ABSTRACT:
A fluid pumping system for use with a natural gas dehydrating system or the like having an absorber apparatus for removing water from wet natural gas to produce dry natural gas by use of a desiccant agent such as glycol, and a glycol treater apparatus for producing a source of dry glycol from wet glycol received from the absorber apparatus including a main body having a control bore therethrough for receiving an elongate piston shaft; an elongate main piston shaft reciprocally slideably mounted in the central bore; first and second cylinders removeably mounted on opposite sides of the main body in annular centered relationship with respect to the piston shaft; first and second main pistons mounted at opposite ends of the piston shaft and sealingly slidingly received within the first and second cylinders, each piston dividing an associated cylinder cavity into a dry glycol pumping chamber and a wet glycol driving chamber; and each dry glycol pumping chamber being operatively associated with a pumping chamber inlet in fluid communication with the treater apparatus and a pumping chamber outlet in fluid communication with the absorber apparatus; each wet glycol driving chamber being operatively associated with a first and second reversible orifice system, each reversible orifice system having an inflow operating position wherein an associated driving chamber is placed in fluid communication with wet glycol in the absorber apparatus and having an outflow operating position wherein an associated driving chamber is placed in fluid communication with the treater apparatus. Removeable piston journal members of different sizes are provided for varying a volumetric imbalance between pumping and driving chambers.
