We computed the blading section parameters for a turboexpander built into a turboexpander generator plant to be used in fuel gas preparation systems for gas turbine plants of compressor stations. We profiled the blading, ran a numerical investigation in the ANSYS CFX software package, and analysed the results obtained. In addition, having studied available publications on the topic, we designed a flow diagram for fuel gas preparation featuring a diesel generator unit and a three-dimensional model of the plant comprising all the primary assemblies of the machine
