Burckhardt Compression has been chosen to deliver numerous reciprocating compressors for Freeport LNG’s liquefaction and export project.
The customers, CB&I and Chiyoda (engineering) and Zachary (construction), selected Burckhardt Compression due to its highly flexible compression solution that provides best efficiency and best process controllability at varying gas conditions at Freeport LNG terminal.
During ship loading, natural gas, boiling off or being displaced by LNG (liquefied natural gas) flowing into the tank, is compressed up to 24/350 bara/psia. As a most economical solution, this gas is used to fire the pre-treatment facility’s gas turbine as a complementary supply to the gas from pipeline grid.
Burckhardt Compression’s Laby® Compressors have been used for decades for BOG (boil-off gas) handling in LNG receiving and export terminals and other cryogenic applications. The unique contactless labyrinth sealing system allows oil-free compression of LNG BOG at suction temperatures down to -170°C/-250°F. As no gas pre-heating or cool down is required at start-up, Laby® Compressors offer highest operational flexibility.
