An improved apparatus and method for transporting gas through long pipelines is provided. The invention provides a binary mixture (e.g. ammonia-water) KALINA CYCLE® that is used as a bottoming cycle with a gas turbine. The non-isothermal boiling and condensation of the binary mixture achieves a high degree of recuperation. By throttling a part of the binary mixture, cooling is provided to the inlet air chiller for the gas turbine air compressor, which significantly improves the performance of the gas turbine. Thus, the invention provides a system for inlet air chilling integrated into a gas turbine-KALINA CYCLE® combined cycle used in a gas pipeline compressor station for pumping natural gas. |
