Texas Eastern Transmission LP (Texas Eastern) is seeking Federal Energy Regulatory Commission (FERC) approval to construct and install a new compressor station. The Cameron Extension Project includes the construction of a new greenfield compressor station, three new metering and regulating stations and related facilities, 0.2- miles (0.32- km) of 30-inch (76.2-cm) diameter interconnecting piping extending from Texas Eastern’s existing Line 41 at milepost 49.43 to a new interconnect with TransCameron’s East Lateral, and auxiliary facility installations and modifications at existing locations along Texas Eastern’s Line 41 in Louisiana.
The East Calcasieu Compressor Station (East Calcasieu CS), to be located in Calcasieu Parish, Louisiana, USA, will include one 25,500 hp (19,015 kW) Solar Titan 250 turbine-driven centrifugal gas compressor unit installed inside a Solar skid-mounted acoustical enclosure. Other auxiliary equipment includes an outdoor lube oil cooler, a turbine exhaust system designed with an adequate silencer system, a turbine air inlet filter system designed with in-duct silencer(s), an outdoor gas aftercooler, a unit blowdown/vent system, and a blowdown silencer.
The purpose of this project is to construct and modify natural gas pipeline facilities on Texas Eastern’s pipeline system in Louisiana to provide firm transportation service for up to 750,000 dekatherms per day of natural gas supply to its proposed LNG export terminal, authorized by FERC on February 21, 2019.
Emissions from the East Calcasieu CS will meet established technology and operational requirements to obtain and comply with the required air emissions permit. Measures proposed to minimize air quality impacts include the use of natural gas as the fuel for all combustion devices and use of SoLoNOX TM combustion technology to control NOX and CO emissions from the new compressor unit. The proposed new compressor unit will also be equipped with oxidation catalysts to further reduce CO, VOC, and HAP emissions.
