pilot piston seal failure Poor Maintenance Poor filtration Chemical contamination Pump Trouble Shooting

  15. Pump Trouble Shooting Swelling Shrinking Brittle Square O-rings (compression set) Extrusion – nibbled or partially dissolved One side flat Liquid condensate problems V Liquid condensate problems V Sour gas AF Organic acids V High temperature V High temperature V Swelling due to system fluids V Sour gas / Acid AF Abrasion Filters
