Features and Benefits

Reciprocating CORKEN Gas Compressors

Corken offers five sizes of vertical, single-stage compressors (Models CORKEN 91, CORKEN 291, CORKEN 491, CORKEN 691, and CORKEN 891) for LPG/NH3 applications. The CORKEN compressors are available with threaded NPT or Class 300 RF flanged connections and cover a full range of capacities ranging from 7.0 to 198.8 m3/hr of liquid transfer. The Class 300 RF flange dramatically improves leakage containment and structural integrity.

Piston rod packing design…

Corken’s standard LPG vertical compressors are a plain style design using one set of V-ring packing. Most of Corken’s LPG vertical compressors use a single set of V-ring packing (plain-style). The only exception is the model CORKEN 891 which uses a combination of V-ring packing and segmented packing. Even though the model CORKEN 891 is a D-style compressor, it is the only D-style compressor that is not oil free. All other D-style compressors are oil free. V-ring packing consists of several V-rings, male and female packing rings, washers, and a spring while segmented packing consists of packing cups, spacers, O-rings, segmented packing, backup rings, and a spring. None of the plain style packing arrangements are oil-free designs. If oil-free gas compression is required, Corken’s D- or T-style compressors are recommended.

Single-stage design...

Corken’s single-stage compressors are typically used in applications where the gas compression ratio is less than 5:1. Generally, applications with relatively low differential pressures are well suited for a single-stage compressor. Transport, rail car, and marine unloading by vapor differential are examples of this type of application.

Custom engineered compressor packages available..

EDS offers standard mountings designed specifically for liquefied gas transfer, vapor recovery, and gas booster applications. If they do not meet the specifications of the application, EDS can supply a custom engineered package. Skid mounted units are supplied with control panels, safety controls, pulsation dampeners, receiver tanks, valves, and other special accessories as required.
