Prospects of optimize of energy on Gazprom Neft JSC objects with use of hydrocarbons

Authors: M.A. Misharin (Gazprom Neft JSC, RF, Saint-Petersburg), R.R. Absalyamov (Gazpromneft NTC LLC, RF, Saint-Petersburg)

Key words: power, energy, cogeneration, gas turbine, hydrocarbons, organic cycle.

The article presents the ways of optimization of the equipment and technologies at the gas energy objects of Gazprom Neft using a low-boiling working fluids (pentane, butane), and the results of computational studies. Using heat of exhaust gases of gas turbine plants is considered in the circuit with a low-boiling working media with the production of additional electricity, which allows increasing the efficiency of the plant by 10-20 %. The problem of increasing caloric fuel gas and as a consequence of the decrease in consumption in the gas turbine installation is discussed.
