Abstract:

A Combined gas and steam (COGAS) power plant with intermediate cooling in the process of compression operating on natural gas or gas hydrate fuel is proposed and justified for the design, manufacturing and use in Russia and other countries. A schematic diagram of the dissociator for COGAS power plant on gas hydrate fuel is proposed. The method of thermodynamic calculation and a computer program based on a single equation for all nodes and a power plant as a whole equation of the first law of thermodynamics for open systems with sources and sinks of working bodies with different total enthalpy are considered and brought to practical use, taking into account the supply and removal of mechanical and thermal power. The optimal compression ratios in compressors are determined from the conditionally maximum efficiency and output of the plant. It is shown that with rational parameters of the COGAS power plant with the proposed thermodynamic scheme, a gas or gas hydrate fuel plant with a thermal efficiency of 50% can be created with an initial gas temperature in front of a high-pressure turbine of 1500 K. When calculating the thermodynamic parameters of the production, transport, storage and decomposition of the gas hydrate fuel, the results of the thermodynamic properties of gas hydrates obtained at the Tyumen State University can be used. The developed version of COGAS power plant can be recommended for the experimental development and the creation of a facility using gas hydrates obtained from petroleum associated gases. The results of the performed studies show the prospects for the industrial introduction of COGAS power plant on gas hydrate fuel.
