Liquefied Petroleum Gas (LPG) Solutions

Corken has served the liquefied petroleum gas (LPG) industry since the mid-1940s. LPG is a flammable mixture of hydrocarbons gases commonly known as propane and butane. These gases fuel vehicles, warm homes and businesses, and cook foods all around the world. Through the years, Corken developed a wide variety of compression and pumping solutions for autogas filling stations, bulk plant, tank car unloading, propane delivery truck, propane transport, and agricultural agricultural ammonia transport applications.

Each compressor and pump comes with a standard mounting. If the standard mounting does not meet the requirements for the application, Corken can modify it or design a custom engineered package from the floor up.

LPG Stationary
And Truck Pumps

Corken offers several models of sliding vane and regenerative turbine designs for a variety of LPG and agricultural ammonia applications. Each technology offers a wide range of differential pressures and capacities for bulk plant, propane delivery truck, and transport applications.

Sliding Vane Pumps
Corken’s positive displacement sliding vane pump is known as a Coro-Vane® and is an excellent choice for high capacity applications.

Regenerative Turbine Pumps
Corken's regenerative turbine pump is known as a Coro-Flo® and has a strong reputation in the LPG industry for being a long lasting pump. The free-floating impeller helps minimize wear and delivers years of trouble-free service.

LPG Reciprocating

To meet the stringent demands of today's LPG industry, Corken offers several models of vertical and horizontal reciprocating compressors . Depending on the level of containment required, each piston rod is sealed with single, double, or triple packing.

Vertical Reciprocating Gas Compressors
A single packed vertical compressor does not offer oil-free gas compression and is typically used in non-corrosive, non-toxic applications where oil-free service is not required and leakage containment is not critical. Single packed compressors are commonly used in propane, butane, agricultural ammonia, and natural gas applications

Technical Details

Horizontal Reciprocating Gas Compressors
When the pressures or capacities of the application are beyond the capabilities of a vertical compressor, Corken's horizontal compressors are the next option. Unlike the vertical compressors using V-ring packing, Corken's horizontal compressor uses a segmented packing design to seal the piston rod.

Propane Miser™

The new standard in railcar offloading captures 100% of contained propane in railcars (down to 0 PSIG) saving terminal operators up to $3.5M per unit over the lifetime of the system.

Technical Details

Custom Engineered

If a standard mounting does not meet the application requirements, Corken will modify an existing mounting or build a new one from the floor up.

LPG Dispensing Solutions

Corken’s regenerative turbine pumps are used for a variety of dispensing applications ranging from autogas filling stations, propane cylinder filling stations, and LPG carousel filling stations.

Cylinder filling stations fill portable propane cylinders—such as those used for back-yard grilling—one at a time.

Carousel filling stations fill large quantities of portable propane cylinders for mass distribution.

LPG Terminal &
Bulk Plant Solutions

Reciprocating compressors are commonly utilized for tank car unloading. After a tank car transports propane and butane to an LPG terminal, it's unloaded to a stationary bulk storage tank. A sliding vane pump is then used to fill propane delivery truck, propane transport, or agricultural ammonia transport.

LPG Truck &
Transport Solutions

Corken's truck pumps and bypass valves can be found on propane delivery trucks, propane transports, and agricultural ammonia transports around the world. Propane delivery trucks, also know as bobtails or lorries, are commonly used for home deliveries in rural areas while propane transport trailers make large deliveries to LPG plants with no access to a tank car unloading terminal.
