Turboexpander-compressor ADKG-40For large flow rates
Up to 40 MM m³/h
Up to -170°С
Up to 13,5 MPa
Magnetic suspension
Basic information
It is a natural development of ADKG-20, inheriting our proven solutions and the necessary modifications to work with high flow rates.
It is an essential element of technological designs and can be used to cool natural gas in low temperature separation cycles, fractional condensation separation, cyclo-ORC, dehydrogenation, liquefaction and other gas-bearing chemical processes.
It can be installed indoors at room temperatures 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.
