DESIGN , MANUFACTURE, AND TEST CAMPAIGN OF THE WORLD'S LARGEST LNG REFRIGERATION COMPRESSOR STRINGS

摘要

Increasing demand for LNG has driven the requirement for a significant increase in LNG plant capacity. Qatargas II, a joint venture initiated by Qatar Petroleum (70%) and ExxonMobil (30%), is committed to accomplish this while reducing plant emissions and making more efficient use of energy resources. The Qatargas II LNG project has applied APCI's AP-X? process for two large LNG trains (7.8 MTA) presently under construction in Qatar at Ras Laffan Industrial City (RLIC). Approximately 280 MW of refrigeration compression will be required to achieve this goal. This paper addresses the design, manufacture, and test campaign of the world's largest LNG refrigeration compressor strings.
