| Many LPG (propane & butane) and agricultural ammonia piping systems do not have ideal conditions for net positive suction head (NPSH). As a result the poor NPSH conditions lead to excessive pump maintenance. Since reciprocating compressors are only exposed to vapors, poor NPSH conditions are not a factor. Many LPG and agricultural ammonia pressurized tanks such as tank cars and buried tanks have top unloading connections. A reciprocating compressor is the perfect solution for transferring liquids in this type of application.
Most Corken vertical LPG reciprocating compressors have single packed piston rods and none offer oil-free gas compression. The only exception is the model D891 which has two sets of packing (one V-ring and one segmented) but it is not oil free. Single packed, non oil-free compressors are typically used in non-corrosive and non-toxic applications where oil-free service and leakage containment are not critical. Typical applications include propane, butane, agricultural ammonia, and natural gas. |
