RESULTS OF ENVIRONMENTAL RETROFIT FOR GAS PIPELINE GAS-PUMPING UNITS

摘要

Provision of an environmental friendliness is an important global challenge. This is why the improvement of the environmental characteristics have involved the development of the gas turbine engines (GTE) applied to the gas pipelines as a natural gas blower drive. Stationary GTEs have been run on gas pipelines for some decades. During this time, the environmental norms have become much more demanding. In connection with this, an environmental update of the operated gas-pumping units becomes necessary. Tasks of the environmental update as applied to the existing gas-pumping units are, in principle, different from those confronting the engineers involved in development of improved machines. The paper presents some engineering approaches developed at the NPP "EST" (Russia) and put into effect as a result of joint efforts undertaken by the "EKOL" (Czech Republic), including solutions of the research-engineering concepts, combustor designs and test findings for the updated gas-pumping units of the following types:: GTK-10 (Nevsky Works, 10 MW), GT-750-6 (Nevsky Works, 6 MW), MS-3002 (General Electric, 10 MW), KWU VR-438 (Siemens, 10 MW). The experience of the environmental retrofit for over 500 GPUs on the compressor stations of Russia, Ukraine, Kazakhstan, Czech Republic, Slovak Republic, Germany, and Hungary is described.
