Integration of Ion Transport Membrane Systems with Integrated Complexes,

Including LNG, GTL, CTL, Petrochemicals, Power Generation, and Utility Islands

Processes and devices utilizing solid-state mixed conductive membranes for producing oxygen or conducting reforming and partial oxidation reactions are emerging technologies.  Examples of these technologies include Ion Transport Membrane (ITM) technologies, ITM Syngas and ITM Oxygen.  The following references, and references contained therein, provide background on these developing technologies:

Large, integrated energy and petrochemical complexes continue to develop world-wide (e.g. Qatar, Australia, Russia).  Deployment of ITM technologies within these complexes or as “utility islands” nearby to these complexes can create valuable integration synergies.  ITM technologies may deploy toward grass-roots applications or toward the expansion of existing facilities (e.g. Shell Pearl GTL, Qatargas LNG).  Another attractive example ITM integration may be toward co-production of CTL products and power generation in China or the United States.

Liquefaction of natural gas to LNG is mature technology and widely deployed around the world today, for example a process using an LNG exchanger supplied by Air Products and Chemicals, Inc.  As ITM technologies continue to develop and deploy, it may be expected that ITM facilities may be constructed nearby LNG liquefaction facilities.  Valuable synergies are evident between these facilities:

  • Considerable value may be derived in an LNG liquefaction process when LNG flash gas may be valuably exported for use (e.g. instead of recycled).  ITM processes may provide value-added use for LNG flash gas.  LNG flash gas may be used as fuel to ITM pr...
