Abstract
The invention is used in the field of pressure-intensifying stations of natural gas and oil pipelines. The essential character of the process according to the invention is that steam is produced in boilers heated with the outgoing flue gas of the gas turbines driving the compressors (pumps), the steam is conducted into steam turbine for driving further compressor(s), pump(s). Main feature of the equipment according to the invention is that the ratio of the simultaneously operating gas turbines and steam turbines may vary from the equivalent to tripple value, the ratio is suitably double, and the stand-by machine unit is driven always by gas turbine, separate flue gas boiler is connected to each of the gas turbines, while the boilers are equipped with supplementary and/or substituting automatic heater. Advantages of the invention include the following: PA0 reduces the self-consumption by about 1/3rd, PA0 improves safety of the pressure-intensification, PA0 realizable in existing pressure-intensifying stations.
