Dehydrating the gas through glycol stripping is an established and efficient way of producing a dry product. At the core of the process is a pressurized contactor tower where rising gas is brought into intimate contact with a downward flow of lean (dry) glycol. The glycol absorbs the water from the gas as they pass.
The Pump
Reciprocating pumps are used to generate the flow and high pressures required to circulate the wet glycol through a reprocessing circuit and return dry Glycol to the tower. Traditionally these have been gas driven or gas assisted pumps, unfortunately these are inefficient, carry a high burden of servicing and cause significant emissions.
Switch to RDP
Efficiency: Cross contamination of lean to rich Glycol eliminated. Less gas loss.
Emissions: 28-30% reduction of methane and other volatiles.
HAPs: Hazardous Air Pollutants reduced. VOCs reduced. Less regulatory requirement.
Servicing: Piston ring and seals less critical. Seal life extended. Pump Head and Stuffing Box servicing in situ. Valves in cartridge, easy removal and replacement.

Case Study
Ruhrpumpen delivers API 674 3rd ed reciprocating Plunger Pumps to Maloney Metalcraft for a Gas Dehydration Package in Algeria.
Maloney Metalcraft, under contract to Samsung, designed and manufactured the Gas Dehydration Package for the Timimoun Field Development Project which is expected to produce 1.6 billion cubic meters of natural gas per year over eight years.
Ruhrpumpen was selected for:
- Reliable and proven reciprocating plunger pumps
- Excellent knowledge of gas dehydration applications
- Strong technical support and responsiveness
- Packaging of the skid for a compact footprint
- Bespoke vertical gearbox to fit space constraints
- Competitive cost
During a tight 20 week delivery schedule Ruhrpumpen worked closely with Maloney Metalcraft on the design and manufacture of the pumps which were based on its RDP 70 Series Triplex product.
