Turbine Exhaust

In 1978, Shell Canada Limited commissioned a large aero-derivative gas turbine driven compressor unit in its Waterton Straddle Plant. This unspared unit provides the primary recompression service in the “Deep Cut” ethane extraction facility. Significant operating features of this unit include flat rating and three stages of waste heat recovery from the turbine exhaust. Throughout its history, this unit has demonstrated over 99% reliability and has operated for long periods without significant maintenance. All routine turbine maintenance has been accomplished on-site. This paper describes the features of the installation, the operating and maintenance philosophy, and the experience obtained from ten years’ service, thus providing the reader with insight in regard to features and practices which can provide for a successful installation.

Turbine Exhaust

This paper presents a unique application of two 14,200-hp gas turbines and their associated waste heat-recovery boilers in a refinery modernization program. It summarizes economics, design, and operating experience. Special emphasis is placed on three unusual features: (1) oversized starting turbines used as helpers; (2) control of two drivers with one governor; and (3) use of gas-turbine exhaust as combustion air, backed up by a forced-draft fan running at full speed against a closed damper.

With all the advancements made in the gas turbine technologies in the last 7 decades, a large amount (approximately 60%) of the thermal energy in the gas turbine exhaust is released in to the environment. This discharged heat could be profitably used not only in thermal utilities but also as an intermediate temperature heat source for the bottoming cycles producing electric power. This paper provides a systematic thermodynamic performance evaluation and comparison among the three different waste heat recovery solutions, namely, the Inverted Brayton Cycle, the Bottoming Brayton Cycle and the Organic Rankine Cycle. The results obtained from the parametric analyses of the CHP systems clearly identify advantages and limitations of the gas turbine technology and its size when combined with the three bottoming cycles evaluated in this study. A detailed discussion on the obtained results is presented in this paper.
