SYNOPSIS

With many oil and gas Plants driving sustainability efforts towards zero carbon emission, thermal waste such as open cycle gas turbine units have become one of the many areas for carbon footprint reduction. Open cycle gas turbine compressor stations typically lose about 68% to 71% of its exhaust thermal energy to environment.

The gas turbines could be equipped with a Heat Recovery Steam Generator to increase its efficiency. In the case where there are no steam users, another option is to go with Electrification, which is replacing the gas turbine with electrical drives. Among the benefits that can be realized are high compressor driver efficiency, improved heat rate of the Plant or grid co-generators, major reduction of carbon emission and utility gas savings.
The talk will be focusing on the feasibility study of such change from gas turbine driving a compressor to an electrical driver, encompassing the technology solution, design considerations, technical selection criteria and constraints, and economic modelling.
