Gas Turbine Generator and Cracking Furnace Integration

This paper includes a review of the benefits of integrating a Gas Turbine Generator with the Cracking Furnaces in an ethylene unit, review of critical design considerations for proper integration, and discussion of associated emissions issues.

Review of benefits will include:

· Effective GTG cycle efficiency

· Impact of integration on Cracking Furnace

o Fuel Firing

o Steam Production

o Thermal Efficiency

· Overall site benefits

Review of critical design considerations will include:

· Full range of GT operations

· Full range of Cracking Furnace operations

· Emergency/upset conditions

· Provisions for maintenance

Discussion of associated emissions issues will include:

· NOx emissions impact of non-integrated and integrated

· CO2 emissions impact of non-integrated and integrated
