Turboexpander-compressor unit ADKG-5For low flow rates
Up to 5 MM m³/h
Up to -170°С
Up to 13.5 MPa
Magnetic suspension
Basic information
Designed specifically for low flow rates and based on the reliable and successful ADKG-10 series — an ideal opportunity to fully utilize the available resources.
It is an essential element of technological designs and can be used to cool natural gas in low temperature separation (LTS) cycles, fractional condensation separation (FCS), cyclo-ORC, dehydrogenation, liquefaction and other gas-bearing chemical processes.
It can be installed indoors at a room temperature of +5 .. + 45 C (UHL4 as per GOST 15150-69) and is designed as a monoblock with a horizontal shell connector. A single-stage centrifugal compressor and an axial turbine, usually single-stage with an inlet guide nozzle, are installed on the rotor of the replaceable flow part.
