Abstract. The article, based on the methodology of systems optimal organization, proposes methods for improving the profitability of natural gas pipeline transportation implementing the multi-functionality principal. Based on CHEMCAD process calculations, the power systems designed use high-efficiency waste heat recovery from turbine-based gas transport units. This allows simultaneous generation of energy and increase of gas transportation capacity. It has been demonstrated that the multifunctional system that uses an organic Rankine cycle can generate over 9 MW of electrical power for a 16 MW gas transport unit as well as increase capacity by 1 % by additionally cooling the natural gas to be transported. An alternative solution proposed is a multifunctional system based on the Brayton cycle with supercritical carbon dioxide. Using this cycle allows generating roughly 4 MW of power and improve capacity by 2 % by cooling the natural gas before the centrifugal compressor.
