Determination of the expedient volume of using the technology of thermochemical recuperation for gas turbine plants of Ukrainian gas-pumping stations

We performed thermodynamic and technical-and-economic calculations of the scheme of thermochemical recuperation (based on natural gas reforming with combustion products) for 12 models of gas turbine plants of Ukrainian gas-pumping stations. It was established that, for most models, the pay-back period of investment to the TCR scheme does not exceed several months. We recommend to introduce TCR scheme at 40 gas turbine plants with a total power of 505 MW, and the cost of fuel that can be saved constitutes 420 mln. UAH per year.
