APPLICATIONS: Circulating pump for gas glycol dehydrators Circulating pump for gas amine desulphurizers
FEATURES: Eliminates absorber liquid level controls No auxiliary power supply required Low gas consumption Completely sealed system prevents loss glycol No springs or toggles, only two moving assemblies Hydraulic “cushioned” check valves with removable seats of hardened stainless steel
OPERATION: Materials for the vital working parts have been selected for greatest wear resistance. These materials include stainless steel, hard chrome plating, satellite, nylon and teflon. Moving “O” Ring seals are compounded specifically for ethylene glycol service. A complete operational check is given each pump after assembly. “O” Ring sealed check valve darts are standard in all except the model 315 PV. Teflon sealed darts are available. Capsule type ball checks are used in the 315 PV and are available for 1720 PV, 2015 SC and 4020 PV.*These pumps are designed for operating pressures between 100 and 500 psig maximum design pressure for all models is 1500 psig.
**Maximum output is affected by system pressure drops. See system operation parameter for maximum output curves.
:
MAXIMUM DESIGN PRESSURE FOR P.V. MODELS IS 2000 psig AND S.C. MODELS IS 1500 psig

Dehydration Pressures
Stall Graph
Advantages: • Long life / high cycles • Elimintates the use of a Liquid Level
Controller • Does not requiere external source
of power. • Low Linear velocity in Piston O-
Rings • Completely sealed system prevents
glycol loss. • Does not leak when failing • Only two moving parts
Disadvantages: • Gas Emissions to atmosphere • High Operating Cost due to emissions • Pulsation • Elastomers have to be compatible with
process fluid • Check Valves wear • Can mix dry glycol with wet glycol if piston
seal fails
• Approximately 36,000 glycol dehydrators in the natural gas production sector are used to remove water from the gas.
• Most glycol dehydration systems use triethylene glycol (TEG)
• Gas-assisted pumps are the most common circulation pumps in remote areas that do not have an electrical power supply
• Typical methane emissions are about 1,000 cubic feet (Mcf) for each million cubic feet(MMcf) of gas treated.
• Replacing gas-assisted pumps with electric pumps increases system efficiency and significantly reduces emissions. For example, a 10 MMcf per day dehydrator could save up to 3,000 Mcf of gas a year, worth $21,000.

Take Away • How an Energy Exchange pump works • Sizing an Energy Exchange Pump • Different Dehy configurations for Energy Exchange Pump and
Electric Pump. • Energy Exchange Glycol Pumps have gas consumption and
environmental concerns. • Electric Glycol Pump can pump Corrosive and Erosive Fluids. • Electric Instrumentation is essential to avoid emissions to the
atmosphere. • It is desirable to work with the Electric Pump and use the
Energy Exchange pump as a Backup • New Kimray Dehydration Technology using Electric
