Mouvex API674 Engineered Triplex Plunger Pumps
For Gas Dehydration
The Process:
Gas dehydration is an essential phase in gas treatment before natural gas is sent to downstream process. Gas dehydration is accomplished using a liquid glycols absorption process (DEG, MEG, or mostly TEG) or solid desiccants absorption. In a TEG Gas Dehydration Unit, reciprocating pumps are used to pump lean glycol to the contactor where glycol absorbs water. After the rich TEG flows out from the contactor, it is regenerated and pumped back to the contactor. Because of the pressure difference between the regenerator and the contactor, a Triplex Plunger Pump is needed to generate the glycol flow.


Mouvex Triplex Pumps Advantages:
• Designed for very high volumetric efficiency (up to 95%),
Mouvex triplex pumps’ robust design built in compliance
with API-674 help gas treatment operators focusing on the
gas treatment process.
• With a proven reliability for more than 50 years and with
1000+ pumps operating worldwide Mouvex triplex pumps
require less maintenance and downtime period.
Meeting Customer Expectatio
• Pump skid built according your application
• Designed and certified for ATEX Zone 1 Ex II 2G IIC T4
• Customized according to required configuration (V-belt or
gear reducer)
• Single source accessories supply (dampener, safety valve)
• Long MTBF with extended packing lifetime and zeroemission
option
• Easy and quick maintenance.


Mouvex API674 Engineered Triplex Plunger Pumps
For High Pressure Injection Processes
The Process:
Methanol injection is used in oil and gas applications to prevent hydrates blockage due water content. Water injection (injection) is used to reinjected water (produced water or sea water) into the reservoir in order to keep a high pressure and thus extract oil and gas faster. For Enhanced Oil Recovery (EOR), Polymer injection is also used to maximize oil recovery by increasing water viscosity
Performance Data:
• Maximum Capacity: 108 m3/h (476 gpm)
• Maximum Pressure: 900 bar (13,053 psi)
• Maximum Temperature: 200°C (392°F)
• Maximum Pump Speed*: 490 rpm
* API-674 Maximum speed allowed but higher speed possible.
Meeting Customer Expectations:
• Available in 7 sizes with 12 different plunger sizes up to
420 hp (313 kW)
• From carbon steel to special alloys
• Designed for high-pressure high flow injections
• Compliant with API-674 (ISO 13710): Controlled crankshaft speed,
limited plunger acceleration requiring less maintenance and downtime periods.
• Manufactured according stringent standards: NORSOK, SHELL DEP’s, NACE, ASME…
• Different configurations possible for FPSO or Offshore installations
• Various lubrication options (internal or forced)
• Various tests possible: Vibrations, acoustic, non-destructive
