As a part of Bechtel, IPSI LLC has made significant contributions to the advancement of the ConocoPhillips Optimized Cascade ™ LNG Process.  Bechtel offers the world’s most accomplished team of in-depth LNG-related expertise. Several IPSI LLC process engineers are members of a permanent, integrated team of LNG technology and EPC experts who are devoted solely to the development of fit-for-purpose design and work process optimization of natural gas projects. This team works in coordination with ConocoPhillips to integrate Bechtel’s EPC expertise and IPSI LLC’s gas processing technology with ConocoPhillips’ flexible LNG process technology. A recent example is Atlantic LNG’s Trinidad project, where IPSI technology was used to designed a plant with a smaller footprint, contributing to substantially reduced costs and a shorter EPC schedule.

The Technology

IPSI’s enhancements to the ConocoPhillips Optimized Cascade ™ Process allow integration between NGL and LNG facilities.  This allows for increased flexibility and improves liquid recoveries by leveraging the very cold temperatures present in LNG facilities.
